Hi Gerardo,

I agree with you that there is a need for discussion about the pros and 
cons of both drafts. I have not read draft-wakikawa-nemo-v4tunnel so I 
can't make any comments on this draft. However, we have made an 
implementation of  draft-soliman-v4v6-mipv4 and our experience is the 
same as yours, it works very good and requires small changes to the 
MIPv6 stack.

Regards
Conny Larsson

  <pre wrap="">Hi Raj,

I have two general comments about making draft-wakikawa-nemo-v4tunnel a
WG item:

- I agree with you that the scenario you described is the most
interesting one and I'm favor of focusing on it immediately. However I
think that before having consensus on this solution draft, we should
understand if there is consensus on scenarios we want to address and in
particular if there is consensus to address only this particular
scenario. At least I thought this was the MIP6 WG original intention
since MIP6 charter states that the WG will document a problem statement
related to IPv4/IPv6 transition issues.

- I wonder why draft-soliman-v4v6-mipv4-01 has not been considered as a
candidate WG item (at least for MIP6). I'd like to see a discussion
about the pros and cons of both drafts. In my view they tackle the same
scenario in a very similar way. The main difference is the BU message
format: based on draft-wakikawa the source address of the IPv6 packet is
the HoA, since the message is treated as a particular de-registration;
in draft-soliman the source address is the CoAv4 mapped in IPv6 address
format. I'd like to understand better the rationale behind the choice in
draft-wakikawa. Personally, I think that the approach of draft-soliman
is a little bit cleaner since the BU is not considered a de-registration
message. BTW, we implemented draft-soliman: it requires few changes in
MIPv6 stack and works great.

Subject: [Mip6] Consensus call on making ID 
draft-wakikawa-nemo-v4tunnel aMIP6/NEMO WGs document



One of the major barriers to the deployment of Mobile IPv6 today is
the fact that most access networks are IPv4 only. A number of hosts
are already dual-stack capable. While Mobile IPv6 works well in IPv6
networks, it is essential that IPv6 mobility service continue to work
even when the mobile host is attached to an IPv4 network. The same
applies to a NEMO mobile router as well. 

A number of transition scenarios have been identified in IDs: 
1. draft-larsson-v6ops-mip-scenarios-01
2. draft-tsirtsis-dsmip-problem-03
While discussion of these scenarios in the larger scope makes sense,
there is a need to focus on the most critical scenario that would
address the MIP6 host and router problem. The problem in a single
sentence can be stated as: "Mobile IPv6 hosts and routers (NEMO) need
to be able to reach its (IPv6) home agent and services when roaming in
and attached to an IPv4 access network."
It makes sense to focus on just this one scenario and solve the
problem immediately. 

The ID: draft-wakikawa-nemo-v4tunnel-01 solves the problem of a MIPv6 
mobile node or a NEMO mobile router roaming onto a IPv4 only access
network in a simple manner. 
It is intended that the standardization of this solution in the IETFs
MIP6 and/or NEMO working groups proceed. The working group chairs have
reviewed and discussed this work item. It has also been presented at
the MIP6 and NEMO WGs at IETF62. 

The chairs would like to hear your thoughts in order to see if there
is consensus to make it a WG document and progress it as a standards
track RFC. Comments should be sent to both the NEMO and MIP6 WGs. 

If we have consensus, then the document will be pursued as a dual WG
item and called draft-ietf-mip6-nemo-v4tunnel-xx.txt 

Make I-D draft-wakikawa-nemo-v4tunnel a MIP6/NEMO WG ID:
	For 		[  ]
	Against 	[  ]

How are you going to fix this Vijay?  I use 15s keepalive with ICMP.
Would you do similarly?

We also have an implementation but it is not documented, however, 
experiments were reported on Section 3 of expired draft 
draft-lach-nemo-experiments-overdrive-01.txt http://tinyurl.com/3om6x

It uses IPv6 in UDPv4 for NAT traversal.  The HA and the Gateway are not 
co-located.

That does not use IPv4 CoA for MIP6 simply because when behind NAT it's 
little relevant.

It uses UDP port scanning to find out open ports and 15s icmp "heart 
beats" to maintain port state unchnaged in the NAT devices.

When sending big packets over asymmetric wireless links (like GPRS and 
UMTS) the v4 stack fragments but the v6 stack does not fragment.

here your concern is that we are not looking at enough scenarios.

so, you have two issues. 1) how to make the HA's IPv4 address
accessible through the IPv4 Internet and 2) we need to step back
and look at more scenarios.

I agree we need to address 1). and there are some solutions.
you havent responded to them in my mail. but for 2) I am afraid
you havent given any justification. draft-larsson has an
exhaustive catalog of all kinds of scenarios. please point to
the scenario which you think is important and we can take it
from there.

Vijay

Amen!!!

I would be very interested if your requirement were in place: "One
requirement that I believe is highly desirable is the ease of deployment
of a solution that enables Mobile IPv6 traversal in IPv4 networks."

This would allow us to consider v6 for the mobile platform without
worrying about installing a full global v6 infrastructure to support
them.

Sri/Vijay

And I'd sure like it if the discussion considered options to "home
agents".  I fail to comprehend how I move state for routing, QoS,
security, and capacity for hundreds of users/applications on mobile
platforms around on a global scale through home agents, especially if
I'm joining someone else's network (i.e. one airport to the next).

Try imagining teleporting an engineering building from your corporate
campus instantly onto the campus of your biggest competitor and have all
network connections maintained, your VPN's not dropped, routing continue
un-interrupted, security maintained, QoS maintained, and you have
equivalent network capacity.  This is what we are beginning to try to do
with large mobile platforms today.  Now I don't honestly believe we can
achieve all of this; but it seems like this should be our goal.

Take care

Hi Sri,

  Looking at things from an operational or deployment perspective:

  One requirement that I believe is highly desirable is the ease of
deployment of a solution that enables Mobile IPv6 traversal in IPv4
networks.  Additional network infrastructure and/or a complicated
protocol will take us further from the base MIPv6 protocol - which
impacts the ease of deployment and possible acceptance.=20

   It would be highly desirable for operators and users not to have a
requirement that their Mobile IPv6 service be dependent on a separate
transition service. =20

  Finally, co-existence of Mobile IPv6 (a feature of IPv6:) with IPv4
networks is a mandate that we must adhere to ASAP; otherwise, there will
be little acceptance to advance Mobile IPv6 adoption/deployment  [just
think if we waited for the core IPv6 specifications to become RFCs
before working on v6ops stuff - where would will be with IPv6 deployment
today].  draft-wakikawa-nemo-v4tunnel-01 limits the scope to what I
believe is the minimum scenario and requires little protocol changes.
Let's keep in mind the operator's perspective in the debate.=20

   Carl

The question is not about configuring a v4 address on the
interface of v6 home agent, it about the termination point
of the v4 network and the placement of a v6 home agent. You
cannot expect the v6 home agent and the transition gateway
service to be co-located. The point is that we should identify
the practical deployment sceanarios and go from there.

Other way to say is we would not an extra encap layer, when
the home agent and the transition gateway functions are spread
out.

Hi Raj:

I too would support Sri's excellent analysis.

I am very surprised to see this consensus mail, given that during the last IETF meeting, several people had raised the concerns similar to what Sri has described  in his mail regarding that draft. Not  clear what has changed since then.

Hi all,

I agree that we need a mechanism for mobile hosts/routers to keep IPv6
mobility functions even if they jump into IPv4 network.

Personally, I am not sure if we need to save 40bytes instead of using
some other general tunneling mechanism.  But, I also personally feel
that we need much time if we wait for a general tunneling mechanism to
be defined, which we don't want to.  Defining a simple traversal
mechanism in MIP6/NEMO protocol makes sense to me.

The proposal (draft-wakikawa-nemo-v4tunnel) is simple enough and it
looks easy to implement from implementor's point of view.  It only
focuses IPv6 mobility which seems a good tradeoff to me.

However, I still don't fully understand the pros and cons between
draft-wakikawa-nemo-v4tunnel and draft-soliman-v4v6-mipv6.  I want to
see which is better for our purpose.

Not necessarily.  There's always room for optimization but the 
tradeoff is worth considering.  The question is what level is "good 
enough".

I've no doubt that it's doable,a nd these assumptions seem OK to me.

But instead of using mechanisms which require no protocol 
modifications or new code at all, you're plugging v4 tunneling 
functionality to MIPv6.  In other words, inventing something new.

That's a bit uncomfortable because MIPv6 was not designed for v4:
There are a couple of things why I think this is a problem:
  - People could even leverage the length of v6 addresses e.g., for 
CGA-based authorization instead of return routability (or something 
like that).  But extending MIPv6 in a manner that would eliminate that 
room for expansion.
  - We may not (yet) be fully aware which parts of the spec this has 
(non-obvious) implications to
  - we end up having to re-invent a lot of stuff, like NAT traversal, 
keepalives, possibly needing to also do NAT traversal to reach the 
Home Agent, etc.  And we have a number of encapsulation mechanisms. 
All of this seems like something that we do NOT want to re-invent in 
MIPv6 unless it can be justified that using existing mechanisms and 
existing configuration methods is not good enough (the crutch appears 
to be saving 20 or 40 bytes of payload).

Would the next step be to bind an IPv4 CoA to IPv6 CN ?

Those seem OK, though I'm not sure what the security folks would say.

Yep.. but it's non-standard, right?  How can products from different 
vendors and operators interoperate?

Hi Vidya

I see words about complexity from you and Keiichi. I agree we need to
look at how complex the proposals are:
- in terms of standardization
- in terms of coding
- and mostly in terms of deployment

Obviously, a solution that has less constraints is easier to deploy.
Ending the IPv4 at the HA is a constraint. We have experiments with
customers who could not do that for very pragmatic reasons. Details
might be given mater.

In terms of coding, I guess that people have to read and understand all
proposals on the table before they can assess that one thing is more
complex than another. I would assert that a solution that does not
change the home agent causes less regression testing then one that does.
For instance, Doors is a very small footprint hack that leaves the end
to end MIP untouched.

In terms of standardization, I'd guess that the same applies. Changing
MIP inside is not as simple as changing it on the surface. Doors just
acts on the transport. The Doors gateway can be installed on the HA,
close to the HA, or by an external provider anywhere.

I'd just suggest that we, as a group, do not presuppose that because
Doors provides additional features it is necessarily more complex.
Sometimes, simplicity brings a lot of good things with it.

Pascal

Doors uses the BU as keep alive.=20

Just tune the Binding lifetime according to your needs. In general, 30s
was fine with us.

Actually I was at the MIP4 WG meeting and I remember the agreement you
mention :)

Note that, as said in my previous email, I am in favor that MIP6 deals
with scenario 1. My point is that, as stated by Henrik, James and
others, we need an agreement in MIP6/NEMO WG (and not in MIP4 WG) on the
scenario(s) to be considered and in particular if the WG agrees to focus
only on the scenario tackled by draft-wakikawa.=20

>=20

Actually I'm not sure that draft-soliman-v4v6 deals also with scenario
2. Note that I'm not advocating draft-soliman. I'm just saying that
draft-soliman is a possible alternative solution for scenario addressed
by draft-wakikawa and we need to consider pros and cons for both of
them. Actually, in my view the two drafts are very similar and working
on their differences should be very easy.=20

>=20

well, sending a new BU you replace the existing binding cache entry. I
don't see the need to do a de-registration for IPv6 CoA and a new
registration for IPv4 CoA. Simply sending the IPv4 CoA (mapped in IPv6
format) will cause the BCE to be updated. Am I missing something?

Agreed...

Another angle is that HAs are already being sold and deployed. There is
value in incremental features that do not change the HA and the
surrounding infrastructure.

For instance, in the PE-Based model, corporations only own the routing
within their VPN, and the global addresses are owned by the service
provider. Unless they deploy a specific exit with DMZ, firewall and so
on, they will not have a single box with a global IPv4 address to put an
HA on.=20

Do we want to limit the solution to these corps that have a DMZ?

the HA

for
| the HA's IPv4 address and tunnels them to the HA deep in the IPv6
network.

DMZ
| and the HA deep in the IPv6 network. another option is to place the HA
in
| the DMZ. but he doesnt want to do that. I will be discussing with him
to

dont

Don't forget IPR encumburances (if any).

A mechanisms without IPR claims is much more likely to actually get 
implemented by certain communities.

A couple of clarifications regarding the consensus call:

1. The intention is to address the following scenario:
"MIPv6 and NEMO capable Mobile hosts/routers attaching to an IPv4
access network need the capability to create a tunnel and be connected
to their MIP6 home agents."
This is the scenario that is most applicable for MIP6 deployment.
There are plenty of other scenarios as well. But they are much more
of academic interest at this time and hence not really in the scope
of this discussion. So I would suggst that we do not go off on a tangent
discussing all these other scenarios.

Do you agree/disagree that the above scenario is the one that needs
to be solved ASAP?
(Note: It does not imply that other scenarios are irrelevant. It simply
means that this is the scenario worth working on and has the most=20
significant priority or value for MIP6 deployment.)

2. ID:  draft-wakikawa-nemo-v4tunnel can be used as the baseline. It
does not imply that we are ruling out draft-soliman-v4v6-mipv6 or any
other. The IDs can be combined w.r.t the parts that address this =
scenario.
Additionally once it is a WG document, what goes into the ID is decided
by the WG. So lets not get into arguments of what or whose draft is the
one that should be made the WG document.

| there is some mis-understanding regarding the relation

| scenario of a v6 MN or MR accessing its v6 home agent from
| a v4 only access network. draft-soliman talks about using a
| IPv4 mapped IPv6 address to convey the IPv4 CoA to the
| HA. draft-wakikawa uses a new mobility option to carry
| the IPv4 CoA. I personally prefer carrying it in a separate

|=20
| regarding Sri's concerns, we do intend to address them. dont

|=20
| - the HA's IPv4 address is reachable through the IPv4 internet
|=20
| Sri is questioning this assumption. he is claiming this is
| not so easy. he doesnt want IPv4 routing inside his IPv6
| network. the HA is deep inside in the IPv6 network. for the
| HA's IPv4 address to be reachable, you might need a box in
| the DMZ, which traps the packets for the HA's IPv4 address
| and tunnels them to the HA deep in the IPv6 network. but here
| we end with extra tunneling between the box sitting in the
| DMZ and the HA deep in the IPv6 network. another option is to
| place the HA in the DMZ. but he doesnt want to do that. I
| will be discussing with him to see how we can come up with a
| solution. Sri, let me know if I still dont understand the
| issue you are bringing up.

Even better would be that this "box in the DMZ" terminates V4, and sends
packets to the HA in IPv6. Say, doing some NAT-PT instead of tunneling,
classical alternates.=20

OH, yes but then if you do it right, you could try to avoid exposing
IPv4 to the HA at all, since now we are IPv6. Interesting...

Seems to me that the line if thought that starts at your "box in the
DMZ" ends up being With Doors.

With Doors, the "box in the DMZ" is the Doors gateway between IPv4 and
IPv6.=20

The Doors GW is fully stateless and inherits from 6to4.=20

The closest Doors Gateway could be advertised by means of DHCP / IP NCP
so most of the way is done via IPv6. Or the MN/MR can be statically
configured with a GW from the ISP. Or, providing that the ISP configures
a revNAT state in its PE or managed-CE box, the Doors GW can even be
deep within the IPv4 private network (works fine ;). Or, if you have
one, you can place the GW in the DMZ. Might be easier to turn Doors GW
on (one line) then to migrate the HA there. =20

Then again, implementing Doors is in fact a very small piece of code in
the MN/MR and the GW. It is mostly a design point. Consider it.

Hi Pekka:

There's IPR on Doors, not hiding it. For instance, Cisco has published
terms that were supposed to allows opensource implementation (same terms
as IPR for basic NEMO aspects).

If there's still a problem regarding IPR, someone please let us know.
We'll work on it as we did in the past.

Somehow yes.  Our implementation works with both MIP6 and MIP4.  Our 
implementation does not use v4 CoA in BC, and does not use double v6 
encapsulation if the Gw is co-located with the HA.

Hi Raj:

I suggest that we agree on whether we want NAT/PAT/RevNAT traversal or
not.=20

We had this debate some time ago at NEMO, and I presented this at IETF
56::
http://mobilenetworks.org/nemo/ietf56/slides/ietf56-nemo-ipv4traversal.p
pt=20

That day, we voted that IPv4 traversal was a GOAL for the WG.

In particular, the discussion turned around NAT which appears to be
really centric to this problem.=20

My personal sense is that we DO NEED (all sorts of) NAT traversal. And
it's not impossible if we accept that it works in an agreed upon 'MOST
CASES'.=20

Pascal

One Issue #1, You slightly restated #1. The HA need not be
configured with IPv4 address. You have made extensive arguments
in the previous IETF's regarding doors using a double tunnel
by having a NEMO tunnel in a transition tunnel and that this
current draft does not do that. You have not made it clear as
how you were able to avoid that extra tunnel. The draft does
not talk about the scenario where the transition gateway and
the home agent functions are decoupled. However, we are now
saying that this draft can do all that by what ever schemes.
No thoughts went in to see how the Doors solves the same issues
and if Doors required the home agent address to be configured.

Issue#2, Yes. We need to step back. We cannot just say the
current draft is the basis for the solution. Before we narrow
down on one solution draft, there have to be some discussions
on the problem scope. I'll not just identify the scenario from
your list, there has to be some debate and consensus on the
problem scope and that will come out when we look at all the
current solution drafts that are out there. So, the problem
scope will come out when we review all the current solution
drafts. This is my view, you are free to disagree.

Sri

Raj:

In general I agree that the v4 traversal problem should be solved.
My concern is adopting the draft you mention below as the working
Group item and adopting it as the basis of the solution. 

During last ietf, a number of issues were raised. We need to 
address those issues - is all forms of NAT supported; why should the
Solution mandate v4 and v6 collapsed at the HA; what are the pros/cons
Of proposed solution vs other proposals - doors draft, draft 
from Hesham/George et.al?

Vote YES for a solution for v4 traversal.
Vote NO for adopting this draft as "the base solution".

Please, don't even consider translation.

You may be interested of the following:

"Reasons to Move NAT-PT to Experimental"
draft-ietf-v6ops-natpt-to-exprmntl-00

AFAIK, that has just recently been forwarded to the IESG for 
processing.

Doors does not solve the problem if the strict requirement is avoiding 
"extra" encapsulation, right?  (I may not buy that requirement myself, 
but we should at least get to consensus whether it's one or not.)

Doors is basically Yet Another v6-in-v4 Tunnelbroker (albeit 
stateless) Solution, AFAICS.  If we go down that path, maybe it would 
be worth using the already specified, implemented and deployed 
mechanisms, or create one ourselves (there was a Tunnel Configuration 
BOF at the last IETF.)

Raj:

If you are seeking a re-vote on this:

1. Agree - vote YES 
2. NO to starting with a presumed base. Looking at the discussion and
position being taken, I would prefer to start with a clean slate as a
base. Definitely, this implies that all inputs should be weighed in
judiciously.

Raj,
    We do want to solve the IPv4 traversal, however NAT/PAT
traversal support is the critical requirement for that.
Based on our Mobile IPv4 deployment experience, we have seen
lot of interest for NAT Traversal and MIPv4 WG standardised
on RFC 3519. The same requirement is central to the problem
statement here.

   On your question, if we can adopt draft-wakikawa-nemo-v4tunnel
as the basis for the solution, my answer to that is "NO". There
are other solution documents out there and we need to review
them as well.

Regards.
Sri

Hi Pekka,

I agree with you that saving the extra encap should not be
the central focus. If saving few bytes is of paramount
interest, there are header compression techniques that we
can apply to doors. Choosing a solution by basing this as
the central argument is not right.

I guess it can be difficult. I was worried about this too, but didnt
want repeat all the requirements. will ask the working group about this.

okay.

the text on dynamic keying part has changed. for IKEv1 we talk about
Phase 1. for IKEv2, we talk about IKE_AUTH exchange. but we cant just
state that. need to explain why the HA needs to check if the identity
presented in IKE_AUTH exchange is allowed to create security
associations for a particular home address.

suggestions to improve this are welcome.

not different. I see the problem very well now. some requirements I
am repeating from 3776. will fix this, based on what the working
group decides.

yes.

no. if the MN initiates IKE exchange, the HA can just populate the
SPD from the IKE exchange. it doesnt need to create a SPD entry for
a specific HoA.

I prefer the bootstrapping document just pointing to this section
for HoA configuration.

hello all,

I have created an online list of issues for draft-ietf-mip6-ikev2-ipsec. 
http://people.nokia.net/vijayd/mipsec/issues.html.
one can open new issues by sending a mail to the WG mailing list.

I would like to hear WG opinion on Issue 1. currently, the draft makes a 
lot of references to RFC 3776, especially with respect to requirements 
on the MN and the HA. I seemed to have repeated a few too. my intention 
was to only list exceptions and new requirements in this draft.

there are pros and cons. a lot of work went into RFC 3776 to come up 
with a set of requirements that make sense. if we attempt to list them 
in this draft, we might end in a state where the requirements in the 
draft conflict with the requirements in RFC 3776. since we already have 
an RFC we can refer to, no reason to repeat the text.

OTOH, it makes this draft self contained without having to refer to RFC 
3776 for the requirements.

Vijay

Folks,=20

Sorry for the late reply, I've been trying to catch up with
the concensus thread as I've been travelling.=20

I think there are a number of issues there and the discussion
seems to confuse those issues. draf-wakikawa is only addressing
one scenario and should not be seen as _the_ transition solution.
I think that would be a mistake.=20

But let's take a step back, draft-larsson has outlined basically
all scenarios that might exist. Before we make a WG draft, shouldn't
we discuss what scenarios we want to address? and why? If we decide=20
on the scenarios, then draft-wakikawa might be included as one tool,
that is part of the overall solution.=20

Personally, I see no reason for having another MIP-based traveral=20
solution, and I'll explain why.

There are already multiple NAT traversal solutions that are not=20
specific to MIP. And there are others based on MIPv4. when it comes
to enabling IPv6 in a private IPv4 cloud, I think it makes sense to
used MIPv4 with its built-in traversal techniques. In this case,=20
I think draft-tsirtsis makes sense, or another draft along the same=20
lines.=20

If you want to use MIPv6 only, then there are two cases:=20
A. MIP6 only through a private IPv4 network
B. MIP6 only through a public v4 or DS network

Personally, I'm not interested in solving scenario A and I think
it's questionable whether it makes any sense in a cellular network.
This is because it involves keepalives which pretty much eliminates
dormancy and chews battery lifetime. Others might see a need in =
non-cellular
networks, that's fine, but I wonder why not rely on any other VPN =
technology
for those scenarios. Basically, I don't see the practical need for this
solution. However, I'm not interested in blocking it.

So, _if_ there is agreement on the need for draft-wakikawa then we=20
need to be clear that it is not a complete solution. Given the absence
of a detailed scenarios discussion I feel that this discussion is =
ill-informed.=20
If there is a concensus call now, I'd vote NO. Simply because if we want
to address transition issues, this should not be the first scenario to
address. I have other comments on the way it's solved too, but this is =
not
the right email for them.=20

Hesham

Doors does something different.

Vijay,

Given the antiquated state of IETF's electronic publication technology
(early 1980's vintage), I think it makes sense to have the draft be more
self-contained. Now if we had hyperlinked documents for RFCs like the rest
of the world...

Gerardo Giaretta wrote:

- section 5.1.1, last paragraph at page 11: "In the examples shown
above, the home address of the mobile node might not be available all
the time." Are you referring to the case where the HoA is dynamically
allocated? If yes, I'd mention it at least as an example.=20
Moreover, the draft continues: "When the mobile node acquires a new home
address, it must add the address to the corresponding SPD entries." What
about the HA? Does the HA need to add the address to the corresponding
SPD entries or can it keep generic entries? I think it should add the
HoA in SPD entries.

no. if the MN initiates IKE exchange, the HA can just populate the=20
SPD from the IKE exchange. it doesnt need to create a SPD entry for=20
a specific HoA.=20

here is some new text.

    In the examples shown above, the home address of the mobile node
    might not be available all the time.  For instance, the mobile node
    might have not configured a home address yet.  When the mobile node
    acquires a new home address, it must either add the address to the
    corresponding SPD entries or create the SPD entries for the home
    address.
 

    The SPD entries on the home agent are created when the mobile node
    initiates IKE exchange.  The home agent can also have generic SPD
    entries to prevent mobility header traffic that requires IPsec
    protection from bypassing the IPsec filters.

does this look good?

Vijay

Gerardo, Keiichi, Hesham and Henrik,

draft-soliman and draft-wakikawa both talk about binding a v4
CoA to a v6 HoA and setting an IPv6 over IPv4 tunnel between
the MN and the HA. the difference is in the way, the CoA is
conveyed to the HA. draft-soliman uses IPv4 mapped IPv6
address as the source address in the inner header. I believe
the packet format looks like the following.

   IPv4 hdr (src=CoA_v4, dst=HA_v4)
   IPv6 hdr (src=v4-mapped-v6-CoA, dst=HA_v6)
   Dst opts hdr
       HoA_v6
   Mobility hdr
       Binding Update

Hesham, let me know if this is not correct?

the HA extracts the IPv4 address from the v4-mapped-v6-CoA.

draft-wakikawa uses a mobility option for carrying the IPv4
address.

   IPv4 hdr (src=CoA_v4, dst=HA_v4)
   IPv6 hdr (src=HoA_v6, dst=HA_v6)
   Mobility hdr
       Binding Update
           IPv4 CoA mobility option

this is the main difference.

apart from this, is there is anything else in draft-soliman
that you think is important for the specific scenario we are
talking about (v6 MN/MR accessing v6 HA from a v4 only access
network).

draft-wakikawa, OTOH, also talks about the following. detailed
MN and HA behavior, IPsec SPD and SAD entries for securing the
IPv6-over-IPv4 tunnel, NAT traversal, how to negotiate a
particular tunneling mechanism and new binding ack status
values.

personally, I prefer a new mobility option to carry the IPv4
CoA, because it makes processing on the HA simple. but we can
have the WG decide on this. I am open.

Vijay

Vijay,=20

I've expressed my opinion on the genreal issue before.
Regarding this topic of comparison, I don't think the=20
difference you expressed is worth writing new drafts
about. It would be much easier if you just suggest this to
us and we would discuss it. Instead, now we end up with
discussing very similar drafts for no apparent reason, which
takes more cycles.
I respect your right to write a new draft about whatever you
want. But for such a small differemce, you were welcome to
send a comment and discuss it...

FWIW I prefer not introducing a new option, the current
approach in draft-soliman fits easily within an implementation
as Conny already explained. Anyway, this is a secondary issue
and something that can be fine tuned much later in the process.

Hesham

=3D> Correct in the scenario you mentioned. This draft also
supports another scenario: using IPv4 home address and
IPv6 CoA. This is very practical if you want to use=20
MIPv6 all the time while having a DS host.

=3D> The ToCs are nearly identical with the exception of the=20
section talking about NAT traversal. This is actually not
useful in draft wakikawa. Anything that talks about NAT traveral
without keepalives is not useful. draft-soliman intentionally
does not talk about NAT traversal. The idea was that if NAT
traversal is needed it should be used optionally on top. We can
discuss reasons for that if you want.

I was saying the opposite. show me something of value from
draft-soliman that is not there in draft-wakikawa and we will
take it up from there.. :)

FWIW, we have implementations of draft-wakikawa too...

=3D> This is funny indeed, worth the smile :). So a draft comes=20
out call it draft A, then draft B comes out much later and the=20
argument for having draft B is that it contains everything in
draft A.... No I won't start from this assumption of course.
FWIW, I already mentioned that draft-soliman supports other
scenarios.

Hi,

in section 6 (and sub-sections) of draft-ietf-mip6-auth-protocol-00.txt,
you explain how an authenticator is built. The authenticator spans the Mobi=
lity
Header up to (and excluding) the Authenticator field.

As far as I understand, the MH Checksum field must be treated as zero when
calculating the authenticator because the authenticator is calculated befor=
e the
checksum. Wouldn't it be good to add a sentence on this?

Kind regards,

- Christian

My vote.

#1 Yes.

#2 No. PS is needed.  Then baseline draft can be selected or written up.

A higher-level comment, not having read the draft properly,

I don't see this as a problem as long as the list of exceptions is 
clear enough (I don't have an opinion about this because I didn't look 
closely enough).

In particular, as long as we put RFC3776 in as a normative reference, 
it's OK to just reference a section of it.  This won't become a 
problem before we want to recycle this spec to Draft Standard, but not 
move forward with RFC3776 -- and we could make the document 
self-contained then.

I happened to get across this while perusing the issue tracker.

IMHO, it would seem to make sense to add the NEMO basic support APIs 
here. As it is NEMO is already an RFC, and as it seems that the 
updates would be fairly trivial.

However, the problem here is whether the proposed NEMO APIs have been 
sufficiently reviewed by NEMO WG.  If NEMO WG chairs would say that 
there is rough consensus for these and these inclusions, this would be 
an "OK" signal for us.

What we want to avoid is adding NEMO APIs here if such would later be 
called out to not have been sufficiently reviewed at NEMO WG or 
lacking consensus there.

Obviously, all this still requires some form of approval of the AD, 
but as the document is still at AD review, i.e., hasn't been passed to 
the IESG as a whole yet, I don't think it is procedurally too late to 
kill two birds with one stone.

Hi Raj,=20

I misunderstood your question, so I take back the yes below
about the scenario. I don't see how or why you picked this=20
scenario in the first place. I do think we need a list of=20
priorities for scenarios to consider but we need=20
to do that in the context of draft-larsson which is the only
doc that lists all scenarios. Once we have that discussion
we can pick scenarios to consider for solutions.

Hello Pascal

I don't think we should exclude your scenario by this consensus call.
The mail sent by Chairs did not say exclusion of this scenario.
We look at the different scenario.

    When mobile node config new IPv6 addr by using network interface 
concat with MAC addr-EUI64 format?  Which case that mobile node can be 
duplicated because MAC addr. in LAN card was unique?
    Or this process design to protect from the faking MAC created by the 
intruder?

Whoops!  You individually may not be interested in it, but
I individually do - and I see no reason why this should be
out of scope for this discussion.

Mph.  There is quite a bit more to say about NAT traversal.
That the current wakikawa draft is under-specifying this is
putting it mildly ,:-)

1. - I agree on what you specify above, but also think this is so wide,
or general in nature if you wish, that it doesn't work as a problem
statement.

2. - I think it's premature to pick a particular document as baseline.
I don't see an agreement on a sufficiently detailed problem statement
currently, so how can we sensibly pick a particular solution?

I individually don't.
Using MIPv4 in IPv6 networks should be discussed in MIPv4 WG.

Hi Sri

my understanding is that this mechanism willnot be solo solution for
transition scenario. Your concerns are correct for some deployment
scenarios.  However, our approach is a way to solve the transition
problem and provides additional features such as less tunnel overhead
and no infrastructure supports. These features are important for
service providers.

regards,
ryuji

If there are exiting transition mechanisms and MN gets v6 address, MN
can operate without changes.  This is fine if we forget redundant
tunnel overheads.

However, what happen when a mobile node roams to just v4 networks.
Can we expect that all wireless networks will deploy with v6 or some
transition mechanism?  It makes sense that MIP6 has some way to handle
v4 address by itself (no infrastructure supports).

I got similar comments from several people. 
We'll limit one or two encapsulation types in the next version.

I'm not sure if we need an original dynamic discovery mechanism only
for this. For example, if a mobile node knows a home agent's FQDN
while in v6 network, it can also gets v4 address by DNS.

Hmm, I feel that Doors, itself, is complicated.  

My major comments to Doors are
- Doors brought security vulenerability in terms of IP header
  modification at intermediate gateways. Do we really want another NAT
  like mechanism in IPv6?
- IPsec operation is not clear to me.

> Obviously, a solution that has less constraints is easier to deploy.

You customers are not only clients using MIP6:-) 
There are also requirements such as no infrastructure support and
less tunnel overheads. I don't have customers like cisco, but I know
there are companies seeking a solution for the requirements.

Goal of Doors and our solution is cleary different. We assume
different deployment scenarios. We should not compare doors or other
transition mechanism in this thread.

Agree. I always like similicity:-)

Hello Pekka

I agree that we should not re-invent NAT traversal and encapsulation
mechanisms.  

And if this is your concern, we can simply say using IKEv2 and RFC3948
for NAT traversal and using v4-v6 tunnel for non NAT networks. We'll
use the BU/BA for tunnel end points establishment, but this is same as
MIP6. This is simple extension to MIP6 (for me).

regards,
ryuji

If there are exiting transition mechanisms and MN gets v6 address, MN
can operate without changes.  This is fine if we forget redundant
tunnel overheads.

However, what happen when a mobile node roams to just v4 networks.
Can we expect that all wireless networks will deploy with v6 or some
transition mechanism?  It makes sense that MIP6 has some way to handle
v4 address by itself (no infrastructure supports).

I got similar comments from several people. 
We'll limit one or two encapsulation types in the next version.

I'm not sure if we need an original dynamic discovery mechanism only
for this. For example, if a mobile node knows a home agent's FQDN
while in v6 network, it can also gets v4 address by DNS.

Hello Pekka

NEMO added only a mobility header option and flags for BU, BA, etc.
Therefore, modifications for NEMO can be very small.

I sent examples of NEMO APIs to Samita a while ago.
We did implement and use the NEMO APIs in KAME NEMO implementation.
It works fine. 

regards,
ryuji

Hesham and Vijay

Here is the history.
draft-heshams does not support NAT traversal, and I don't see any
solution to solve NAT traversal by using mapped address.
We will design an extension using mobility option to solve NAT issue
and throw away MIPv4 support which is not our goal in the draft.

Sorry -- this was not the point I was trying to make.  I was taking a 
procedural approach to this..

It does not matter all that much what you (as an individual) decide to 
do, or what you (as an individual) choose to implement.  Of course, 
it's nice to see there's interest and implementation of those, though. 
(Nothing against you of course personally :)

The critical thing is whether NEMO WG has reached the rough consensus 
that those modifications you (as an individual) proposed are good, and 
NEMO WG is fine with them.

For that, I guess NEMO WG chairs would need to put on a hat and take 
the sense of the "room", solicit review, etc.

That doesn't need to take long, but if we are going to add anything 
about NEMO in the spec, our AD will want us to be double-careful that 
those modifications reflect the consensus of the NEMO WG.

what i wanted to say is that we implemented both NEMO and MIP6 API.
MIP6 API is already defined and ready for RFC, but we are also waiting 
for NEMO API.

I don't think there was consensus in NEMO WG. I haven't seen discussion 
on this.
maybe better to post your initial mail to NEMO ML.

I expect that those nodes might end up running in a network without 
MIPv6 Home Agent support (e.g., a WLAN interface at home).

I assume it would be "really important" for those nodes to obtain IPv6 
connectivity (even without Mobile IPv6) in those cases as well. (This 
is because the node has IPv6 applications which it will continue need 
to support.)

So, I expect the vendors would implement IPv4-IPv6 
tunneling/transition mechanisms on the nodes as well (and this has 
already happened, e.g., look at the Symbian stack).

I do not expect that all such wireless networks deploy a transition 
mechanism, but if a node ends up in one which doesn't, it can always 
use Teredo, 6to4, a tunnel broker, IPsec tunneling or some other 
alternative to obtain IPv6 access.

However, your scenario does not really differ from here at all. 
Instead of assuming that the Home Agent is reachable from anywhere at 
all using v4 (+NAT traversal), we're assuming that a tunnel server is 
available from anywhere at all using v4 (+NAT traversal) _or_ that the 
host implements/is able to use 6to4, Teredo, or a number of other 
mechanisms.

Hence, if we don't need to restrict the solution space based on the 
encapsulation overhead, decoupling the tunneling configuration from 
Mobile IP protocols seems to make a lot of sense -- because re-using 
transition mechanisms gives you the superset of functionality.

(I'm not subscribed to nemo, sorry)

It was pointed out this should be posted on NEMO WG as well.

Does the NEMO WG want to get to the rough consensus on the APIs for 
NEMO basic support?

I happened to get across this while perusing the issue tracker.

IMHO, it would seem to make sense to add the NEMO basic support APIs here. As 
it is NEMO is already an RFC, and as it seems that the updates would be fairly 
trivial.

However, the problem here is whether the proposed NEMO APIs have been 
sufficiently reviewed by NEMO WG.  If NEMO WG chairs would say that there is 
rough consensus for these and these inclusions, this would be an "OK" signal 
for us.

What we want to avoid is adding NEMO APIs here if such would later be called 
out to not have been sufficiently reviewed at NEMO WG or lacking consensus 
there.

Obviously, all this still requires some form of approval of the AD, but as the 
document is still at AD review, i.e., hasn't been passed to the IESG as a whole 
yet, I don't think it is procedurally too late to kill two birds with one 
stone.

if you see the slides we presented at the IETF, we do emphasize
that the mechanism described in draft-wakikawa is to used only
when MIPv6 or NEMO is used. instead of setting up a MIP tunnel=20
inside a transition tunnel, we combine the tunnel.=20

I do expect the MN or MR to also implement regular tunneling=20
mechanisms. these mechanisms are used when MIPv6/NEMO is not=20
used for a particular session or if the Home Agent does not=20
support the mechanism in draft-wakikawa.

I didn't interpret Hesham's statement as being about MIPv4.
There is a separate draft (draft-tsirtsis-v4v6-mipv4-00.txt)
from the same authors which cover mip4.

However I agree that if this was the case, it wouldn't belong
in MIP6.

We covered a lot of area in RFC 3519.  You could start by
checking off the issues covered there, and how they are to be
handled.

For MIP6 there is the additional issue of how to handle various
types of NAT when you're doing route optimization - many of those
are the same as those covered quite well in
draft-huitema-v6ops-teredo-04.txt .

I expect NAT traversal to be important for MIP6 over IPv4, but I
don't expect it to be trivial.

my point was that I'd like to understand the rationale behind this
choice (is it only that it makes processing on HA simpler? how do you
measure this simpleness?). As stated before, I'm not adovacting any
draft, just trying to understand the best approach to register a IPv4
CoA. However, I think this is a secondary issue and we should address it
after we all agree on the scenario(s) to be considered.=20

| Hmm, I feel that Doors, itself, is complicated.
|=20
| My major comments to Doors are
| - Doors brought security vulenerability in terms of IP header
|   modification at intermediate gateways. Do we really want another NAT
|   like mechanism in IPv6?

Note that (but for DHAAD) the careof address is not the source address
and does not interact with the upper layer checksum. So changing the
careof is not the same thing as a NAT, by far.

Also, this happens only in the case of a NAT/PAT/RNAT on the way.
Otherwise, the CoA is not changed.

Finally, there is a threat coming from the IPv4 NAT when it is present.
The source address is changed. We have to cope with that if we find a
valid attack against the mechanism that we propose.=20

Now, Doors shows that there's value in combining MIP6 and NAT traversal
as opposed to doing them separately. MIP6 provides the keep alive and
the states (hidden in the COA), and an evolution from 6to4 provides the
gateway and the routing within the IPv6 network.

This results in a very little footprint in terms of implementation (once
you have MIP6 or NEMO to start with) and yet features like NAT traversal
... even for reverse and symmetrical NATs.

| - IPsec operation is not clear to me.
|=20

Yes. If there is to be a new version, we'll have to detail this. Then
again, the study of the risk that the IPv4 NAT introduces might be
necessary as part of the problem statement for IPv5 traversal,
regardless of the solution.

|=20
| You customers are not only clients using MIP6:-)
| There are also requirements such as no infrastructure support and
| less tunnel overheads. I don't have customers like cisco, but I know
| there are companies seeking a solution for the requirements.
|=20

The customers we have been dealing with had more addressing and routing
constraints then they had with bandwidth. The only place where bandwidth
is critical is over the radio between the MN/MR and the fixed
infrastructure using a PPP over your 2.5/3G telephone. This problem
exists today and is usually dealt with using Van Jacobson Header
Compression and RFC 1976.=20

We could easily include the MRHA header in the Van Jacobson Header
Compression. But it might be a little complex to deploy widely. Depends
on the success of MIP6 in the first place.=20

I will vote for NO at the moment.

Make I-D draft-wakikawa-nemo-v4tunnel a MIP6/NEMO WG ID:
 	For 		[  ]
 	Against 	[X]

Reasons and some random thoughts:

- I agree v4 traversal is quite important issue and see benefits in both
draft-soliman and draft-wakikawa. However, I agree to some other folks
who address a need for more discussions on target scenarios.
- I have implemented draft-soliman. From implementor's perspective,
I don't see technical difference between the methods to carry IPv4 CoA
stated in the two drafts. I would say both methods have no problem and
easy to implement. Thus, discussions of complexity wrt implementation
does not make sense, IMHO.
- Regarding the elimination of redundant IPv6 header proposed in
draft-wakikawa, I pretty much agree with the proposal. Saving 40 bytes
would greatly help us.
- I personally feel that IPv4 HoA support proposed in draft-soliman is
a strong feature that can benefit mobile users, which may accelerate
deployment of MIPv6. Note that we don't need MIPv4 signaling in such
case, but we just need small modifications to the MIPv6 stack.

Shinta

Hello Gerardo

Supporting NAT traversal or not.
For mobile node, it's simpler to clear out MIP6 tunnel and use v4-v6 
tunnel.
It also removes HoA option from packets while MN is in Ipv4 networks.
IPsec protection is also different. In our draft, MN establishes SA for 
IPv4 addresses.

what else..

Well, but it happens when MN moves to NAT network.
Most of IPv4 address which I can get in Japan is NAT address...
Do we really need address translation in IPv6 for NAT traversal..

Header compression is one way.
Compression processing cost may be burden though.
We need IPv4 traversal to use MIP6 at this point.
People said that IPv6 is deployed in japan, but not in wireless 
networks.

If we see clear scenario which we have to deal with.
Why we have to start from problem statement...

Both drafts are small modifications to MIP6.
I don't think draft-hesham is complex.
We believe that NAT traversal and less tunnelings are important.

I still think this IPv4 mobility support in IPv6 should be discussed in 
MIP4 WG.
If people use v6 applications, v4 mobility is not important.

Note that AFAIK, NAT traversal between the bidirectional MN-HA tunnel 
is likely going to be rather simple (if keepalives are considered OK 
in the scenario; as Hesham points out, they might be completely 
unacceptable in some sceanrios [but that's why it could be possible to 
turn them off it there is no NAT on the path]).

NAT traversal for route optimization would be reinventing Teredo 
(i.e., rather complex and definitely not worth the effort), but as far 
as I understand, the authors are not proposing addressing this 
particular thing.

MNs could only use the bidirectional tunnel, and if they wanted to do 
route optimization, they would have to initiate regular transition 
mechanism on the side.

Authors, is this understanding correct?

In this case, you'll come pretty close to what's covered in NAT 
traversal for MIPv4 - not complex, but a number of details to 
keep track of.  I think this work should be done.

There is no more, or less, "re-inventing" in this case than in
the MN-HA NAT traversal case, and what is required in addition, 
in order to do route optimization is probably not that much more
complex.  I think it would be a pity not to look at this, too;
but I think that the most sensible split between 'worth doing'
and 'not worth doing' might turn out be to solve this for connections
with IPv6 hosts, but not for connections with IPv4 hosts.

I think it's premature to try to pin down this as the way to go.  
(I also think it could be the wrong way to go).

but this is true also for IKEv1, just replacing Phase 1 with IKE_AUTH.
Am I wrong?
If so, I don't see any real change, only a terminology one.

okay. My issue is just that with current text it's not clear how some
requirements change.

|=20

Note that MIP has a periodic rebinding, which is the heartbeat of the
tunnel. Maybe we need some practical recommendations on how to use it in
the face of a NAT but it has a few properties, one being that it can
change overtime:

- because the MN uses a different interface
- because a network condition occurs
- you name it

In particular, in the face of a NAT, the lifetime can be adapted to be
used as a keep alive. In our tests, we usually use 30s as a lifetime, in
order to detect the MR unreachability quickly enough from the HA
standpoint. This appears to work fine with the NATs we faced.

|=20

It is true that Doors only deals with MRHA. Note that NEMO does not have
RO in the first place, so it's hard to say what it's going to be at that
point.=20

Some of the proposed NEMO RO schemes have to do with nested NEMO, and
that much can be all IPv6. Others happen fully in the IPv6
Infrastructure (as opposed to end to end) and could be limited to the
fully IPv6 part of the way...=20

 I'm not sure to well understand this part. 
 Do you mean that the home agent creates the SPD entries for the mobile
 node after receiving the first IKE packet ?

Based on rfc3776 and draft-ietf-mip6-ikev2-ipsec-01, the SA must be
created for the HoA, that is always an IPv6 address in your scenario.
So, what do you mean by "MN establishes SA for IPv4 adresses"?

Hi Hesham:


Since the subject was dormant for a long time, Doors was not updated,
maybe since you last read it :) To answer your question, we saw that
there are a few operations associated to NAT traversal. In the context
of doors:

a) as we said, keep alive, which doors associates with the BU lifetime.
We have a BU lifetime, the question is the duration, and whether we can
afford to turn it to a relatively low value in order to keep NATs
active. The MN has heuristics to select a roaming interface, and the
cost/bandwidth of that interface is used in that computation.=20

After that, it's the node's policy: If the MN really wants to connect
and the only solution is via a NAT, or simply if it's the best way for
its seletion algorithm, then it'll pay the cost of a short lifetime and
go via the NAT.

b) MN operation: it restores its CareOf from the IPv4/UDP headers. Just
a few memory copies. The MN can see both the private and the public
addresses and ports being used, and compute whether they were NATed by a
simple comparison between those.

c) Doors gateway operation. Same, plus a specific operation on DHAAD
since the upper layer checksum is impacted by the CareOf modification.

~d) There's no impact on the HA or on the MIP6/NEMO protocol being run.
As Pekka says, Doors is not a MIP modification but yet another automatic
tunneling mechanism, that takes advantage of existing MIP6 mechanisms
and states.

Out of all this, there's nothing much to turn off. I'd say it automatic.
The lifetime adjustment is a MN algorithm based on its config and
policy. Same for accepting a NAT on the way.

Pascal

draft-wakikawa specifies one mechanism to detect NATs based=20
on IKEv2. and the NAT traversal mechanism can be used only=20
when a NAT is detected. see the draft. so for local mobility,=20
for e.g. if no NAT is detected between the MN and the MAP,=20
NAT traversal is not used. if a NAT is detected between the=20
MN and the HA, NAT traversal is used.

we have two options for NAT traversal. if all traffic through=20
the tunnel is protected by ESP, then we use RFC 3948. if ESP
is not used, then IPv6-in-UDP-over-IPv4 tunneling is used.

and in the slides we presented at the IETF, we had a question
for the WG, if we need to come up with another NAT detection
mechanisn based on MIPv6 (similar to what MIPv4 does), but
we didnt get any response. if the WG thinks we need one based
on MIPv6, I have an idea on how to do it.

Sure. The problem you are trying to address and what the doors draft
is addressing is not totally different, just the constraints are
different. It is better if we first agree up on the problem and
look at all these solutions in perspective.

Not sure, if I understood what you mean by "turn of NAT traversal".
NAT traversal is based on the need. Doors applies some what
similar to 3519 NAT detection logic.

We plan to revise the Doors draft and clarify text where ever needed.

It is a procedural decision. So far the decision by MIP6 chairs is to move 
forward with
the MIP6 document without the NEMO changes, and NEMO changes would go on
a separate doc. when they are ready. 

Personally, I am OK with whatever makes best sense for the MIP6 community
without too much delay of the MIP6 API document, as it is quite ready and
well discussed in the MIP6 wg.

Regards,
-Samita

No. I assume that the scenario we are talking about is based on
assumptions that HA and MN are dual stack nodes and only IPv6
is included as target of mobility support. I am personally OK with
the assumption on network model. However I don't agree with the
latter one.

The reason why I think MIP6 WG should not exclude IPv4 HoA
support is that it simply helps MIPv6 to deploy. OTOH, I do not think
that MIP6 WG should discuss running MIPv4 in IPv6 network. That
should be discussed in MIP4 WG. I clearly see the difference between
the two cases. What do you think?

 In your previous mail you wrote:

   I have some comments on draft-ietf-mip6-ikev2-ipsec-01.
   
   Overall, the draft looks good. In my opinion, the unique general issue
   is that it is tied very much to rfc 3776 and as a result it is not
   self-contained. I mean that it is not possible to read the draft without
   having also rfc3776 in front of you. This is ok to me, but I wonder if
   it is acceptable in general.
   
=> as the 2401bis is deeply different, for instance it has a syntax
for SPD entries, IMHO the document should be rewritten from scratch
(and if possible by an IPsec person, ideally someone who participated
to 2401bis/IKEv2 development).

   Some more detailed comments:
   
   - section 3.2, bullet 3: maybe I am missing something here, but how this
   is different from IKEv1 and rfc 3776?
   
=> there is a wrong lower case should in place of the MUST for using
the care-of address as the source address of packets.

Regards

Francis.Dupont@enst-bretagne.fr

PS: I still believe the document goes to the wrong direction, for instance
requiring support for MH type selectors when it is expected than the
common policy will be to protect all the packets on the MN-HA tunnel
(better for privacy, simpler, and easy to implement by BITW).
Another issue is the total lack of implicit or explicit references to
the pki4ipsec work...

Chairs: Basavaraj Patil and Gopal Dometty

Minutes provided by: Suresh Krishnan

Agenda bashing
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Alper: wants to change the order of item 4 and 5 since framework needs =
to be=20
covered before the solutions. Patil: Thinks the order is fine as 4 is =
very=20
specific and will not be affected by the choice of the framework

issues working with cairs and ADs

AD evaluation comments pointed out that a clearer applicability =

Vijay presenting

A whole bunch of requirements have been relaxed=20
-> Support for Peer Authorization database, HoA configuration and EAP =
changed=20
to MAY
-> Clarified that there is no need to use public key mechanism to =
authenticate=20
HA if the chosen eap method already is mutual.

Open Issues:

SA for the BU is not created until the first CREATE_CHILD_SA (requires 3 =
rtt rather than 2rtt)

SPD entries and dynamically allocated HoA (SPD uses HoA)
3 options
  -> update SPD when the HoA changes
  -> reinstall policy entries when the HoA changes
  -> use a name in SPD and have name point to HoA

Jee wants a clarification about use of preshared keys as the method. =
Jari talks
about adding a reference to a draft Hannes and Pasi have written about =
not=20
needing to use PK when EAP mutual authentication is used.He also =
mentions that
the draft has no home currently. Vijay will add the reference

mip6 AAA framework
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Alper presenting

The goal of the draft is to identify various frameworks where AAA is =
used=20
for mip6 service and agree on one or more to standardize

Alper talks about 4 different frameworks and the characteristics of each

Framework 4
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Jee  is concerened about preconfiguring the HA address and thinks =
dynamic=20
assignment of HA is very important. Alper will talk about it later.

Framework 2
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Vijay wants to know how DHCP server know which domain the MN belongs to?
Alper thinks that it is immaterial. Will use DHCP ID to correlate

Vidya wants to know what happens if the NAS and HA do not belong to the =
same=20
domain as the NAS shares SA only with AAA-L(visited)? Greg thinks that =
this can
work transparently as there is a transitive trust rel between AAA-L and =
AAA-H
Raj has the same view as Greg. Gopal wants to add info about AAA-H and =
AAA-L.

Framework 3
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Jari wants to know how MN can know CoA and HA before initiating the =
procedure.
Greg thinks that there is no need to know as the AAA can do the BU
James wants to know how the AAA server can know where the prefix is.Greg =
thinks
that it will come from the NAS. Alper thinks that this framework is =
workeable=20
but complex.

There are three requirements for a solution to fulfill. HA discovery, =
HoA=20
discovery, and MN-HA key generation

Hannes and Alper talk about how these frameworks can be mix-n-matched=20
to satisfy these requirements

Jari is concerened about the impact caused on network since the goal is =
to=20
reuse the exisiting AAA relationship. Client software, DHCP and NAS need =
to be=20
updated to implement these solution.

Summary:
Framework4: requires new aaa-mip6 application
Framework1: requires confirmation from ip conf sec bof
Framework2: needs new AAA attributes and PANA/DHCP options (*3gpp2 =
prefers this approach)
Framework3: Very complex and may not be justifiable

Alper wants direction from the WG to know which way to go. Gopal wants =
people=20
to read the drafts and discuss on the ML

MIP6 Bootstrapping
james kempf presenting
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Tries to address situations where loose trust between serving network =
access=20
provider and Mobility Service Provider(MSP).e.g. enterprise networks,=20
hotspots (As most of them use Credit Cards to authorize and not AAA), =
and for=20
infrastructureless deployments very well)

John thinks that UAM (universal access method) is popular now but there =
are=20
still backend AAA networks. He also thinks that 802.1x means more and =
more=20
RADIUS as UAM does not work on small devices. James believes that CC =
based=20
authentication is not going away and we need to support it. Jari thinks =
that
this method does not fit a mobility scenario since the CC based =
authentication
is used maily for wireless nodes in hostpots (usually immobile).

The basic idea is for the MN to ask for DNS SRV records a to get the HA =
address
Then IKEv2 is used to extablish MN-HA keying. Replay protection provided =
by=20
Message identity code in DNS (RFC1035) and data integrity and origin =
auth=20
provided by DNSSEC.

Alper wants to know how the HA will authenticate the MN. James thinks it =
will
be preprovisioned credentials like EAP username/password, preshared keyz =
etc.
Alper is concerned about sharing the HA address with external networks.=20
James is not worried even though DNS has no authentication. He also =
clarifies
that this is meant to be used in the absence of RADIUS=20
Raj is worried about DNS caching HA address. Thomas is also concerned.=20

Hannes wants to decouple the two problems addressed in the draft 1) use =
IKEv2
for bootstrapping and 2) use DNS for discovery. He also suggests the=20
possiblity of using multi hop PANA

James wants to use DNS TSIG (RFC2845) for protecting HA addresses. =
Thomas
thinks that nobody needs this. James thinks that if addresses are hard =
to get
it makes DoS harder. Thomas thinks that James is very unclear. He wants =
to know
what is really being protected. MN from bogus DNS replies or the DNS =
server=20
from bogus DNS requests? James says both scenarios are protected againt.
Samita clarifies that DNSSEC is not deault and is optinal.=20
Raj thinks this makes DOS attacks easier Thomas disagrees and states =
that he
likes this solution. This is nice and simple instead of the other =
complex=20
solutions. He likens publishing the HA address to Wells Fargo =
advertising its
1-800 Number.

Goals for AAA-HA interface:

Gopal wants to know if the goals are related mainly to bootstrapping.

koodli-mip6

Intro- specific scope for MIPv6
HOa - visible in all packets the MN uses it home or visited network
COA - visible at visited networks

Problem

Hoa COA could be profiled for activity
COA reveals roaming of a mobile node node when HoA is used

Profile:
 -can use privacy ext, to IPv6 (rfc3041)
- Can introduce additional MIP6 signalling ( when coa changes )

Profiling problem

Using 3041 introduces DNS and IPSec considerations

DNS , IPsec (rekeying for change in Hoa)

Roaming problem
 - reverse tunnel data packets (to solve COA problem)

Privacy Label Computation
Don't send HoA in the BU in the clear - use in label
Label should be computable without the knowledge of HoA

Mobopts will discuss this initially and similar other proposals.
It will be adopted by MIpv6 wg.

ipv4 traversal for mip6 protocols

=3D=3D=3D=3D=3D=3D=3D=3D
Vijay presenting

This is useful if the MN lands on v4 only network.
The MN registers ipv4 address as CoA using a new mobility option
and can setup all types of tunnels. 6 over 4, ESP, UDP etc. use same=20
mechanism for mip6 and nemo

Is there interest to do this in the wg?

Gopal thinks that we should discuss this for the next IETF. Greg thinks =
that=20
it looks interesting. He thinks we should have a bar bof.(Not just =
looking to get to the bar, he says)

Raj wants to know if the wg should work on location privacy:
(CONSENSUS CALL)
yes? about 30 hands
no? no hands
(CONSENSUS IN FAVOR)

Next steps for WG
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Gopal presenting

-> Address AD/IESG comments on auth option

-> Bootstrapping solution
solution ID by next IETF.=20
Close design team shortly after next IETF
last call and IESG by IETF64

-> mip6 transition issues
Gopal wants an ID to document transition issues
Vijay thinks it is a bad idea to write an all encompassing problem =
statement.
Raj and Gopal agree with Vijay. Thomas thinks that this problem has been =

around for long and v6 v4 transition issues should be documented by =
someone=20
who ACTUALLY has a problem. Otherwise we will have a huge problem space
Gopal wants to define the problem space to be as narrow as possible. =
Thomas=20
wants to agree on the scope of the problem before solving it

->work with mobopts to define and suggest privacy solutions
->propose revision to milestones

Rajeev wants to know the timeline for the mobopts work. Gopal mentions =
that
it should be done before the next IETF.


mobile firewalls
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Qiu presenting

The idea is for the HA to control the activities of the MN in a visited
network.

Raj wants to know if this is applicable only with HMIP. Qiu says it is. =
He also
mentions that it is a scenario to illustrate out a general scheme.

PF_KEY between mipv6 and ipsec
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D
Shinta presenting

MIP6 uses IPSEC to protect signalling messages. SA pairs need to be =
established
and tunnel mode SAs need to be updated when the CoA changes. MIP6 may =
not have
direct access to the SADB.
Defines a new PF_KEY message called MIGRATE
PF_KEY MIGRATE requires update of SAD and SPD
This has already been implemented

Vijay thinks this is very good work. Hannes has worked on a similar =
document=20
which is more generic and wants a slot to talk about it

(OUT OF TIME)
Raj mentions a draft from James/Vijay about HA unavailable message which =
is=20
sent when a HA is going down. It needs to be discussed in the ML

the MN cant use anything other than CoA as source address of IKE
exchange. so why is there a need for a MUST? thats the only way
to do it.

the MN can always negotiate SAs so that all traffic is sent through
the MN-HA tunnel. but I find it wierd not to take advantage of
the additional selectors provided by 2401bis. it is better for privacy
I agree. see section 2.1 of
http://www.ietf.org/internet-drafts/draft-koodli-mip6-location-privacy-solutions-00.txt
but that shouldnt be the default mode, IMHO.

what should we be in specific referring to? to
draft-ietf-pki4ipsec-ikecert-profile or to some section in it?

yes. in the case of a dynamically assigned/auto-configured home
address an SPD entry for a specific home address is created only
when the HA gets to know about the home address of the MN. the
HA itself could be allocating the home address during the IKE
exchange.

   the MN cant use anything other than CoA as source address of IKE
   exchange. so why is there a need for a MUST? thats the only way
   to do it.
   
=> so we agree the draft should be fixed.

   the MN can always negotiate SAs so that all traffic is sent through
   the MN-HA tunnel. but I find it wierd not to take advantage of
   the additional selectors provided by 2401bis.

=> I am not against to take advantage, only to make this mandatory.

   it is better for privacy
   but that shouldnt be the default mode, IMHO.
   
=> I agree, the default mode should be the same than in 3776, i.e.,
MH protocol as the selector. But the two others (all traffic and only
the critical MH types) have to be allowed.

   > Another issue is the total lack of implicit or explicit references to
   > the pki4ipsec work...
   
   what should we be in specific referring to? to
   draft-ietf-pki4ipsec-ikecert-profile or to some section in it?
   
=> IMHO the most of the text is relevant, for instance 3.1.1
   o  the administrator intends the implementation to verify that the
      peer source address matches the IP address in the ID received, and
      that in the iPAddress field in the peer certificate's
      SubjectAltName extension.
...
   In addition, implementations MUST be capable of verifying that the
   address contained in the ID is the same as the peer source address,
   contained in the outer most IP header.  If ID is one of the IP
   address types, then implementations MUST perform this verification by
   default.  If this default is enabled, then a mismatch MUST be treated
   as an error and security association setup MUST be aborted.  This
   event SHOULD be auditable.  Implementations MAY provide a
   configuration option to (i.e.  local policy configuration can enable)
   skip that verification step, but that option MUST be off by default.
   We include the "option-to-skip-validation" in order to permit better
   interoperability, as today implementations vary greatly in how they
   behave on the topic of verification of source IP.

So in your draft section 5.2 the first option should not be recommended
(i.e., it should be used only when the two (and far better) others are
not available).

   yes. in the case of a dynamically assigned/auto-configured home
   address an SPD entry for a specific home address is created only
   when the HA gets to know about the home address of the MN. the
   HA itself could be allocating the home address during the IKE
   exchange.
   
=> IMHO the verb "create" is too strong because an SPD entry can exist
without addresses (addresses are only a form of selectors), quoting
2401bis draft:

      - Name:  This is not a selector like the others above.  It is not
        acquired from a packet. A name may be used as a symbolic
        identifier for an IPsec Local or Remote address. Named SPD
        entries are used in two ways:

         1. A named SPD entry is used by a responder (not an initiator)
            in support of access control when an IP address would not be
            appropriate for the Remote IP address selector, e.g., for
            "road warriors."  The name used to match this field is
            communicated during the IKE negotiation in the ID payload.
            In this context, the initiator's Source IP address (inner IP
            header in tunnel mode) is bound to the Remote IP address in
            the SAD entry created by the IKE negotiation. This address
            overrides the Remote IP address value in the SPD, when the
            SPD entry is selected in this fashion.  All IPsec
            implementations MUST support this use of names.

I believe we are in this case (and note its support is mandatory) even
in the real world one can't see the difference with your proposal.

We don't need IPv6 NAT but we're imposed NAT when v6 traverses v4 
networks...

Yes, and securing this excludes IPsec, and can only rely on tokens in 
UDP messages, eventually within the non-BU keepalives.

Isn't header compression a non-end-to-end feature?  I thought HC happens 
only between the terminal and the first hop.  So if the requirement is 
not to touch the v4 network (just traverse it) then HC is no use.

Yes, but how?  When you say "will fix this" and give no detail or 
potential idea about how this could be done, it sounds like you already 
know how to do it and not care very much about the scoping or 
requirements (that don't yet exist anyways).  I may be wrong with my 
interpretation of "will fix this" - sorry - but that's what it sounds to 
me at this second affirmation.

Vijay, thank you for posting this.  My headers for v4-traversal for MIP6 
look like this:

 >   IPv4 hdr (src=CoA_v4, dst=GW_v4)
 >   UDPv4 (src port, dst port)
 >   IPv6 hdr (src=v6-CoA, dst=HA_v6)

The src of the v4 header and the src/dst ports change if NAT is present.

For v4 header compression, sure. (But very constrained environments 
probably employ v4 and UDP HC on their own in any case).  HC for v6 
headers is still possible without touching v4 network, of course.

Ryuji, how are you going to design this extension with a mobility
option?  I know of a NAT that blocks all IP-in-IP and as long as the
mobility option is deep below IP it's going to be of no use.

MIP4 has a nice feature for NAT traversal, that I know implemented. 
That feature could be re-used.  I don't understand why you would throw 
it away and design a new option in the mobility header?

MIP4 has NAT traversal based on UDP, which could be used for MIP6 too.

Vijay, I'm not sure NATs need to be detected.  I'm not sure it's 
necessary to impose the use of IKEv2 in order to detect being behind a NAT.

Being behind a NAT or not can be detected very simply by the GW by 
checking the src address and some address that MN puts in the payload.

I kind of agree with this.  I was thinking though that if the outer v4 
packet is not ESP'ed then the inner v6 packet could be ESP'ed, or 
alternatively - if UDP tunneling is used - RFC 3948.  At which point it 
would make no sense to use both RFC 3948 _and_ RFC 3776, because that 
would give double ESP encapsulation...

How?

That assumes that you have a separate signalling plane (e.g., MIPv6 
binding updates) apart from the data plane. You also lose at least 1 
RTT for signalling.

However, if the client knows in advance which encapsulation type to 
use, it can just send in a request, piggybacking the data, and if the 
tunnel is set up, the tunnel server can immediate forward the data and 
set up the tunnel, otherwise reject setting up the tunnel and discard 
the data.

One 1.5 RTT's vs 0.5 RTT to forward user's packets and some amount of 
protocol complexity may not be an issue, of course.

Yes, a separate signalling plane.

Yes, but it's impossible to just send an enhanced BU to HA without first 
setting up some state on GW and MN about the v4/NAT traversal.  The 
state on MN, NAT and GW must be synchronized somehow and doing it with 
only one message MN->NAT->GW is impossible, I mean some acknowledgement 
is necessary.

To this scenario I object with the security aspects.  If the tunnel 
server puts up a tunnel whenever a Client requests it, and if they don't 
share a secret, DoS attacks are obviously possible.

I'm not sure what you mean.  MN can send a message directly to the HA 
(or tunnel server, if applicable), going through the NAT; this also 
(implicitly) punches a hole in the NAT.  The HA (or tunnel server) 
naturally acknowledges the set up of the tunnel, but if the 
acknowledgement comes from the same UDP port (etc.), it will use the 
already established NAT state.

Obviously the client can include whichever secret it wants.  Too bad 
0.5 RTT doesn't allow a challenge-response negotiation, so it's 
effectively a shared, plain-text secret.

There are other options, though.  See 
draft-parent-v6tc-protocol-exploration-00 section 2.1.2 for an example 
how SEND could be used in this context securely without any extra 
roundtrips.

But this discussion is probably going to too much detail at this 
point, so I guess we should take the followups off-list(s).

YEs... somehow... "Punching" a hole in the NAT boxes may not be 
immediately successful, several probes may be necessary, in which case 
the successful probe's characteristics should be acknowledged back to 
the MN in order for it to know what to use starting then.

Alex,

there are multiple ways of doing this. thats why I havent
mentioned how we will fix this. infact, the WG can decide
on this. we will get to that later.

infact, if UDP encapsulation of IPsec packets is used as
described in RFC 3948, (see section 9 of draft-wakikawa),
we *don't* need to specifiy anything. RFC 3948 already
specifies a NAT keepalive mechanism

somebody mentioned dummy ICMP messages. others mentioned
sending binding updates now and then. both should work.

Vijay

Alex,

I think you misunderstood what Ryuji sent. we do plan to
use UDP encapsulation if a NAT is present. nobody is
throwing that out.=20

Ryuji was talking about the scenario where a mobile binds
a IPv6 CoA to a IPv4 HoA. he saying he is not interested
in this scenario.

Sorry to misunderstanding Ryuji.  I think v6-in-UDPv4 should be used
independently of NAT being used or not used.  Whether I misunderstand
anybody with this - it's your call.  All I want to say is that this
aspect (use IPv6-in-UDPv4 independently of NAT/no NAT) should be considered.

Me too I'm not interested in this particular scenario here and today.
But I am interested in MIP4 using UDP for NAT traversal and MIP6 using
the same UDP tunnel.

And I'll take the remark from Pekka into account here - maybe it's too 
early to discuss these solution technicalities.  In this case let's see 
about scoping and requirements.

okay. infact, using UDP all the time is quite popular (even my
corporate VPN access uses UDP tunneling all the time). but we
shouldnt specify that UDP tunneling should be on all the time
in an IETF standard. if a NAT is not there (being optimistic),
we dont want the additional per-packet overhead.

I still believe the document goes to the wrong direction, for instance
requiring support for MH type selectors when it is expected than the
common policy will be to protect all the packets on the MN-HA tunnel
(better for privacy, simpler, and easy to implement by BITW).

-----------------

the default mode should be the same than in 3776, i.e.,
MH protocol as the selector. But the two others (all traffic and only
the critical MH types) have to be allowed.

.=2E.
   In addition, implementations MUST be capable of verifying that the
   address contained in the ID is the same as the peer source address,
   contained in the outer most IP header.  If ID is one of the IP
   address types, then implementations MUST perform this verification by
   default.  If this default is enabled, then a mismatch MUST be treated
   as an error and security association setup MUST be aborted.  This
   event SHOULD be auditable.  Implementations MAY provide a
   configuration option to (i.e.  local policy configuration can enable)
   skip that verification step, but that option MUST be off by default.
   We include the "option-to-skip-validation" in order to permit better
   interoperability, as today implementations vary greatly in how they
   behave on the topic of verification of source IP.

So in your draft section 5.2 the first option should not be recommended
(i.e., it should be used only when the two (and far better) others are
not available).

hmm... if there is only one way to do it, do we need a 'MUST' to
talk about it. if there are multiple ways of doing it and we
want interoperability, then we should be using a MUST. anyway,
this is what we have currently.

    o  The mobile node should use its Care-of Address as source address
       in protocol exchanges, when using dynamic keying.  However, the
       security associations MUST be created for the home address of the
       mobile node.

you want it changed to the following?

    o  The mobile node MUST use its Care-of Address as source address
       in protocol exchanges, when using dynamic keying.  However, the
       security associations MUST be created for the home address of the
       mobile node.

okay. atleast we agree that the tunnel mode shouldnt be the default.

I agree. infact the entire section 3.1 is relevant because many
times the identification presented in the IDi payload might be NAI
or FQDN.

I propose adding the following to section 5.2

    When PKI based authentication is used between the mobile and the Home
    Agent, the identity presented by the mobile node in the IDi payload
    must correspond to the identity in the certificate obtained by the
    Home Agent.  The Home Agent uses the identity presented in the IDi
    payload to lookup the policy and the certificate that corresponds to
    the mobile node.  If the mobile node presents its home address in the
    IDi payload, then the Home Agent MUST verify that the home address
    matches the address in the iPAddress field in the SubjectAltName
    extension [9].

    [9]   Korver, B., "The Internet IP Security PKI Profile of
          IKEv1/ISAKMP, IKEv2, and PKIX",
          Internet-Draft draft-ietf-pki4ipsec-ikecert-profile-03, October
          2004.

if you are not happy with this, please propose some text.

Francis, I dont think we can mandate that somebody use PKI instead
of shared secrets through IETF specs. deployment considerations
determine this. not us. I do agree that if PKI is available it
should be used. maybe we can emphasize that PKI be used if available.
would that be enough?

Hi Vijay:

I would not approve a solution that makes a dependency to IKEv2 for
traversing NATs, unless IKEv2 becomes universal for MRHA. At the moment,
the relation between the key negotiation and IPv4 traversal mechanisms
seems pretty loose so I would not forcefully tie them, even if it
actually works.

I'd rather have a modular approach in the solutions that we put in place
for the problems that we want to solve.

But maybe I missed what you really mean here. Could you clarify?

Pascal

Hi Vijay:

| Being behind a NAT or not can be detected very simply by the GW by
| checking the src address and some address that MN puts in the payload.
|=20

This seems to omit reverse NATs where the HA is actually within an IPv4
private network, which is a case that we face in small/medium
corporations which can not afford a DMZ. That's also the simplest way
for me to set it up at home so I can keep my DSL connection the way it
stands.

So maybe it's time to discuss what the NAT traversal requirement is. The
way I see it, we need to go through NAT, PAT and reverse NAT. In other
words, MR encapsulates an IPv6 packet into IPv4 UDP. Any of (IPv4
source, IPv4 destination, UDP source port) might be changed. IPv4
destination port should be standardized to avoid confusions.

I think both cases are valid but only the direct (non-reverse) NAT can
be done with my implementation.  Traversing a pair of NAT and reverse
NAT induces a need for a box outside both domains that would need to be
standardized.  At this point I think it would be an unncessary burden.
I think.

Only the source address and the src/dst ports may change, but not the
dst address.  I would agree with this requirement.

Ok but standardizing an IPv4 destination port does not mean that a
firewall filter will not block it.

 In your previous mail you wrote:

   you want it changed to the following?
   
       o  The mobile node MUST use its Care-of Address as source address
          in protocol exchanges, when using dynamic keying.  However, the
          security associations MUST be created for the home address of the
          mobile node.
   
=> OK for me.

   okay. atleast we agree that the tunnel mode shouldnt be the default.
   you want it explicitly mentioned in the draft?
   
=> I don't believe the word default is necessary: IMHO we should just
present things in the right order and explain there are two alternatives
to the selector = MH protocol.

   > the default mode should be the same than in 3776, i.e.,
   > MH protocol as the selector. But the two others (all traffic and only
   > the critical MH types) have to be allowed.
   
=> in fact any selector set which provides the right protection should be
allowed... The two alternatives need to be detailed because they have
some advantages so should become common. Of course both sides should
agree before.

   > So in your draft section 5.2 the first option should not be recommended
   > (i.e., it should be used only when the two (and far better) others are

   Francis, I dont think we can mandate that somebody use PKI instead

=> I agree we may not put a "MUST" but this is a good place to play
with SHOULD and MAY with a good explaination.

   of shared secrets through IETF specs. deployment considerations
   determine this. not us. I do agree that if PKI is available it
   should be used. maybe we can emphasize that PKI be used if available.
   would that be enough?
   
=> we agree about the target.

Pascal,

RFC 3775, 3776 and 3963 all use IPsec by default for
setting up security associations between the MN/MR and=20
the HA. once draft-ietf-mip6-ikev2-ipsec is approved, I=20
believe IKEv2 will become the default mechanism for=20
setting up security associations between the MN/MR and=20
the HA.

so what are you objecting to? the use of IKEv2 or the use
of IKEv2 for detecting NATs?=20

IKEv2 has a NAT detection mechanism. and if MN/MR and=20
the HA use IKEv2 to set up security associations, then it
is natural to use IKEv2 to detect NATs also.

if the WG feels we need another MIP specific mechanism
for detecting NATs, we can work on it. we had that=20
question on the slides presented at the last IETF meeting.
there wasnt any feedback at that time.

Vijay

Vijay, excuse me interfering in your discussion with Pascal.

Thanks for posting this, it is important to remind that all Mobile IPv6 
RFCs rely on IKE to set up the MN-HA SAs.  I must also say that I am not 
very familiar with IKE, and even less with IKE's NAT detection features 
and nothing about IPv6 IKEv2.

ALso, please let me point out that if IKEv2 for v4 is capable of going 
through all sorts of NATs, and if using IKEv2 for v4 does not involve 
exchanging too many messages every time MN changes its v4 Address, then 
I think I support it, instead of MIP4's NAT traversal scheme.

However, may I also say that the ISAKMP (that I use with my corporate 
VPN, probably similar to yours) (1) uses a 10-message initial exchange 
and (2) uses a fixed outgoing port number for UDP which seems to be 500.

Shortening the 10-message exchange is probably seen by you to be done 
with RFC3776  or with draft-ietf-mip6-ikev2 (I'm not sure); but both 
these drafts are v6-related; or, the NAT traversal should be v4-related, 
and I am not aware of a requirement to use IKE between MN and HA for 
MIP4, neither am I aware of a way to shorten the 10-message v4 IKE 
exchange.  Enlightenment on this issue would be beneficial.

For the second issue (UDP port 500) I am not sure that all wireless 
telecom operators let through this particular port number (and if they 
do, do they without translating the port number?), hence the potential 
need to scan for open ports.  When connecting to a particular wireless 
telecom operator with my corporate VPN, it won't get through even if I 
set the flag "NAT present", even the flag "use port 80".

Can IKEv2 for v4 help with this issue?  Does IKEv2 for v4 has any 
reputation of going through all sorts of NAT/NAPTs?

If an implementation of IKEv2 for v4 is able to do this, then I'm fully 
supportive of it.

Alex

Vijay,
If other mechanisms such as the AUTH option are standardized, and if IKEv2 is not used to set up the SA between MN/MR and HA, a solution for NAT traversal that has a dependency on IKEv2 will have a problem. Given that this is a possibility, do we really want to make this the solution? 

In my mind, it is fine to use IKEv2 to detect NATs when it is used - but, it doesn't seem to me that we can assume it will always be used? 

I somehow didn't raise it at IETF, but nevertheless, seems important to discuss :) 

Vidya

Pascal,

RFC 3775, 3776 and 3963 all use IPsec by default for
setting up security associations between the MN/MR and 
the HA. once draft-ietf-mip6-ikev2-ipsec is approved, I 
believe IKEv2 will become the default mechanism for 
setting up security associations between the MN/MR and 
the HA.

so what are you objecting to? the use of IKEv2 or the use
of IKEv2 for detecting NATs? 

IKEv2 has a NAT detection mechanism. and if MN/MR and 
the HA use IKEv2 to set up security associations, then it
is natural to use IKEv2 to detect NATs also.

if the WG feels we need another MIP specific mechanism
for detecting NATs, we can work on it. we had that 
question on the slides presented at the last IETF meeting. there wasnt any feedback at that time.

Vijay

yes. this is a valid issue. I am fine with developing a
MIP specific mechanism for NAT detection in addition to
IKEv2.

James, 
Yes, my question was if it were to be standardized... Also, there are many mechanisms being discussed for the MN-HA SA creation, some of which are not based on IKEv2.

IKEv2 is version neutral. I believe the same mechanisms work
for both v4 and v6.

yes.

for what I understand, the same two round trips that IKEv2 takes
always. somebody correct me if I am wrong.

atleast IKEv1 seems to work with most NATs. IKEv2 should work too.
but in general, this is a very difficult question to answer. I
believe not all NATs behave in the same way. we have a WG in the
IETF, BEHAVE, which is trying to figure what is a standard behavior
for NATs. :) http://www.ietf.org/html.charters/behave-charter.html

draft-wakikawa explains running IKEv2 between MN/MR and HA when
the MN/MR are on a v4 only access network. the MN uses its v4CoA
as the source address in the IKE negotiation. the negotiation is
done with the v4 address of the HA. the final security associations
are created between v6 HoA and v6 address of the HA.

I tried to use the same terminology adopted in the problem statement
draft in order to keep them coherent. This is the definition of trust
relationship in the last version of PS draft:

   Trust relationship
      In the context of this draft, trust relationship means that two
      parties in question, typically the user of the mobile host and the
      mobility or access service provider, have some sort of prior
      contact in which the mobile host was provisioned with credentials.
      These credentials allow the mobile host to authenticate itself to
      the mobility or access service authorizer and to prove its
      authorization to obtain service.

Which are your concerns with the usage of this terminology in these
drafts with regards to this particular definition?=20

I guess there is still space to change the mip6 bootstrapping problem
statement document. Alpesh is still working on it.
It seems that this issue is mainly related to mip6 bootstrapping PS
draft. My idea for draft-giaretta-mip6-aaa-ha-goals is to keep the
terminology of the PS draft. So, no problem for me to change the
terminology here but only if it is changed also in the PS draft.

>=20

Scenario 4 is not related to dynamic bootstrapping. The point is:
suppose the MN is statically provisioned with the HA address and the HoA
and has a manually configured SA with its HA. In this scenario, how do
you perform the authorization procedure? The location of the MN (in the
sense that it has moved to a new location and got a new IP address) was
just an example; another could be the time of the day or whatever else
can be in the user profile.

Do you think that this scenario is not to be considered?=20

>=20

The assumption in the draft is that there is a one-to-one matching
between the user and the MN. Do you see a possible issue in identifying
the user/MN with the NAI in the communication between the AAAH and the
HA?

>=20

The HA is an anchor point, at least for bidirectional tunneling. For
this reason an operator might want to install policies on MN's traffic
exploiting that all bidirectional data is tunneled through the HA.

>=20

This is mainly related to scenarios 3 and 4. The HA, after receiving a
BU or during the IKE exchange, could get in touch with the AAAH in order
to authorize the user. Based on the response from the AAAH, the HA can
grant Mobile IPv6 service to the MN.

This might also be relevant for scenario 1. However, in this case the
AAA-HA communication is used also to authenticate the user.

>=20

I think you are referring to goal G2.7.

"
G2.7	The AAAH server should be able to retreive the Mobile IPv6 state
associated to a specific MN from the correspondent HA. This may be
useful to periodically verify the Mobile IPv6 service status.
"

Suppose that the AAA architecture of the MSA/MSP is stateless and the
AAA server that handles MN re-authentications changes over time. If
bootstrapping is performed during network access, how the AAA server
knows that the MN is already registered with that HA? A possible
approach could be: the MN tells the AAA infrastructure that it is using
a particular HA and the AAA server verifies the MN's state on that HA.
See draft-giaretta-mip6-authorization-eap-02, section 5.2 for details.

this goal is related to scenario 2. The MIPv6 bootstrapping is performed
during network access authentication communicating with the AAAH. In
this case the MN does not communicate directly with the HA. For this
reason, it is the AAAH that has to send the HoA to the MN. As you
mention one possibility is that the AAAH selects one HoA by its own.
However, my idea is that it is better that the HA allocates the HoA
since it has the most updated vision on the addresses allocated in its
link (e.g. it could have a list of HoAs already taken).

As mentioned above, the AAAH sends the HoA to the MN in scenario 2, but
the HoA is selected by the HA.

This refers to:
- PSK for IKEv2
- PSK and peer authentication method for IKEv1 Phase 1

Moreover, we'd like to keep the requirements a bit general in order to
address also mip6-auth if it will be necessary.

agree. Different for IKEv1, though.

could you please elaborate this point? don't you think this is more

                           May, 30-31, 2005

The Second IEEE Workshop on Embedded Networked Sensors (EmNetS-II)

Carlton Crest Hotel, 169-179 Thomas Street, Sydney, NSW 2000, Australia

The Second IEEE Workshop on Embedded Networked Sensors (EmNetS-II) 
will bring together researchers working in the broad area of embedded, 
networked sensors.  The goal of the workshop is to promote 
community-wide discussion of ideas that will influence and foster 
continued research in the field.  The workshop will provide a venue for 
researchers to present new ideas that have the potential to 
significantly impact the community in the long term, especially those 
exploring how practical considerations or novel application scenarios 
and requirements shape the design of these embedded and sensor 
networks.  This is a very focussed single-track workshop.  The workshop 
program consists of 17 full papers and 7 posters with many 
innovative ideas from leading research groups across the globe.
The highlight of this year's workshop will be a keynote address by
Dr Guru Parulkar, National Science Foundation (NSF) Program Director
(Computer and Network Systems Division).

Please check the conference and workshop URLs for timing information and 
further details on the program, accommodation and registration.

                   http://www.cse.unsw.edu.au/~emnet

Please note that early (discounted) registration ends April 30th, 2005.

On behalf of the IEEE Emnets-II team,

Geoff James, CSIRO Australia

I was not so clear on my last sentence.  I mean we don't have any
intention to use v4 HoA for v4 mobility on MIPv6 in our draft.  Not
talking about MIPv4's NAT traversal mechanism. 
Since MIP6 has different signaling way, we cannot simply re-use the
MIPv4 mechanism to MIPv6. However, there are serveral points which we
can re-use.

There are many options which tunnel we will use on MIPv6 for NAT or no
NAT network. However, we need to think about signaling between MN-HA
to deal with IPv4 network. In our draft, we provide many tunnel
methods support,but I don't have strong intention for this. I mean we
can discuss this later.

That's one possibility if it's worth to consider. Maybe yes in terms
of filitering/blocks.

let's discuss these once WG takes action:-)

Hello Pekka

I believe seamless connectivity is KEY to make mobility services
deploy. MN can keep communication by v6 HoA regardless of v4/nat/v6
network. It will be similar invention, but it makes sense to work on
this. This is because MIP6/NEMO are also protocols creating tunnel
between MN and HA. Simply extend MIP6/NEMO tunnel to support v4/NAT
traversal.

Not sure which working group would be fit for this proposal, so
I am posting it to multiple mailing list (MIP4,MIP6 and MIPSHOP)

======================================================
A New Internet-Draft is available from the on-line Internet-Drafts
directories.


	Title		: Link Characteristic Information for Mobile IP
	Author(s)	: S. Park, M. Lee
	Filename	: draft-daniel-mip-link-characteristic-00.txt
	Pages		: 8
	Date		: 2005-4-13
	
This document introduces a new model for link characteristic
information that is sent by the mobile node to let the correspondent
node know which link is being used for communication between them.
This utility allows the correspondent node to forward its ongoing
traffics within the bandwidth of the mobile node while the mobile
node changes its link.  This model can be applicable for Mobile IPv4
as well as Mobile IPv6.

thanks Francis.

here is the new text.

    The Home Agent should have named SPD entries per mobile node, based
    on the identity of the mobile node.  The identity of the mobile node
    is stored in the "Name" selector in the SPD [5].  The Home Address
    presented by the mobile node during the IKE negotiation is stored as
    the Remote IP address in the resultant IPsec security associations.
    The home agent MAY also have generic SPD entries to prevent mobility
    header traffic that requires IPsec protection from bypassing the
    IPsec filters.

is this okay with everyone?

so you want the default mode be the same as in RFC 3776, but present
the "tunnel everything" mode and the "MH type as a selector" as two
options?

I disagree with this. IMHO, the "MH type as a selector" should be
supported atleast by the Home Agent, so that some mobiles can take
advantage of this. the "tunnel everything mode" can be specified
as part of privacy solution documents.

okay, I added the following to sectino 5.2

    If public key
    based mechanism is available, it should be the preferred mechanism
    for mutual authentication.

Hi,

This is a draft we submitted recently to create a new Mobility Header 
message for a Home Agent to signal a Mobile Node that it should acquire 
a new home agent.  It's a combination of a number of different drafts 
with similar designs from various authors.  Comments are appreciated.

Thanks,

-Brian

my impression is that use misuse the term trust relationship to define
something else.=20
in fact it is not really a definition but rather an example. btw, i =
disliked
this definition already in the problem statement draft.=20

i use the following definition for trust relationship:=20

a trust relationship denotes a mutual a priori relationship
   between the involved organizations or parties where the parties
   believe that the other parties will behave correctly even in the
   future.

i got confused by the fact that you have everything pre-configured and =
then
you have a problem with authorization since you do not perform the
authorization based on the pre-established credentials and the =
configuration
parameters but on something else that demands interaction with the aaa
infrastructure.=20

wouldn't it be better to just say that the nai is used to associate a =
user.=20

(which is even not fully correct if you consider pre-paid cards but =
that's
problably a difficult issue to get the text truely right.)

hmm. this is not what i read from the requirement. you explanation =
seems to
say that the aaah should dictate the usage of bi-directional tunneling. =

i got the impression that you would like to install packet filters and =
to
perform a qos reservation. this would be interesting for our work with =
the
diameter qos application.=20

the aaa server is asked to perform authorization by relying on the
authentication provided to the home agent.=20

i will re-visit draft-giaretta-mip6-authorization-eap-02 with regard to =
this

and i

it might be sufficient to have this information implicit in the =

true, if it is important at all.

i remember the discussions about considering ikev1 as well but i wasn't =

for some of the scenarios i had the impression that it is not necessary =
to
use the same identity for bootstrapping and for subsequent mip6 usage.=20
in the bootstrapping you might want to use a nai (particularly in the
context of an eap protocol run). as a result of the bootstrapping you
create, for example, a shared secret for ikev2. subsequently, you use =
ikev2
to create the ipsec sa to protect mipv6 signaling. what identity do you =
use
to identify the pre-shared secret? do you use the nai again or =
something
else?=20

Dear MIP6 Group
 
A new WG I-D is announced in DNA WG. 
 
DNA with unmodified routers: Prefix list based approach
draft-ietf-dna-cpl-00.txt
 
The current MD (Movement Detection) scheme for MIPv6 is less than 
optimal. When a host moves to an another subnet, if it uses NUD, it 
would take roughly 3 secs to detect a change. Moreover, link-local scope 
of router addresses may cause the host to make a wrong decision.   
 
This draft describes a fast & robust DNA/MD scheme without a standard 
change, which can be adopted to existing MIPv6 code right now. 
 
Upon establishing a new link-layer connection, a host checks for link change, 
i.e. determines whether it still remains at the same link or not. 
 
Currently there is one thing which can represent the identify of a link,
 
   'The set of all the global and valid prefixes assigned to a link.'
 
We propose that, at each attached link, the host generates the Complete 
Prefix List, that is, the prefix list contains all the prefixes on the link, 
and when it receives a hint of a a possible link change, (usually link UP
notification from link-layer), it detects the identity of the currently attached
link by consulting the existing prefix list.  
 
We describe how to generate the Complete Prefix List and to robustly check 
for link change even in the presence of packet losses. 
 
A URL for this Internet-Draft is:
 
http://www.ietf.org/internet-drafts/draft-ietf-dna-cpl-00.txt
 
We are looking forward to your feedback, especially from the people who 
actually implement MIPv6 stack. 
 
Thanks in advance for your kind consideration. 
 
Best Regards

Hello all,

We posted an I-D that describes HA discovery with the help of DHCP6.
We would appreciate to hear your comments.
 
 -------------------------------------------------------------------- 
 Document title : DHCP Option for Home Agent Discovery in MIPv6
 Authors : HeeJin Jang, Alper Yegin, JinHyeock Choi
 Filename : draft-jang-dhc-haopt-01.txt
 Date : 2005-4-25
 Pages : 13
 
 Abstract : This draft defines a DHCP-based scheme to enable 
   dynamic discovery of Mobile IPv6 home agent address and home 
   subnet. New DHCP options are defined to carry the information 
   from a DHCP server to the DHCP client running on the mobile node.

Hello!

According to
http://www.microsoft.com/technet/community/columns/cableguy/cg0904.mspx#EBAA
there is correspondent node support in Windows XP SP1, XP SP2 and Server
2003 based on an obsolete version of the draft.

I need full support (MN, HA, CN). I sent an email request for an
application to mipv6-fb@microsoft.com  , but I haven`t got the
response.

Has anybody tried to get above application??

Or, is there any support (free) for MIPv6 (or MIPv4) in Windows
systems?

Please , help.

-- 
PS. Please, forgive me my English mistakes.
Regards
Pliniu
