RFC 2962 Title: An SNMP Application Level Gateway for Payload Address Translation Author(s): D. Raz, J. Schoenwaelder, B. Sugla Status: Informational Date: October 2000 Mailbox: raz@lucent.com, schoenw@ibr.cs.tu-bs.de, sugla@ispsoft.com Pages: 20 Characters: 46803 Updates/Obsoletes/SeeAlso: none I-D Tag: draft-ietf-nat-snmp-alg-05.txt URL: ftp://ftp.isi.edu/in-notes/rfc2962.txt This document describes the ALG (Application Level Gateway) for the SNMP (Simple Network Management Protocol) by which IP (Internet Protocol) addresses in the payload of SNMP packets are statically mapped from one group to another. The SNMP ALG is a specific case of an Application Level Gateway as described in RFC 2663. An SNMP ALG allows network management stations to manage multiple networks that use conflicting IP addresses. This can be important in environments where there is a need to use SNMP with NAT (Network Address Translator) in order to manage several potentially overlapping addressing realms. This document includes a detailed description of the requirements and limitations for an implementation of an SNMP Application Level Gateway. It also discusses other approaches to exchange SNMP packets across conflicting addressing realms. This document is a product of the Network Address Translators Working Group of the IETF.

Perhaps you could be interested in a paper by Van Jacobson about NAT, dated January 1992! You can find it at http://kbe.freeyellow.com/nat_van_jacobson.ps Cheers, Kjeld. -----Original Message----- From: Darren Reed [mailto:darrenr@reed.wattle.id.au] Sent: 21. september 2000 20:58 To: paul@francis.com Cc: nat@livingston.com Subject: Re: (NAT) headaches with NAT and patents.

The IBM patent is December 1994 - the URL for this group is http://www.ietf.org/ietf/IPR/NAT-VRRP-IBM The Cisco patent was filed November 1995 - number 5793763. > I gave the first public talk of NAT at the Vancouver IETF (summer 1990), and > published it in sigcomm CCR around '91-'92.
