[BEHAVE] FW: Layer2-Aware NAT (draft-miles-behave-l2nat-00)

["MILES DAVID" <[e-mail]>]

All,

A new method for NAT44 has been posted based on some of the work in the
Montreal v4/v6 coexistence meeting and methods described in Dual Stack
Lite.
L2-Aware NAT proposes a virtual NAT mapping table for each layer2
connection (be that VLAN, ATM, PPP or L2TP [similar to Dual Stack
Lite]).

We would see this work merging into a larger CGN document. The draft
will be presented in the BEHAVE session at IETF74.

Comments are most welcome!

Best Regards,

-David

Abstract:
This document describes a "Layer2-Aware" IPv4-to-IPv4 (NAT44) Service
Provider NAT function that identifies subscriber traffic based on IP-
independent methods such as a link-layer address, VLAN, PPP session,
tunnel, etc. in order to allow one to either avoid "double-NAT"
(NAT444) of subscriber IP traffic altogether, the need for additional
"Shared Service-Provider" IPv4 address space, or partitioning of RFC
1918 space between subscribers.  While the mechanisms described in this
document may be applicable to a variety of network architectures, the
primary focus is on residential "fixed-line"
Internet access.
