RE: Where NAT disenfranchises the end-user ...
I'm not sure who was first, in terms of IOS NAT and ip_masq. If memory serves (and it usually doesn't) then 11.2 was released around Aug 97. I don't see any easy way to identify the release date. However, I think the linux code is older, although of course its largely based upon the BSD firewall code. The online source log shows 38 * Masquerading functionality 39 * 40 * Copyright (c) 1994 Pauline Middelink 41 * 42 * The pieces which added masquerading functionality are totally 43 * my responsibility and have nothing to with the original authors 44 * copyright or doing. 45 * 46 * Parts distributed under GPL. 47 * 48 * Fixes: 49 * Pauline Middelink : Added masquerading. 50 * Alan Cox : Fixed an error in the merge. 51 * Thomas Quinot : Fixed port spoofing. 52 * Alan Cox : Cleaned up retransmits in spoofing. 53 * Alan Cox : Cleaned up length setting. 54 * Wouter Gadeyne : Fixed masquerading support of ftp PORT commands 55 * 56 * Juan Jose Ciarlante : Masquerading code moved to ip_masq.c But Cisco was promoting NAT much earlier. They bought the old NTI hardware (now called the PIX), and its primary purpose in life was NAT -- the company was called Network Translations Inc. Looks like my first PIX install was 3 July 1996, so that predates IOS installations, I think. --woody On Sunday, September 09, 2001 6:22 AM, Circusnuts wrote: > > Yep- NAT showed up in Cisco IOS in the 11.2 version.
