I saw the example from 'Can't use two links on a linux box - correction/addition' but there were a couple of differences in his setup tha concerned me, first was he was only running NAT on 1 of his 2 connections. My second and more important concern with using NAT and Linux is how do you make sure that if X computer starts a UDP connection with the outside world that all traffic on that connection comes from the same outside IP address (be it the dsl line or the T1 line)? -----Original Message----- From: Arthur van Leeuwen [mailto:arthurvl@xxxxxxxxxx] Sent: Tuesday, January 16, 2001 3:39 AM To: Daniel Jay Cc: 'lartc@xxxxxxxxxxxxxxx' Subject: Re: [LARTC] Advanced routing question.

Linux using Advanced Routing can be used to solve these problems, but for problem 2: at the IP level there is no way to figure out wether or not a link is down. Ofcourse, you can approximate problem 2, but you have no guarantees that the problem lies with the link and not with the servers you test your connectivity against, or the infrastructure to those servers beyond your direct link. There have been some postings on the mailing list on exactly the kind of setup you want.
