Hello, Am writing to the list in the hope that someone out there might be able to shed some light on a weird problem I have with a multiple route configuration. Some time ago I configured a web server to have two different IP addresses from two different ranges on each of it''s two ethernet cards. I followed the excellent instructions at http://lartc.org/lartc.html#AEN268 and came up with the following configuration: #!/bin/bash /sbin/ip route add 194.164.97.0 dev eth0 src 194.164.97.252 table T1 /sbin/ip route add default via 194.164.97.1 table T1 /sbin/ip route add 86.54.82.144 dev eth1 src 86.54.82.146 table T2 /sbin/ip route add default via 86.54.82.145 table T2 /sbin/ip route add 194.164.97.0 dev eth0 src 194.164.97.252 /sbin/ip route add 86.54.82.144 dev eth1 src 86.54.82.146 /sbin/ip route add default via 194.164.97.1 /sbin/ip rule add from 194.164.97.252 table T1 /sbin/ip rule add from 86.54.82.146 table T2 /sbin/iptables-save I''m uncertain if the last line is actually needed there. Anyway, this worked perfectly, or seemed to. The two web sites could be accessed properly and I could use ping to access the internet via either interface, so ''ping -I eth0 lartc.org'' and ''ping -I eth1 lartc.org'' both worked absolutely fine. Now what''s gone wrong. My lovely web server''s RAID controller started failing and I have to move to another server in somewhat of a hurry. I copied over the configuration but on the new server it just doesn''t work. What happens is that whichever interface is defined in the ''/sbin/ip route add default via 194.164.97.1'' line of the configuration above becomes the only route out that works. So for example ''ping -I eth1 lartc.org'' no longer returns a result. Would appreciate any help, especially if someone can confirm that my configuration is correct and perhaps shed some light on other things that I may have overlooked, such as the correct kernel modules etc. For reference the install is Debian Etch, kernel 2.6.18-5-amd64. Any help much appreciated, Thanks in advance, Mike. -- ---------- Mike Harris Psand.net Tlf: +44 7811 671 893 / +34 69 676 3122 / +44 870 162 4927 ext 2 Fax: +44 870 162 4925 Web: http://psand.net PGP: http://www.psand.net/mike/mike.gpg.pub IRC: irc://irc.psand.net:6667/#psand ---------- Psand Limited is registered in England and Wales company number 03291616.
