Does it help if you put two addresses onto eth0 from different subnets (eg 192.168.0.1 and 172.16.0.1) so that icmp redirect is no longer appropriate (because this is used only between machines on a single subnet) ? Then your other machines which are talking to it can pretend that one address is eth0 and the other address is eth1. Antony.
