Sorry about the CC, when I hit "Reply", you were there first and I failed to delete you.

Of course it worked. I stuck the following 3 lines in front of the "ifup -a" in "/etc/init.d/networking": /sbin/nameif -s eth2 00:50:da:08:f0:4a # 3COM: set to eth2 /sbin/nameif -s eth1 00:40:05:45:19:22 # Linksys: set to eth1 /sbin/nameif -s eth0 00:50:da:08:f0:4a # 3COM: set to eth0 To the list readers/responders who suggested using the module interface, thankyou. I'm sure that such a procedure wold also work.
