Re: Problems getting 2 NICs to work.

They aren't in the same net. It's 2 separate ranges although they do travel over the same hardware. Each interface is configured to use it's own gateway (the 256 address of it's range) but that is the same physical eth interface on my router.

When I have two cables connected and the eth0 interface up and eth1 down, both lights are lit up. In fact, at any point that I have a cable in either interface and the other end is in a switch, they are lit up. But "ifconfig" of course only reports the active eth interface as being up. If I remove the eth0 cable, I lose networking.

As soon as this is activated, networking stops functioning. I can't ping in or out. Am I missing some key step? I know that it works becasue I'm running a firewall on another machine that's running a 2.4.20 kernel and it was autoconfigured and it's functioning properly.

One of the interfaces work and the other not?

Have you tried:
 a) configuring eth0 only and connect both cables
 b) ping some external IP: ping IP  (don't use -I)
 c) remove cable from 1st interface
 c) does the 2sn interface lit up?
 d) is the ping still working?

It could be a case of a dual ethernet card working as a failover, so if
1st interface works, then the second isn't needed.

This probably happens due to both interfaces being in the same logical
and physical net...
