Two NIC's, Seperate Networks, Red Hat Enterprise 4

By peter.blais ·
Hi Folks,

I'm in a bit of a quandry with Red Hat Enterprise 4. Here's the scenario:

I have two NIC's installed. Each NIC works on a seperate network. For the purposes of this discussion, I have ETH0 on and ETH1 on

Here's my dilemma:

Both NIC's are configured to correctly talk on either network exclusively. However, if the default route is working with the 172.16 network, I can only SSH into that interface, and vice-versa; if the default route is working with the 192.168 network, I can only SSH into ETH1. When one is SSH"able", the other is not.

I've tried using the GUI configuration in KDE, I've tried ifup and ifdown (which successfully toggles which interface becomes the available one), I've tried manually editing the routing table -- all with no success.

Anyone else have this issue? Care to suggest a solution?
