Odd IP & eth problem

Hello,

I have a very odd problem here. I have recently found out that I have a server setup wrong. Basically, it has two ethernet cards eth0 and eth1. They are both setup using the same ip address (which is what caused the problems). Now, eth1 is the only one that is connected to the network. Everything works fine except machines cannot talk to each other on the local network. All machines work fine connecting to machines outside of the network. So... the server can connect and serve web pages, etc. But cannot send an email (or even ping) from machine1-> machine2.

Now, since it is the only one connected to the network, eth1 should be setup with all of the IP addresses. It appears that all IP's were setup on eth0. Here is the output of route -n:

Destination Gateway Genmask Flags Metric Ref Use Iface

216.xx.xxx.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

0.0.0.0 216.xx.xxx.1 0.0.0.0 UG 0 0 0 eth1
0.0.0.0 216.xx.xxx.1 0.0.0.0 UG 0 0 0 eth0

(There are more IP's than that listed, I only copied part of them)

SO... I want to change these IP's over to eth1 so that I can shut down the eth0 interface. Does anyone know how to do that?

(If I shut down the eth0 interface, all of the IP's still work, but for some reason DNS does not, which is no good).

Thanks!
