Smile need help installing 2 network cards with RH7.3

I have installed Apache on RH7.3 and it works well with one ethernet card. When I add eth1 I have problems. I can ping eth0, eth1 and lo internally but I cannot ping out to the network. I can also not ping RH7.3 from the network. I am new to linux. I want to put RH7.3 between my DSL modem and my ethernet switch.
Please help.

your setup is wrong. you cannot have two ips of the same subnet for two differen ethernet cards. (you can, but this is a very special case that you 99.9% won´t need - its for redundant network connections and needs quite some more setup)

right setup would be eg.:

NIC1 (to your DSL router which has address 192.168.2.100)
192.168.2.1
255.255.255.0

NIC2 (to your internal network whose machines have 192.168.1.*)
192.168.1.1
255.255.255.0

default gw.: 192.168.2.100 (your DSL router)
