I have a centos 4.0 box that has three network interfaces and is used as 
router. It runs shorewall as a two-ISP firewall for a single LAN.
This morning, the motherboard's LAN interface gave trouble, spewing out 
IRQ problems, so I disabled it and changed the network cards. As I only 
had two slots, I tried a dual NIC card, but it crashed the system every 
Right now I am trying to fit two single NOCs in and to bring the machine 
back up. However, I can;t get any traffic to route. The DHCP ADSL card 
will not get an IP. I have used Kudzu to configure the new cards, turned 
off Shorewall, but no matter what I do, teh cards can't talk to the WAN 
or LAN. The ADSL is fine, my laptop gets and IP easily.
Any ideas what I need to look for?
