Trying to get 2 network cards to work, only getting one.
 

Got a problem on a SuSe 8.2 box. I'm trying to set it up as a firewall, using Yast's built in firewall feature. So this spare computer should be a hardware firewall. If I understand this correctly, you set up a computer with two ethernet cards. Run a wire from the wall to eth0, then run another from eth1 to your internal network.

I've got one Ethernet card working on this computer, but only one. If I enter ifconfig, I get a readout for the loopback and for eth0. During bootup, the computer initializes eth0 but not eth1. It won't detect the card, and acts as though it doesn't exist.

I entertained the idea that the card was broken, but I tried this same thing inside another machine. SuSe autodetected the card just fine. I even switched the one working card to a different slot on the motherboard. Since it still worked, I know that the slot is fine.

How can I get this thing to work with two network cards? How can I get eth1 to work?

run modprobe with the corresponding module of you card model.

For example, If my eth1 is a Realtek 8139, I would do "modprobe rt8139" and eth1 would show up.

I got it partially working. See, eth0 and eth1 will show up now. That's good. On the other hand, eth1 won't ping out to our main server. I can get eth0 and eth1 to ping each other. Any idea why?
