I have eth1 and eth2 NIC in my Ubuntu. Everything works fine. I have two static IP, on XP and Ubuntu. XP - 192.168.0.1, Ubuntu is 192.168.0.2 on eth1, eth2 is set on DHCP. I have Lan on and internet sharing. I share internet over XP. Can somebody explain to me some things: I assume that eth1 is my network card? What is eth0 then? What address should I have on eth0? Is DHCP right option on eth0? I'm little confused.
