I solved the 3 NIC card problem in my Fedora Core2 machine. I didn't have time to really dig into any kernel settings as such so I ended up putting in a fourth NIC card. Now I have three NIC cards that work and route the way I want them to. NIC card ETH1 is there and active but will not work until I it is installed by itself or is in a 2 NIC card system. I have no idea why ETH1 quits working when there are 3 NIC cards, but when I add the fourth NIC card and give it the address that I had on ETH1 and the same routes, it works perfect with the other two. Oh well, I guess it is a cheap solution with NIC cards only costing $10 :)
