First of all if you have Windows Xp you and two nic's in the main computer then you wont need a crossover cable. Use the network wizard to set up the first computer to the internet then, set up a small office network through the other nic. That should be all you need to do.
Can someone help me to setup a crossover cable network? I know I can just buy a hub or a switch, but I dont need it. I just want to connect my dad's pc to my pc. Right now, my pc is the one thats connecting to the internet throu a cable modem, using the ethernet port on my asus p4p800 dlx mobo. I want to set my pc up as the gateway, so I installed another nic to it. I got the crossover cable too. Both pcs r running WinXP Pro. Now, I want to know how to setup the second nic on my pc. I tried ICS, and cant get it to work. I used 192.168.0.1 as the ip for the second nic, and 255.255.255.0 as the subnet mask. Then on my dad's pc, I used 192.168.0.2 as its ip and 255.255.255.0 as the subnet mask. Nothing in gateway and dns server. The first connection on my pc is shared.
Anything else that I'm missing?
