I know this isn't a networking security topic, but it is a networking question.

I am trying to set two computers together with a cross-over patch cable to play a direct game between two computers.

The problem I get is this:

Cross-Over Patch cable (is it also known as a null modem cable?)

I have tried to set the game through 3 different types of networking; Lan (IPX), Lan (UDP), and DCC (Null Modem)

When I have the CO Cable linked, I can get both 'puters working as a network, yet Starcraft and other games won't tranfer each other a packet to play the game. Am I doing something wrong?
