I don't know. I've always used TCP/IP. Are your game versions the same? If one of you has a more recent patch downloaded then I know you won't be able to play, but other than that I'm not sure. Sorry :-(

Make sure you arnt using a router, just use a normal RJ45 LAN jack, otherwise the router will skew things up for you!
Easiest way to get the game setup is to install Hamachi (google it!), Set up a private network(www.portforward.com). Both join the same private network and then run the game connecting via TCP/IP with the IP address Hamachi gives you!
