Connecting to a local XMage server

I cannot figure out how to do this. I want to play XMage against someone else that is on my local network, but when I try to connect to the server with the other computer, it fails to connect to the server. Does anyone know if this is even possible?
Changing the server IP address in the cfg file to match my local IP address (192.168.x.x) didn't help any. Connecting to the server from the same computer that is hosting it works fine using that same address.
Scouring the forums for a solution has yielded nothing for me. Perhaps it has been posted somewhere, but I can't find it.
Any help would be greatly appreciated.
