Most of the time, a game's home web site will document what ports to forward or even reveal you have to put a server in the DMZ.
But there is a severe risk that such a machine will be compromised so be ready to format and reinstall it all if that happens.
There are articles about the security issues in such game servers, so I ask you do this with the knowledge the machine's hard disk contents are fair game.
