I've hosted games of various sorts from a machine behind a NAT, both 
when that NAT is Linux and when that NAT is Linux-hidden-in-a-router. 
You need to forward traffic connecting to the NAT device through to the 
machine running the service.  Same principle as running a web, ssh or 
any other kind of service behind a NAT device.

The quickest way to do it on a linux host is to run redir(1).  This only 
works for TCP though, so you'll have to mess around with iptables in 
some manner I'm not entirely sure of to get it to work for UDP.
