The rulesets included in the FreeBSD Handbook and IPFW documentation,
namely rc.firewall, are quite primitive. You may want to consider using
something a bit more advanced.

Discovering ports is a trivial matter of running tcpdump and attempting
a connection with the game. You will most likely find that dynamic rules
will allow this ingress traffic, without the need to explicitly allow it.

If you post the output of ipfw list, I can assist in the creation of a
more scalable ruleset.
