Ah, I suspected as much.

Having been an admin for a large clan and hosted many games in the past I know
the pain you feel. The first thing to know is that as a game server you face
an additional risk as it will attract more hack attempts. Then it's just a
matter of how good they are.

Next I should point out that many games end up having a linux server version
so that makes things easier.

What I did is use an old computer as my firewall. This way I have full control
of what it does. (Again I use OpenBSD so there are a number of advantages
over iptables.) But I added port definitions for each type of game and could
just add or remove # to open up ports for that game.

The problem you face is no doubt not knowing which ports a particular game
uses. Once again OpenBSD does a fine job with that by telling me which ports
are being accessed. Then I simply add them to my configuration.

You can do it with iptables as well so all you need to do is learn what
commands to execute to identify them. But you'd still require a computer to
act as the firewall. The small routers you buy these days are crippled in
many ways but have a nice web gui. If you just venture past that you'd be
sitting pretty.
