It depends on the game you are trying to play and how it works. For some games, it doesn't really matter, you can just, say, tunnel UDP broadcast, and the game will route itself over the internet just fine. WC3 is a good example. You can play behind NAT or on a public unfirewalled IP, either way, just by tunneling the broadcast packets, the game will be able to find the game-server and play just fine.
For other games, like AoM, you must create a LAN and be on the same subnet and have no IP conflicts, and you have to tunnel ARP and all of the UDP packtets, broadcast or not. Even though AoM has a direct IP connect feature, it only works if all players, not just the server, but every single player, has a public IP that is not NATed. If just 1 person is NATed, you must ALL NAT yourself and be on the same virtual LAN and use GIT, and it will work.
I have tested both AoM and WC3 because I own them and so do some of my friends, but I likely do not have whatever particular game you are trying to use.
