Are you running a dedicated server or are you playing the game on the same computer?
If you are playing the game on the same computer you have to place the computer in the "DMZ".
To check GAMESPY you have to leave the game, and when you connect to GAMESPY your game isn't running.
If you run a dedicated server (1 computer that keeps track of all game data and syncs the clients) and play on another you would have another IP address like 192.168.0.3. you at 192.168.0.2 would join the LAN game at 192.168.0.3. 192.168.0.3 is in the "DMZ" or the same as 12.214.202.218 and would broadcast it's game info on the net to GAMESPY, TASE, Clanbase, kali, etc. Players would find your game at one of these services or with the ingame browser. If you are playing on the same computer that you host the game on start your game, run around for twenty min. Someone should find you.
