The game uses the following ports to communicate:
- TCP : 80, 443, 6667, 6668, 16667, 15000-15500
- UDP : 16000-17000
The UDP ports are particularly important for the action game.
If you are having problems joining games, or get an error message that says “unable to ping game servers”, then you probably need to open these ports in your firewall.
