Cual es el puerto por defecto que usa el juego al crear una partida online??
Network ports
Some information for firewall configurations to play nice with quake4:
all game traffic is UDP
by default servers listen on port 28004 ( if you run several servers on the same machines, it will use 28004, 28005 etc. )
your server needs to be able to talk to the master server at q4master.idsoftware.com on port 27950
Parece ke usa del 28004 en adelante
