Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
try this Q: What ports need to be open on a firewall or router to run the game? A: 1716 for the game and PunkBuster (UDP), 1717 for the gamequery (UDP), 1718 for master server query (UDP), 8777 for standard UT query (UDP), 27900 for GameSpy (UDP), 20045 for Auth server (TCP).
If you are running your own game server on your home PC, then in addition to the ports above you need to make sure the following are open: 24300 through 24350 for PB (UDP). (Last Updated: 2005-08-27)
