Title: Is is possible to change client net port ?
Post by: yossarianuk on March 18, 2008, 04:25:46 PM: Hi.

Is there a way to change the UDP port used by paintball2 ?

Cheers

or....

You could use PAT = port address translation - on your firewall. Where you have your wirewall change the outbound and inbound port.

I believe you can override this by specifying the client port in the command line, but I would recommend against using the "default" value of 27901 since it would be trivial for someone to fire up Q2MSG and start stuffing commands down to the client.

+set qport #####

You can't change it in-game because it's write protected.
