Title: Disable PAT on certain port (Quake III Server) Post by: Mondo1287 on Saturday 14 November 2009, 08:24:38 am Is there a way that I can keep a source port from being modified once it's been NAT'd? Say I connect to an outside server using local source port 2000, I need that source port to remain 2000 as it leaves the firewall, instead of being changed to something else.
It's only an issue with Quake servers, since the master server lists the port your game is using as the source port it sees coming from your server. So if your server is on port 2000 and it sends an update packet to the master server, when the firewall changes the source port due to NAT/PAT to some random port, say 30000, the Quake master server thinks your server is running on port 30000. All the clients trying to connect to your server will try to use port 30000. |
