Direct Connection possible, but can't join via Browser.

Hey guys.

I recently re-started hosting my servers again for Halo. Before, all 4 of my servers were joinable via the in-game browser. Now, none of my servers are. When I join the server ingame, it says connecting to "IP:port", where the IP is the correct IP, but the port is different. Instead of my set post in my .bat (-port 8765) the game was trying to connect to port 55155. (I don't know why. I ran uTorrent's port checker, and it said the port was closed) The ports are correctly forwarded (I'm 100% sure of this). To further test it, I edited the-port switch to say -port 55155, and re-started the server. Tried joining again, but the port changed to 551xx (don't remember)... Is this some known issue?.. I'm not using any SAPP.dll's, or _extended exe's

All my friends can join via direct IP, with the correct port (if the -port switch is 8765, then they can join using port 8765)

Thanks.
