EDIT: Router, ports are opened, still have connection tmieout problems.

Technical forum, and, I don't know, sorry.

EDIT: Yes, I have a router, and yes, my ports are open.

*BUMP*
Ports 10052 to 10054 are opened on both TCP and UDP.

What kind of router do you have?

The config prog says Vigor 2900. For the record, I have ports 10052 to 10054 opened on both TCP and UDP.

You could always try temporarily using DMZ and see if you can join a game without timing out. You might want to consider using a second firewall if you do this.

You can also try joining servers through GIP or JazzForce. This seems to work for some people.
