connection problems

[keyser]

I can't barelly play 3v3 or 4v4. Because there will always be a guy that I have connection problems with. And each time it happen, I receive a message "connexion to host have timed out" => "keep trying" or "give up"

then when I give up, I receive another message about a proxy server

I decided to do as you said (Connection issues and solutions). And I think I've open the 6112 port (not quite sure), it works better, but still I can't connect to a lot of player...

I can host game and play ladder and some custom game. So I don't really understand.

there is the log :

Do a google search for your particular router on how to port forward or set your computer to DMZ. Make sure your local IP address isn't changing.
