You do realize that if you can't host games its because your are behind a strict NAT right ? And the devs can't do anything about it because its P2P connection. So, if you can't host games using the fixed port option, is because you are not port fowarding properly.
BUT, if you CAN join some games, the problem isn't with you. You can't joint some lobbies because those hosts are behind strict NAT.
