Hi, I have played SOASE (Entrenchment) a few times with a friend against unfair AI via Lan and now wanted to play online. When I log in to ICO, I can't see any games or players I just see an empty box. I read about port fowarding a few times but I don't quite know ho to configure my router is there another possibility, or is the problem something else entirely?
