Since update 1.22, I am unable to host multiplayer matches peer to peer. I will host a game but will not show on the server browser of ARMA. When we trying to use the steam functions such as join game, view game info or joining the server through steam game browser. An error would appear. Different people tried hosting a game but none of us could join one another. We tried using Port Forwarding but had no success. Normal dedicated servers run fine but P2P seems to be completely broken.

Thanks for all the effort you guys have put into the game and your continued dedication to refining and shaping the game.
Cheers

PS. In the previous patch (1.18), when we hosted games we would have to select gamespy servers to see our coop games. Now with that functionality removed and only "Internet" option remaining, we cant join any P2P games. Maybe the problem has been in the making for some time?
