Hello,
Like many people my friend can not join my game.
My NAT is in TDB.
I made a DMZ to my machine on my router and I totally disabled the firewall (basic windows).
As much to tell you that the security of my network is assured ^^.
More seriously everything worked perfectly before the last update (Train & Uranium).
The game has no interest for me if I can not play with my friends (bought for that).
Thank you.
