You won't believe that I have NEVER done this.
Play on-line 2 player co-op.
I have a wireless hub at my place, I have 2 laptops with ArmA Gold patched to 1.14 on both.
I want to set up a game for only me and my girlfriend to play co-op missions on our own laptops in the same location.
Any tips would be very welcome.
I apologize for my stupidity but ArmA is the first game I have wanted to play online co-op.
