So, I'm not really good at searching, but I tried to look for an answer at the forum and find nothing... It may be dumb, but I'm trying to play 0 A.D with my brother in multiplayer and I'm not being sucessful. Our connection to internet is through a router, what means that we both have the same IP adress. So when I type the IP adress to join his game, nothing happens (and vice versa)! Can someone explains what's happening? I don't think I got any firewall, since I did not installed any... I'm using Ubuntu 11.04 (and so does he). What should I do to play with him? Thanks in advance.
