I installed hamachi, granted certain privilages, so firewall couldn't block it, made a new network, my friend connected, We could chat, I made a OPF socket Lan game, he typed my hamachi IP in the remote screen...and didn't see the game. Something is really wrong, are there any other possible solutions ? It is kind of strange, can the problem be caused by the same internet provider ? I know that probably not, but I'm trying every solution that comes to my mind, so I can finally play one of my favourite games.
