So a friend and I want to play multiplayer on Sins Diplomacy. We are trying to do lan multiplayer, but when either of us try and create a game, we can't see the created game in the "join game" menu. We've tried putting in each other's ip address, but that doesn't seem to work. We've also put Ethernet cables between our computers, but that doesn't help. Does it matter that we are playing on a very large LAN network? We also have the same version and no mods, so that is not a problem.
