I set up a home network recently. I hosted a game on one computer and logged into the game on that computer. Had a roommate try to connect to the server on his computer and he got a failed message. I tried on another laptop of mine and got the same issue. Players from outside the network can join normally. This does not affect any games hosted by others outside the network.
I can only note to use the forum search here, since the same trouble has been encountered by various other people and is not exactly a BYOND related issue it seems. I'm sorry, but I can not provide you with a specific solution for the problem.
