I am a college student on a small campus. The school's network is set up like so: one single router with a bunch of different subnets connected to it. A friend and I would like to play Minecraft, and he's on a different subnet than I.
I've seen this set of instructions.
However, since he and I are connected via the same router, is it possible to play minecraft without going to the internet and, therefore, don't have to make a server and go through all that mess? (I'm not sure if the minecraft software even allows this atm?)
Earlier this year we tried to connect via wireless, and I could see his game but I could not connect to it. I have yet to try using a hardline to see if that fixes the problem.
