i know about xlink and xbc and all those alike but i want to know if theres a program or a way to tunnel both or a way to tunnel which port u want to with a specific program? i in a dorm and want to connect more dorm LANs to our basically.

I don't believe there's a program out there that'll do quite what you want, your college dorms are probably physically connected to different switches and routers then go to the master router, so I'm thinking XBC or Xlink would be your best bet (I'm in the same boat you're in)
