Browsing network shares from behind a router.

I'm in a dorm. In my room I have a desktop and an ancient laptop. Since the Resnet only assigns us one IP, I use a router to connect both PC and laptop to the internet. Swapping off the router is not simple because of a buggy as shit activation process the ResNet service uses to bind to a MAC.

Is there a way to browse network shares even though I'm on my private subnet? I'm not in the mood to violate my universities AUP, so no uber-fast IP range share scanner type progs.

in the time you've taken to write all these things you could have been making money at work (like I am right now) and/or driving to the store to buy the wireless NIC you need to cure your terminal retardation
