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.

You cannot do this because getting access to windows' special brand of shared folders requires that you be on the same private network as the targets. If you set your router to operate in switch mode, you would be able to access those folders but you'd be showing your network two different MAC addresses.

Now, strictly speaking, your ROUTER could see the shared folders, because your touter is on the same network as the shared folders. So if your PC has two NICs you could scrap the router, set up routed connection sharing, and be able to access those shared folders with just the PC (sharing the connection with the laptop in a firewalled, routed mode would disable the laptop from being able to see them, however).

This is stupid, it's easier just to unplug the router and plug the PC in direct when you need to steal copyrighted materials off your l33t dormfriends.
