Raion,

I think that the thing you need to look at is blocking any incoming traffic on the printer and file sharing ports (can't remember them of the top of my head).

The risk of file and printer sharing is that you open a listener on additional ports, which intruders can try to hijack. If you block these at your router, you start limiting the risk.

The second thing to do is to beef up your firewall on the PC which is going to be doing the sharing. Only allow incoming connections from the address (ideally MAC address) of the other PC. You could also look at what limits you can configure in your router to do MAC address filtering.

Basically, the more you can limit who is allowed to do what the less chances you take.

Cheers,
