I have a Linksys router/switch connected to a cable internet connection.
I have three XP Home edition computers connected to three of four ports
of the router. All three computers are sharing files as well as the
internet connection. Everything works fine.

The fourth port of the router I would like to use it to connect another
computer using XP Home edition. The difference here would be I don't
this fourth computer to have access to my other three computers in
anyway. I don't know the terms for this process or the set-up but I will
say I want to let this fourth computer only have access to the internet
and nothing else to do with the other three. First is isolating the
fourth computer from my other three computer possible with my Linksys
router (model BEFW11S4)? If so is it called tunneling or strapping this
fourth computer? I am ok at finding information on the internet if I
know some key words. I don't know the MAC address for the fourth
computer's NIC but I can get it. If this process is simple please
explain it to me.

Thank you.
