How to set up a VPN on Karmic to XP

[Rafiq Hajat]

Hi everyone,
my offices have a wireless network set up for internet access through a
router. I wonder whether it would be possible to use this as a conduit
for a network linking various PC's (some running XP and other running
Ubuntu)to each other for file sharing and printing.
I have never set up a VPN or anything like it before, so simplicity and
your patience would be dearly appreciated.
