Correct. The Windows XP built in firewall should be sufficient.
Some of the third party products are better for computer literate users, but
the majority are confused by messages like 'Application xxx is trying to
connect to host www.domain.com on port 384. Do you want to allow this' and
just click Yes anyway, so the additional safety is negated.

What VPN client are you using? Maybe try using a third party firewall on your
own machine so it can tell you what ports are being used by the VPN client
and open those specific ports on the built in XP firewall for your general
users.
