Why would your ISP run a VPN server? I know that some ISPs, mainly in
Austria use PPTP for internet access, but there it's ok, for you don't
need the privacy you want are expecting from a VPN.

Windows 2000 and XP can handle IPsec, so you can connect with FreeS/WAN.
OpenVPN is also available for Windoze 2k/XK, but not for Win9x.

So the only situation PPTP really is needed (if it is needed at all) are
Win98 computers.

P.S.: 
FreeS/Wan RPMs are available at the http://freeswan.org, 
FreeS/WAN w. x509 patch is at http://www.freeswan.ca (they have tarballs
but a specfile is included),
For SuperFreeS/WAN there are source RPMs at
http://tis.foobar.fi/software/ 
OpenVPM for FC1 can be found in Dag Wieers repo.
