Server 2008 behind NAT, needing VPN with Vista AND XP Pro


I need to know how to establish a VPN from my Windows Server 2008.

It is behind a NAT, plus I need to be able to connect with XP Pro SP3, plus Vista SP1.

heard XP will not do SSTP.

Should I do OPENVPN? or what?

Would LOVE recommendations.  And a place with instructions.

PPTP, L2TP as well as openVPN could be an option.  No matter which option you choose, you would need to configure port forwarding on your router to allow PPTP, L2TP or openVPN port from the public IP to get to the IP of the windows 2008 server.,289483,sid100_gci1252324,00.html

You can setup multiple VPN options available at the same time, these are not mutually exclusive.
