AFAIK, and I certainly could be wrong about this, but XP can't act as an IPSec server...Others can
speak to that issue.
You can, however, setup a PPTP VPN tunnel...

In the case of PPTP VPN you need to forward TCP Port 1723 and enable GRE Protocol 47 traffic through
any firewall/NAT/router at the server end to the private LAN IP of the PPTP VPN server. The later is
sometimes called "PPTP Pass Through" or "VPN Pass Through" on consumer grade routers...
Another alternative may be a SSH tunnel. I do that into my home LAN and use either Remote
Desktop/UltraVNC to access my XP Pro/Home desktops or WinSCP to transfer files to/from the home LAN
from a remote location... The SSH tunnel is encrypted end-to-end and is very easy to setup and use,
particularly for a home user.

In the case of SSH you need to forward TCP Port 22 through the firewall/NAT/router to the SSH
server's private LAN IP address.
