Cisco Pass-thru VPN question

[Rapidskies]

I have a customer looking to pass thru a vpn connection from a home user to a pc at the main site behind a Cisco 1720 Router w/ IOS ver 12.2. The router is NATing and I believe I need to forward traffic on ports 1723 & 47 (GRE) to the inside ip 192.168.1.225, but it isn't working. The outside pc never tries to establish a connection using WindowsXP (get an error of no answer), though I do see some traffic accross access-list 101 for port 1723. Any ideas? Here is the current config:

!

service timestamps debug uptime
service timestamps log uptime
