I'd like my friend to connect to my PC through a VPN connection.

My PC's IP is and my pc is connected to a Actiontec GT701 Router.
I have forwarded the following ports :

1723 tcp
500 tcp
50-51 tcp and udp

My friend connects, then it asks to username and password, then it disconnects (yes he's using the right login name / password).
When i try to connect to my VPN over my local LAN it works fine.

Anyone know what to do ?

What error does he get when connecting ? Possibly 721 ?
-It may be a problem with GRE. GRE is not configured with port forwarding as it is protocol 47 not port 47. This is probably enabled with an option such as "PPTP pass-through" on the Actiontech
-The subnets at either site should be different. You are using 192.168.0.x, so the other site needs to use something like 192.168.1.x
-Is the modem a combined router and modem and then you have the second router ? If so the combined modem/router needs to be in bridge mode
-Try disabling the Windows firewall and any other software firewalls such as Zone Alarm or McAfee security suite, on the computer to which you are trying to connect. Also if running Symantec's virus software try disabling "Internet Worm Protection" feature.
-Have a look at the following sites to see if you may have over looked anything in the configuration:
XP VPN server
XP VPN client:
