Error - View Single Post - xp vpn server behind BEFSR81 router with NAT

I see you've opened up port 1723 TCP which is used for PPTP connections and port 500 UDP which is for IPSec connections, please verify which one you really need to have opened up. (and also, please mention which location you're using as a server)
Apart from this, I'm guessing that both Windows XP computers are in the 192.168.1.x subnet which will cause your VPN not to work, please move one of them out of that range by changing the local subnet on one end.
