If you have tried many thing other people suggest like rebooting, reloading hardware and re-installing the VPN or dial in connection, you still get the same problem. I will suggest to check the router settings and make sure TCP Port 1723, IP Protocol 47 (GRE) are opened.
Enabled pptp vpn server 2. Opened port 1723 in my router (used the UPnP Port Forwarding) and forwarded to internal ip of nas (192.168.1.x). 3. Created a vpn connection from windows 7. It connects, but that is about all I can do, tried to run the QNAP finder and i didn't find the NAS.
