On your router, did you open TCP port 1723? You're also supposed open protocol 47 (GRE), but not all routers will allow you to do this. In many casses, as long as you open 1723, you should be working fine.

Can you pls find this attachment file.

How do you have your VPN server configured right now? More often than not, once I opened that port, it was usually something on the server I needed to tweak to get things working.

PS- Looking at the manual there is an "ALG" tab below virtual server where you can enable PPTP pass-through.  This is usually for outgoing connections but I would enable if not already done.
