RAS (Dial in) Interface -- No Internet Access

We want to create a Windows 8.1 Pro  PC to  as a VPN Server. I had Configured it and forward a port 1723 PPTP from router Also.

LAN IP is : 192.168.92.100, 255.255.255.0, Gateway is 192.168.92.1 and DNS is set 192.168.92.1 and Public Static I

VPN LAN is specific that is : 192.168.100.1 to 192.168.100.10.

After Configuring both side and client is able to connect the VPN connection he lost the internet connection and get the message No Internet Access.

Also i check it from server side: screenshot is 

From windows firewall port 1723 is enable, forwarded via router also.
