Internet access through VPN server 2008 r2

Hi,

I have set up a VPN server using one NIC. Works fine and VPN clients can connect ping etc.

However I would like the VPN clients to be able to access the internet on the VPN server side. I am puzzled as the VPN server can access and browse the internet, but not clients. I have set the clients up to direct all traffic through the tunnel.

For further info, the VPN server is 192.168.0.250 and receives its internet connection from my Netgear router 192.168.0.1. 192.168.0.250 is also configured as DMZ on the Netgear router. VPN server IP is configured statically and has a gateway of 192.168.0.1 towards the Netgear router.

VPN clients receive an IP between 192.168.0.130-150 and so are on the same subnet as the VPN server and Netgear gateway.

I have read that this setup, although unusual in the sense that only one NIC is being used, can work, and wondered if anybody had any quick fixes or suggestions.

Thanks for reading.
