To redirect all traffic from VPN clients through the VPN server, you have to configure NAT.

At this step I assume that you have OpenVPN configured properly, if not please refer to the manual http://community.openvpn.net/openvpn/wiki/Easy_Windows_Guide.

1. Enabling IP forwarding Press Windows+R and type:

regedit.exe

Now navigate to the:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters

and set

IpEnableRouter

to 1

2. Installing role Open ServerManager and click on Install role

3. Configuring NAT Open Routing and Remote access console from Administrative Tools, right click on your server local name and select

In a wizard click on Network address translation(NAT)
