If you are running this server is "server-gateway mode" you now need to open port 1194 for UDP traffic as this is the default tunnel for OpenVPN. Now go into the Server Manager panel under port forwarding and forward UDP/1194 to "localhost". If your server is in "server mode" nothing needs to be done here.

You now need to add the VPN address range as a local networks in the server-manager under the Security section.
 +
 +
Router: IP address of the SME servers LAN net. I this example 192.168.1.1
 +
 +
The last thing you need to do before the installation is complete is to do a small change in the /etc/openvpn/openvpn.up file. Change the 192.168.1.1 value to match router you used when adding a local network.
 +
 +
When you have changed the file to match your network we start the service.
 +
 +
/etc/init.d/openvpn start
 +
 +
Verify that the service is running correctly by issuing an "ifconfig" and see the new "tap0" device
