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.

If your server is in "server mode" you also need to fiddle with IPTables. Install the port opener that might end up in the "Unknown" section of the server-manager and open UDP/1194.
