I am relly confuse when activating and using vpn so complext ,,, using certificate ect...ect.... I just want the simple one. so I am plant using direct port foward. what about my config rule ?
For security reason, I would not open any access to configuration from the outside. However, you can setup the OpenVPN and remote into your local network and access the EFW.
Also, be sure to check the Firewall > System Access to make sure your OpenVPN subnet has access to EFW Config.
