We are deploying the latest Freepbx distribution (12.7.3-1707-2.sng7 ) and plan to use the embedded OpenVPN server for home office phones. There is already an OpenVPN access server in use for remote access, but not wanting to consume a license for phone and the convenience of configuration with built in server for phones drives me to run both. Unfortunately, the default port of 1194 is the port already in use. I can change the port in /etc/openvpn config file but that can be overwritten by a sysadmin pro update. Where is the proper location for a permanent change? That would seem to be a great addition to the settings tab.
