I am trying to find some guidance on setting up and securing remote extensions. The best piece of documentation I found was this
The problem with using this as a guide is that it does not allow for Configuration File updates, Firmware Updates, and VPN cert updates after the initial setup. Also it does not allow for full initial remote provisioning.
It would appear that the only way I can get full support for remote extensions is to put my PBX in a DMZ or forward all the required ports from my public IP. Being brand new to FreePBX I don’t have skills to monitor for security issues and want to keep things as simple as possible initially. I am using Sangoma’s phones and was hoping the Zero Touch Configuration might offer help with secure remote provisioning but that does not appear to be the case. I would appreciate any thoughts or comments
