Does anyone tried to change port for build-in OpenVpn server from 1194 to 443? I have some colleagues with openvpn and sip clients installed on smartphones. When they travel abroad, in some airports and hotels free WiFi networks port 1194 is closed very often but 443 is opened. So is possible to change it in FreePbx configuration?
You’re gunna want to set it up to use TCP instead of UDP as well. I’ve encountered situations where UDP over port 443 is blocked but TCP is not on some public WiFi.
