I am testing out STUNner as a solution for call signalling.
I have a service set up that intercepts stun.domain.com on UDP port 3478.
Calls succeed while connected to Wifi on android, but if I connect to openziti through only mobile data, calls do not connect.
I think I need something that allows 192.168.0.0/16 (for LAN) and 10.0.0.0/16 with the port range 32769-65535 to connect to each other.
