I have installed FreePBX as an docker container (image: tiredofit/freepbx:latest). Everything is running smoothly. Created a SIP extension (1004) and installed ZOIPER.
Accountname: FreePBX 5160
Domain: 192.168.2.100:5160 (example IP)
Username: 1004
Password: test (not the real password
Registering … Registration Status OK
Now I want to access FreePBX from the outside with ZOIPER. I know this is not the most secure way, but I don’t want to introduce extra complications for now by implementing VPN etc.
Created a Firewall rule:
All IP’s from outside connecting on port 5160 go to port 5160 to IP 192.168.2.100.Created a new account on ZOIPER, using:
Accountname: FreePBX 5160
Domain: 77.132.1.2.100:5160 (my external IP))
Username: 1004
Password: test
Now registering gives a Request timeout (408). I am pulling my hair out, could it be that there is a extra firewall enabled on FreePBX refusing external addresses?
