Hello everyone, i'm going crazy with my current issue and need some advise from someone who knows 3cx Session border controllers and pfSense.
So, I have 1 PBX and 2 SBCs across 3 different sites. The PBX and 1 SBC are behind untangle firewalls and work just fine and dandy. The 2nd SBC, which is behind a pfSense firewall, cannot connect to the PBX, which stops the Yealink from registring with the PBX.
The SBC is using the same tunnel password of the first SBC and i have ports 5060 and 5090 forwarded on the pfSense, but i cannot tell if the ports are open or not?
What the heck am i missing?
