Incoming calls being blocked. PFsense

[Mowser]

Hi Everyone,

Here my situation. I have a SIP trunk setup on FreePBX. This trunk allows me to dial out, and the call can be answered and there is outgoing audio. But, there is no incoming audio and incoming calls do not work.

I know that my error must be with PFSense, and I have setup all the NAT rules that I can find. I’m stuck on where to look now! Do I need to enable port forwarding for the incoming calls?

Any advice is greatly appreciated.
