Hi All,
I have the following setup:
Pfsense firewall with public IP in cloud > NAT port forward to FreePBX IP address via Tailscale VPN.
I am using Groundwire softphones on the public internet. I am trying to proxy almost through the cloud firewall for added security.
The soft phone works and can make calls, however when connected the audio channel does not work despite the fact the ports are correctly configured. I can see in pfsense that the audio ports are open, so the connection is obviously correct at least to establish a connection.
If I am connected to the local LAN, everything works fine. This is looking like a NAT issue.
Any ideas? I have tried to play around with the asterisk settings and adjusting the LAN to the public IP of the cloud firewall and also the IP of the Tailscale client.
Nothing appears to work. Any ideas?
Thanks.
