Issue Description

I am facing a problem. When FreePBX is running in a VM, the phones work with each other without any problem, and the router gives IP addresses to all the phones.

The problem is that on my physical computer where I installed this FreePBX, I cannot ping the FreePBX IP address and I also cannot access the WebGUI.

Now when I run:

iptables -F

everything works fine. It works for a short time, then the firewall starts again and access gets blocked., when firewall starts then gives me this message:

Broadcast message from root@My-PBX (somewhere) (Sat Feb 21 04:47:59 2026):

Firewall Rules corrupted! Restarting in 5 seconds
More information available in /var/log/asterisk/firewall.log

Broadcast message from root@My-PBX (somewhere) (Sat Feb 21 04:48:09 2026):

Firewall service now starting.
