I am using FreePBX 15.0.29 with asterisk 16.13. I have enabled the Intrusion Detection Sync Firewall setting and is working without issues. However, from time to time I turn on the responsive firewall to allow a remote endpoint to register and the IP address is added to the Registered Ext. IP list. How do I remove an IP address from this list? I can remove IP addresses from lists I manually entered to a zone. I have remote endpoints with dynamic IP addresses that have changed often.
