Occasionally a remote Agent will lose internet access and then our Fail2Ban will ban their IP address as their remote phone tries to re-establish its connection to the PBX.
To clear the phone from the Fail2Ban list of Banned IP addresses:
a. I would prefer not to add the banned Agent’s IP address to the "Whitelist"
b. I tried selecting “Restart” of the Intrusion Detection module from within the FreePBX GUI, but 15 seconds after the restart the remote agent’s IP address appears again in the Banned IP address list.
c. After about 1-3 hours the banned IP address stops appearing on the Intrusion Detection list of Banned IP addresses.
What is the proper way to immediately clear a banned IP address so that the Max Retry is reset for that IP address?
