I am using FreePBX 12 on Asterisk 11.
I've gotten a few notifications of 50+ SIP attempts against one of my FreePBX boxes the past couple of days. Initially, I added this IP subnet into the IP Tables rules list to deny further connections, but I received a notification this morning that this same IP address was banned again after 97 SIP attempts, even though this IP address should already be banned. I checked my IP Tables rule list and this IP is listed in there.
Why would Fail2Ban say that it has banned an IP but that IP is still allowed connection attempts to my system?
I'm not sure if this matters but my machine is running SSH on port 20022 instead of the standard port.
Any feedback is appreciated! Thanks!
