In FreePBX 184.108.40.206, fully updated, I have IPs that are whitelisted in firewall and fail2ban but occasionally wind up in fpbxblacklist. They are not listed as blocked in the firewall GUI or fail2ban. I have to find them with iptables -L | grep 220.127.116.11 then delete them.
How do IPs get in the chain fpbxblacklist ? Anyone know how to prevent this from happening?
