I have new FPBX 15 install I have just installed
PBX Distro: 12.7.8-2012-1.sng7
Asterisk Version: 16.15.1
When first booted fail2ban works fine. System is behind a router so I haven’t been using the firewall. I have fail2ban set to ban after 4 failed logons and this has protected my system fine.
Logs and bans quite a few IP’s, however after about 10 hours fail2ban stops adding banned IP addresses to the fire wall and the constant login attempts start to become a DOS attack. Restarting the fail2ban service makes no difference, only a complete reboot seems to help.
I compared the failban log files and settings with a sister system I have which working fine and can’t see any difference?
Has anyone had similar issues? or could give me a clue where to look next?
