I did a restore from 13 to 16 after the server running 13 was having terrible errors. Everything seemed to restore fine, but I am having issues with the firewall since then. It acts like firewall loads and lets you put configurations in the gui, but it doesn’t actually seem to be working, therefore we are getting constant Fail2Ban hits. If you go to the firewall status page, the error it shows is “Firewall is not running! File:/var/www/html/admin/modules/firewall/Attacks.class.php:17”. Also, I went in the asterisk logfiles to the firewall.err and I’m seeing stuff like this:

Any help would be so appreciated!
