Firewall blocking all traffic

After firewall activation phone calls, web page, SSH from internal or external network are not working.
Internal and external IPs were added to the trusted zones.
Also there are 2 errors

  1. Exception Firewall is not running! File:/var/www/html/admin/modules/firewall/Attacks.class.php:17
  2. Firewall Integrity Failed. Interface eth2 is not in the correct zone. This can be caused by manual alterations of iptables, or, an unexpected error. Please restart the firewall service.
    This system has only internal phones but I need external access to the Web GUI and SSH.
    Phone system is using subnet
    PBX server IP
    206.X.X.X - PBX’s external IP
    50.X.X.X - My external IP
    System Firewall
    Screenshots are attached.

Does anyone have any ideas how I can fix that?
