Resolved: firewalld service reports the errors when the Plesk Firewall is installed

If you have been coming across the following error while trying to check the firewalld service status, you have come to the right place. Our Support Techs have been helping our customers overcome the same issue.

# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled;
...
example.com firewalld[20760]: WARNING: COMMAND_FAILED: '/usr/sbin/iptables -w2 -w --table filter --delete FORWARD --source 192.0.2.2/24 --in-interface virbr0 --jump ACCEPT' failed:

In this scenario, the Plesk Firewall will be marked as installed. We can check this by navigating to Plesk extensions, under Add Remove Components in the Updates & Upgrades section under Tools & Settings. We will see a check in the box next to Plesk FIrewall as seen in the image below:

As a result of the WARNING: COMMAND_FAILED error, we will not be able to use firewalld service and Plesk Firewall at the same time.

Fortunately, our Support Team has been able to come up with a workaround for the issue:

1. First, connect to the server with the help of SSH.
2. Next, execute the following commands to disable the firewalld service.

   # systemctl stop firewalld
   
   systemctl disable firewalld
3. Then, reapply the rules by restarting Plesk Firewall with the following command:

   # systemctl restart psa-firewall
