No Plesk Firewall rules are loaded after server reboot

Symptoms

No actual rules are present in iptables after server reboot on CentOS 7.2 and Ubuntu 12.04.

All rules were configured using Plesk Firewall extension.

fail2ban is also installed and enabled for auto start.

It is possible to find these errors in system journal:

 psa-firewall[975]: Another app is currently holding the xtables lock. Perhaps you want to use the -w option?
psa-firewall[975]: psa-firewall: failed to apply firewall configuration

Cause

fail2ban was not completely loaded when psa-firewall started applying iptables rules.Only one app can add rules to iptables at one time.

Bug PPPM-3993 . It is fixed in Plesk 12 MU #81, Plesk 12.5 MU #26 and Plesk Onyx .

Resolution

Install the latest microupdates or upgrade to the latest Plesk version .
