Issue Plesk firewall

Hi. I get strange problem.
Here is my plesk firewall settings:



If I make server reboot - it unreachable after reboot, I can't connect using ssh, ping shows all packets as lost and etc.
So after some research I'm connecting using IP KVM and running command:

service psa-firewall restart

And all works again.
Why?
