Wp Cerber isnt blocking but says so

Hi!

First, thank you for the plugin.

WP Cerber looks likes its running okay, and it even logs and says it blocks the ips (and subnets).

But even after saying that was blocked, I still continue getting hits from them.

How do WP Cerber blocks? Is there any way it can blocks via iptables/firewall also?

Thanks!
