A firewall is hardware or software system that is configured to deny unauthorized access to certain services on your server while permitting authorized communications according to the specified rules. A rule defines which services will be allowed through your Firewall, and which ones will be kept out.

This module can be used to manage the network connections and create Firewall rules to accept or deny connections from specific IP-addresses.
