Firewall (ISPmanager)
From ISPWiki
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.
For more information, please read Firewall. Technical details (ISPmanager) and ISPmanager Troubleshooting.
This module is specially designed to manage the network connections and create Firewall rules that allow connections to the services. You may add the service's filters to accept or deny connection to certain IP-addresses.
