3.2.1.3. Component

The actual configuration of hosts is performed using configuration components. These components are bound to the specific firewall services. For example, there are separate components for Postfix (Mail transport), for NTP (Time) and for PNS itself. The list of usable components depend on the type of host under configuration. Most components belong to PNS firewall hosts.

By default, there are two components added for each host: Networking and Management Agent. For MS hosts the Management Server component is added automatically.

  2. Navigate to the Host tab, and under the Components in use section, click New.

  3. Select the configuration component to add from the Components available list.

    Note

    For managing PNS firewall hosts, it is essential to add the Application-level Gateway and the Management Access components, at the very minimum.

    The configuration components are strictly focused on the service they manage and all have a distinctive graphical management interface accordingly. For more information on the different components, see the respective chapters.
