Barracuda CloudGen Firewall


Barracuda CloudGen Firewall version 8.0 is a cloud-only version. It is currently not available for on-premises deployments and can only be deployed in Microsoft Azure, Amazon Web Services, or Google Cloud Platform public clouds.

Configuration Pages - Access and Controls

  • Last updated on

Expanding the configuration tree of the Barracuda CloudGen Firewall and Control Center provides access to the configuration objects. Double-clicking a configuration object opens the configuration pages section where you can modify the settings, depending on the box or server service. Barracuda Firewall Admin offers a set of useful tools for editing configuration sections, referencing network objects, exporting configuration files, etc.

Configuration Pages

A configuration object consists of an expandable configuration tree containing further objects, depending on the server or service, and the configuration pages. When accessing a page, the Configuration menu on the left provides links to the configuration sub-pages, and the Configuration Mode menu lets you switch from simple to advanced page view.


Every configuration page provides a set of editable sections, depending on the configuration requirements. The Help section on the right displays a description of each parameter and explains its functionality. A configuration page can consist of the following components:


A common configuration field takes a single entry, but it can also display a read-only setting. Some fields offer a list of selectable items. This is indicated by a dropdown arrow on the right. You can also copy entries (see Configuration Tools) and replace or merge them with entries previously copied to the clipboard. Some lists have an Other checkbox following them. Check it to override the list and type in the value manually.


Tables provide the option of adding and editing configurations (see Configuration Tools). When adding a configuration, pop-ups provide further options, such as entering name, description, settings etc. Configurations are then displayed in the table in descending order.


Lists provide the option of adding single configuration entries by entering or selecting them from a pop-up. Clicking the Other option, if present, lets you add an explicit entry.

On the Barracuda Firewall Control Center, some lists provide the option to reference global network objects that are available for use in the configuration.

This is indicated by an icon (see Configuration Tools).

Clicking the Set Reference icon (ref01.png) opens a window that displays all valid single and referenced network objects that are available for use with the configuration.
The following network objects can be selected, if configured:

  1. Cluster- and box-specific private and public IP addresses, networks and network ranges, virtual IP addresses, and public ISP addresses that are configured on managed Barracuda CloudGen F Firewalls.
  2. Cluster- and box-specific IP addresses and networks that contain a reference or are part of a reference chain.

Clicking the Insert Reference icon (net03.png) opens a window that displays all valid single network objects that are available without an already existing reference.


To insert a network object, select the desired entry and click OK.

Configuration Tools

To add and modify tables and list entries, use the icons on the configuration pages. Configuration options are indicated as follows:

Icon Setting Description
clip.png Copy to clipboard /../ Show Entry History

This icon is available for all fields. It offers a context menu that allows interaction with the clipboard and provides a view of the file history.

Copy an entry, table, or list configuration to the clipboard / replace or merge with the clipboard by selecting the following options.

  • Copy to Clipboard – Copy a selected entry with the configuration properties to the clipboard. When you copy a setting, the configuration remains on the clipboard if not replaced by another copy.
  • Replace with Clipboard – Select this option to replace all the configuration settings to the state documented on the clipboard. Use this feature, for example, to revert a configuration entry or list to a previous working state.
  • Merge with Clipboard – Merge configuration entries with the clipboard when the clipboard contains additional settings. Entries on the clipboard are added to the present configuration together with their attributes, such as name, settings, etc.

    When merging entries from different releases, you must verify the working state by testing the configuration.

  • Show Entry History – Displays the RCS Report window with the configuration file history of the selected entry.

net02.png Insert Reference

Set a reference to a single network object. This can be a cluster- or box-specific IP address, a network or network range, a virtual IP address, or a public ISP address that is configured on a managed Barracuda CloudGen Firewall. This option allows you to create a list of referenced network objects.
