The Configuration page of the Barracuda NextGen Control Center lets you configure the Barracuda NextGen Control Center. It also lets you remotely configure the managed Barracuda NextGen Firewall F-Series units. To access the Configuration page, click the Configuration tab in the ribbon bar.
The main display of the Configuration page consists of two frames:
- Configuration Tree (left) – Lists all configuration pages in hierarchical order.
Tabs Section (right) – Provides information related to configuration nodes and units. In case this section is not visible, move your cursor to the right of the window and drag the section to the middle of the screen.
The configuration tree displays all configuration pages, just like on the Barracuda NextGen Firewall. The Multi-Range node represents the highest level within the hierarchy and contains all available ranges, clusters, and boxes that are managed by the Control Center. From here, you can manage your configurations and administrative sessions. You can also identify which nodes have been modified. To access the sub-pages of a configuration section, click + (expand).
When you right-click the nodes of the configuration tree, you are provided with the following options:
- Collapse All – Closes all open nodes in the configuration tree down to the top level.
- Properties – Opens a window that displays the properties of the configuration node.
Lock – Locks write access to the selected node or tree branch. A lock icon is then displayed next to the node or branch. This lets other administrators know that the page has been locked for editing. If a page has been locked by you, a yellow lock is displayed next to it. If a page is locked by another administrator, a gray lock is displayed next to it.
Selecting Show Lock Info from the context menu displays information on the administrator who has locked the selected node or tree branch. Break Lock breaks the lock held by another administrator on the selected node or tree branch. Unlock releases write access to the configuration page. It is recommended that you unlock all configuration files before quitting a session or starting another task.
To prevent administrators from overwriting each other's changes, you can only break locks that belong to broken sessions that are older than 10 minutes. An active session is broken when the associated client is suddenly disconnected and cannot successfully reconnect. You cannot break locks held in active sessions. However, if you have the appropriate permissions, you can kill sessions that own the lock.
