Box Page

  • Last updated on

On the Box page, you can configure and control key aspects of the Barracuda NG Firewall box operation. To access the Box page, open the Control tab and click the Box icon in the ribbon bar.

The Box page is divided into the following sections:

Time

When expanded in the left pane, the Time menu shows the system time and provides you with the following options to view and configure the time settings for the Barracuda NG Firewall:

  • Get Time – Displays the current time and date on the Barracuda NG Firewall.
  • Show Settings – Displays the current NTP settings in the Report window..
  • Set Time – Changes the current time and date to the values selected from the time and date fields. If your Barracuda NG Firewall is synchronized with an external time server, this manual change is overwritten by the succeeding time synchronization.
  • Restart NTP – Restarts all NTP services.
  • Synchronize Time – Offers an option dialog to synchronize the time settings with an NTP server.

If the Using Time Server and Own IP settings are unspecified, the synchronization process binds to the firewall's primary management IP address. This method works well with a time server that is placed in the same network as the primary management IP address. For time synchronization with a public time server, enter the external IP address of the firewall into the Own IP field so that the time server's response is not blocked by the firewall.

Network

When you expand the Network menu, you are provided with the following options to verify, restart, and activate the network configuration of the Barracuda NG Firewall:

Verify active network configuration

This option checks the currently active network configuration for errors. The result appears in the Report window.

Restart active network configuration

This option shuts down and then restarts the currently active network configuration.

The server subsystem is unaffected by this procedure, but the server and services will be unavailable for a short time while the network shuts down and restarts.

Verify new network configuration

This option checks new network configurations for errors after they have been successfully sent. The result appears in the Report window.

Because changing the network configuration of a remotely controlled Barracuda NG Control Center is a critical operation, new configurations are not automatically activated until after they have been verified. If the new network configuration is flawed, you must correct the errors and then verify the configuration again. The newly received network configuration file is stored in /opt/phion/preserve/boxnet.conf.

Activate new network configuration

This option activates new network configurations after they have been successfully verified. You can activate the new network configuration in the following modes:

  • Failsafe – Failsafe network activation is the safest way to activate configuration changes. Always use this activation method on productive firewalls, e.g., to do the following:

    • Add and delete network interfaces.
    • Change network interface configurations.
    • Add and delete policy routes.
    • Delete direct and gateway routes.

With this mode, the firewall creates a backup file of the active network configuration. It then temporarily activates the configuration changes and verifies that the firewall can still be contacted via Barracuda NG Admin. If this verification is successful, the network is restarted so that the changes are activated permanently. If verification fails within the timeout defined in the Set Timeout field, the original network configuration is restored.

You might lose connection to the Barracuda NG Firewall, especially when activating network configuration changes via a VPN connection. This causes a connection verification failure between the firewall and Barracuda NG Admin. As a result, the original configuration is then restored. If you experience this issue, try using 'Force' network activation.

  • Force – Forced network activation immediately activates the new network configuration with a logical consistency check but without creating a backup file of the active network configuration.

Use forced network activation with due care.

  • Soft – Soft network activation can only be used after you add direct routes or gateway routes to an existing configuration.
    Do not use 'Soft' network activation for the following:
    • Adding or deleting source-based routes.
    • Permanently deleting direct or gateway routes. Direct and gateway routes that have been deleted with 'Soft' network activation are marked as wild on the Network Page page. To delete these types of routes, use 'Failsafe' network activation instead or restart the network. To restart the firewall, expand the Operating System menu.
    You can also use soft network activation after changing the VPN Point of Entry for a management tunnel on a Barracuda NG Firewall. In this case, you can verify the configuration change by going to the Live Page and checking the Destination IP on port 692.

Dynamic Networks

If dynamic network connections have been configured, you can control them with options (off, on, start, stop, restart, reset) from the Dynamic Networks menu. You can control the following types of network connections: 

  • xDSL
  • ISDN
  • DHCP (cable)-connections
  • UMTS
  • MGMT (box management) 
  • Tunnel connections

Operating System

From the Operating System menu, you can control the Barracuda NG Firewall. The menu provides you with the following options:

  • Reboot Box – Reboots the Barracuda NG Firewall. If the firewall is not easily accessible, use caution when using this option because some firewalls might have problems with BIOS settings and fail to reboot or get stuck on a lower layer.
  • Firmware Restart Shuts down and then restarts all servers and services belonging to the Barracuda NG Firewall subsystem, including the firewall engine. 

    All connections will be lost, including non-Barracuda proprietary services such as Secure Shell (SSHd) and Network Time Protocol (NTPd).

    Using this option is similar to running the /opt/phion/bin/phionctrl shutdown and /opt/phion/bin/phionctrl startup commands, except the control daemon itself is not stopped and started.

  • Shutdown Box Turns off the Barracuda NG Firewall.
  • Save current Config for ART Saves the current configuration of the Barracuda NG Firewall to the ART crash recovery OS. If the firewall must be reinstalled remotely, the firewall uses the current system configuration for the recovery process.
  • Install Update Installs the selected firmware updates, hotfixes, or patches. The update process can be triggered after the package is successfully uploaded to the unit.
  • Generate System Report Creates a system report.
  • Reset SMS Counter Resets the counter for the number of successive SMS commands that have been accepted by the interface.

Domain Control

From the Domain Control menu, you can register the Barracuda NG Firewall as a Windows domain member or view its domain registration status. The menu provides you with the following options:

  • Show Registration StatusDisplays the registration status of the Barracuda NG Firewall at a Windows domain.
  • Register at DomainRegisters the Barracuda NG Firewall as a Windows domain member at a domain controller. In the User Authentication window, enter the username and password for the user with the appropriate administrative rights to add the firewall to the domain. Before you can use this option, configure an Authentication service.
  • Register Proxy at Domain – Registers the HTTP Proxy at the Windows domain.

Authentication Level

You can specify the level of authentication that is required for non-interactive Barracuda NG Control Center logins and HA synchronization.

Authentication level changes are effective immediately.

After you expand the Authentication Level menu, you can select one of the following options:

  • No Authentication – Level -1; no authentication is required to send or retrieve configuration data.

    Use this option only when necessary and revoke it as soon as possible.

  • Check Key or IP address – Level 0; an IP address or key challenge is required. This option is still quite unsecure.
  • Check IP address – Level 1, still quite unsecure. 
  • Check Key – Level 2, still quite unsecure.
  • Check Key and IP address – Level 3, default setting. Do not change it unless you must temporarily lower the security level. A change might be required when either the IP addresses of the Barracuda NG Control Center or HA partner, or the key of the Barracuda NG Control Center change.

SCEP Control

You can view and configure SCEP settings. When you expand the SCEP Control menu, you can select the following options from the Cmd list:

  • Show Certificate Info – Displays information about the certificate retrieved by SCEP.
  • Save Certificate to Clipboard Exports the certificate to the clipboard (PEM).
  • Save Certificate to File Exports the certificate to a file (PEM).
  • Initiate Pending Request Starts the enrollment process immediately.
  • Force SCEP Update Starts an SCEP update.
  • Set SCEP Debug ON Turns SCEP debugging on. Additional debugging information is included in the SCEP log (Box > Control > SCEP).
  • Set SCEP Debug OFF Turns SCEP debugging off.
  • Set SCEP Password Prompt for the SCEP password. This option is available only if the SCEP password policy is set to Enter-Password-At-Box.

Report

The Report window displays the results of operations selected in the above sections. For example, if a new network configuration is sent to the Barracuda NG Firewall and has been verified, the Report window shows the results of the consistency check.
