How to Restore the Firewall Configuration when Replacing Hardware Firewall Models

In case your Barracuda CloudGen F-Series Firewall is replaced (RMA or cold spare) with the same firewall model of the same or a newer revision, you must re-image or update the new firewall to the same firmware version and restore the configuration from a configuration backup (PAR file).

Before You Begin

• You must have a working PAR file of the previous configuration. For information on how to back up and restore configurations, see Backups and Recovery.
• The new hardware firewall or Control Center appliance must be running the same firmware version. Either update or reimage the firewall. For more information, see How to Recover a CloudGen F-Series Firewall or Control Center Appliance with a USB Flash Drive.

Step 1. Restore the Configuration on the New Firewall

1. Go to CONFIGURATION > Configuration Tree.
2. Right-click Box and select Restore from PAR file.

Step 2. (Barracuda Firewall Control Center C400 / C610 only) Configure the Fallback Module

Verify that a fallback interface is specified. If not, enable a fallback interface and select the fallback module name.

1. Go to CONFIGURATION > Configuration Tree > Box > Network.

2. In the left menu, select Interfaces.

3. Expand the Configuration Mode menu and select Switch to  Advanced View.
4. Click Lock.
5. In the Network Interface Cards section, edit the interface.  
6. Make sure that Fallback Enabled is set to Yes.
7. If the fallback module name is not specified:
   1. Select the fallback interface from the Fallback Module Name list:
      • Barracuda Firewall Control Center C400 – Select Intel PRO/1000 PCI-Express (82575/6).
        
      • Barracuda Firewall Control Center C610 – Select Intel PRO/1000 PCI-Express (82571/2/3/4 or 82566/7) .
       

   2. Click OK.

   3. ClickSend Changes and Activate.

Step 3. Select the Hardware Model

If the appliance revision of the new firewall differs from the previously installed version, you must adjust the Hardware Model . This is necessary because different hardware models typically come with newer network interfaces and thus require appropriate drivers.

1. Go to CONFIGURATION > Configuration Tree > Box > Box Properties > Identification.
2. Click Lock.
3. From the Hardware Model list, select the appropriate model revision.
4. Click Send Changes.
5. Go to CONFIGURATION > Configuration Tree > Box > Network > Interfaces. A pop-up window opens indicating that the hardware model must be changed.
    
6. Click OK to close the window.
7. Click Lock. The Appliance Model will now be automatically adjusted.
8. Click Send Changes and Activate.

Step 4. Activate the Network Configuration

1. Go to CONTROL > Box.
2. In the left menu, expand Network and click Activate new network configuration.
3. Click Activate now. The Activation Succeeded message is displayed after the network configuration has been activated.

During activation, the firewall displays a 'Reconnecting' message:

Barracuda Firewall Admin now automatically reconnects to the new management IP address. The new firewall is now running with the same configuration.
