Configure the Barracuda Control Server from the Web Interface

Verify the system accessing the web interface is connected to the same network as the Barracuda Control Server, and that the appropriate routing is in place to allow connection to the IP address of the Barracuda Control Server via a web browser.

To configure administrative settings on the Barracuda Control Server:

  1. From a web browser, enter http:// followed by the IP address of the Barracuda Control Server, followed by the default Web Interface HTTP Port. For example, type:
  2. Log in to the Barracuda Control Server using the Barracuda Control Server Administrator Account (admin/admin).
  3. Go to the BASIC > IP Configuration page, and perform the following steps:
    • In the TCP/IP Configuration section, verify the IP address, netmask, default gateway for your Barracuda Control Server.
    • Verify the primary and secondary DNS servers for your Barracuda Control Server.
    • Enter the default hostname and default domain name of the Barracuda Control Server.
    • If you want to configure a proxy server to allow access to the internet, enter the proxy server details in the Proxy Server Configuration section.
    • Enter the Default Domain, for example, <>.
    • Enter an externally resolvable system name (FQDN) for the Barracuda Control Server in the External System Name field.
  4. Click Save Changes.

    Whenever your Barracuda Control Server IP address is changed on the IP Configuration page, you are disconnected from the administration interface. You must log in using the new IP address.

Activate Subscriptions

After installation, your Energize Updates and other optional subscriptions must be activated to fully enable the Barracuda Control Server and to continue receiving the latest updates to all virus, policy, and document definitions from Barracuda Central. The Energize Updates service is responsible for downloading these updates to your Barracuda Control Server.

Proxy Server Configuration

  3. Click on the designated link to open the Product Activation page in a new browser window.

  4. On the Product Activation  page, fill in the required fields and click Activate. A confirmation page opens and displays the terms of your subscription.

  5. If the Energize Updates status is Not Activated, click the activation link to go to the Barracuda Networks Product Activation page and complete your subscriptions activation.

  6. If your Barracuda Control Server cannot communicate directly to Barracuda Central servers, an Activation Code displays; enter this code in the Activation Code field, and click Save to activate your Barracuda Control Server.

  7. Return to the Barracuda Control Server administration interface and navigate to the BASIC > Dashboard page. In the Subscription Status section, verify that the status displays as Current.

  8. There may be a slight delay of a few minutes for the display to reflect your updated subscription status. If the status continues to display as Not Activated, click Refresh  in the Subscription Status section. 

If your subscription status does not change to Current within an hour, or if you have trouble filling out the Product Activation page, contact your Barracuda Networks sales representative.
