Support Tunnel

When Barracuda Technical Support needs to troubleshoot a Barracuda Backup appliance, the technician uses a support tunnel to remotely connect to that appliance.

Barracuda appliances connect to the Barracuda Support Server located at this address:

  • term.cuda-support.com:22 – support tunnel

When opening the support tunnel, the Barracuda appliance attempts to connect directly to the Barracuda Support Server term.cuda-support.com on port 22.

Open your network to allow the Barracuda appliance outbound access to ALL on port 22.

You must have a valid external DNS to resolve support tunnel DNS entries.

For more information on required outbound connections, refer to Required Outbound Connections for Barracuda Appliances.

Open a Support Tunnel through the Web Interface

Use the following steps to open a support tunnel through the Barracuda Backup web interface:

  1. Log into https://login.barracuda.com/, and select the appliance in the left pane.
  2. Go to System > Troubleshooting page, and click the toggle to Open a support tunnel.
  3. Click Open.
  4. Once troubleshooting is complete, click the toggle to Close and disable the support tunnel.
Open a Support Tunnel Using the Console

You can alternatively use the console screen on the Barracuda Backup appliance to open a support tunnel.

To access and interact with the console screen, you need a VGA Monitor and USB or PS/2 keyboard.

Use the following steps to open a support tunnel using the console:

  1. Connect the VGA monitor and keyboard to the Barracuda Backup appliance.
  2. Use the keyboard arrows to highlight Troubleshooting, and press either Enter or the right arrow key on your keyboard to move the cursor to the Troubleshooting menu:
