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