Scope:
This applies to all Barracuda Networks products.
Answer:
The administration interface of the Barracuda Networks products can be secured to prevent access from any location that is not specified in the Administrator IP/Range. Follow these steps to add IP ranges to this list:
- Navigate to the Basic > Administration page of the Barracuda's Web user interface.
- Locate the Administrator IP/Range heading on the page.
- Input the IP and netmask for the range to be allowed to administer the Barracuda unit. A netmask of 255.255.255.255 will lock the administration privileges down to a single IP address.
