Adding, Updating or Viewing WAN Link Configuration

Every WAN link that enters the Barracuda Link Balancer needs to be manually identified. This

information is provided by your Internet Service Provider. Use the

Basic > Links page to identify the

links. You can view the configuration information by moving your mouse over the port. To change

or add configuration information, click on the corresponding WAN port on the graphic or the expand

button in the Configure column.

Adding a New WAN Link

There are a few things to remember if you are adding one or more new WAN links to an already-

configured Barracuda Link Balancer. As already mentioned, all links must be configured using the

Basic > Links page.
