The High Availability option allows you to link two Barracuda Link Balancers as a clustered active/passive pair. Both systems connect to the WAN links, but only one actively processes traffic at any time. The two systems continuously share most configuration settings and monitor one another’s health. If clustering two Barracuda Link Balancers is not an option, as an alternative, consider configuring Ethernet Passthrough. (This feature is only available on certain models.)
