How do I setup the Link Balancer to balance inbound connections?

All Barracuda Link Balancer models, firmware version 1.2 and above.

Inbound link balancing and failover are available only if the Barracuda Link Balancer acts as an Authoritative DNS server for domains behind it.

When the Barracuda Link Balancer receives a DNS query for a hosted domain, it returns the IP address of a WAN link, which the client then uses to reach the hosted domain. The algorithm used to select the returned WAN link is the same as that used to select a link for outbound traffic.

Instructions for setting up Authoritative DNS can be found in Solution #00004131.
