Barracuda Link Balancer

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

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

Answer:
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.
