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.
