17.2.1 The Inbound LB Add/Edit Screen

The Add DNS Load Balancing screen allows you to add a domain name for which the ZyWALL
manages load balancing between the specified interfaces. You can configure the ZyWALL to apply
DNS load balancing to some specific hosts only by configuring the Query From settings. Click
Configuration > Network > Inbound LB and then the Add or Edit icon to open this screen.

Query From Address

This field displays the source IP address of the DNS query messages to which the
ZyWALL applies the DNS load balancing rule.

Query From Zone

The ZyWALL applies the DNS load balancing rule to the query messages received
from this zone.

Load Balancing Member This field displays the member interfaces which the ZyWALL manages for load

balancing.

Algorithm

This field displays the load balancing method the ZyWALL uses for this DNS load
balancing rule.

Weighted Round Robin - Each member interface is assigned a weight. An
interface with a larger weight gets more chances to transmit traffic than an interface
with a smaller weight. For example, if the weight ratio of wan1 and wan2 interfaces
is 2:1, the ZyWALL chooses wan1 for 2 sessions’ traffic and wan2 for 1 session’s
traffic in each round of 3 new sessions.

Least Connection - The ZyWALL chooses choose a member interface which is
handling the least number of sessions.

Least Load - Outbound - The ZyWALL chooses a member interface which is
handling the least amount of outgoing traffic.

Least Load - Inbound - The ZyWALL chooses a member interface which is
handling the least amount of incoming traffic.

Least Load - Total - The ZyWALL chooses a member interface which is handling
the least amount of outgoing and incoming traffic.
