DESCRIPTION
Select the zone of DNS query messages upon which to apply this rule.
Select a load balancing method to use from the drop-down list box.
Select Weighted Round Robin to balance the traffic load between interfaces based on
their respective weights. 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 Zyxel Device chooses wan1 for 2 sessions' traffic and
wan2 for every session's traffic in each round of 3 new sessions.
Select Least Connection to have the Zyxel Device choose the member interface which is
handling the least number of sessions.
Select Least Load - Outbound to have the Zyxel Device choose the member interface
which is handling the least amount of outgoing traffic.
Select Least Load - Inbound to have the Zyxel Device choose the member interface
which is handling the least amount of incoming traffic.
Select Least Load - Total to have the Zyxel Device choose the member interface which is
handling the least amount of outgoing and incoming traffic.
Enter an alternate IP address with which the Zyxel Device will respond to a DNS query
message when the load balancing algorithm cannot find any available interface.
Click this to create a new member interface for this rule.
Double-click an entry or select it and click Edit to open a screen where you can modify
the entry's settings.
To remove an entry, select it and click Remove. The Zyxel Device confirms you want to
remove it before doing so.
This field displays the order in which the Zyxel Device checks this rule's member
interfaces.
This field displays the IP address of the member interface.
This field displays the name of the member interface. The Zyxel Device manages load
balancing between the member interfaces.
This field is available if you selected Weighted Round Robin as the load balancing
algorithm. This field displays the weight of the member interface. An interface with a
larger weight gets more chances to transmit traffic than an interface with a smaller
weight.
Click OK to save your changes back to the Zyxel Device.
Click Cancel to exit this screen without saving.
