Chapter 18 DNS Inbound LB Table 159 Configuration > Network > DNS Inbound LB (continued) LABEL DESCRIPTION Query From Address Query From Zone Load Balancing Member Algorithm This field displays the source IP address of the DNS query messages to which the Zyxel Device applies the DNS load balancing rule. The Zyxel Device applies the DNS load balancing rule to the query messages received from this zone. This field displays the member interfaces which the Zyxel Device manages for load balancing. This field displays the load balancing method the Zyxel Device 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 Zyxel Device chooses wan1 for 2 sessions' traffic and wan2 for 1 session's traffic in each round of 3 new sessions. Least Connection - The Zyxel Device chooses choose a member interface which is handling the least number of sessions. Least Load - Outbound - The Zyxel Device chooses a member interface which is handling the least amount of outgoing traffic. Least Load - Inbound - The Zyxel Device chooses a member interface which is handling the least amount of incoming traffic. Apply Reset Least Load - Total - The Zyxel Device chooses a member interface which is handling the least amount of outgoing and incoming traffic. Click this button to save your changes to the Zyxel Device. Click this button to return the screen to its last-saved settings. 18.2.1 The DNS Inbound LB Add/Edit Screen The Add DNS Load Balancing screen allows you to add a domain name for which the Zyxel Device manages load balancing between the specified interfaces. You can configure the Zyxel Device 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. ZyWALL ATP Series User's Guide 415
