Chapter 9 WAN Screens Figure 101 Weighted Round Robin Algorithm Example To load balance using the weighted round robin method, select Weighted Round Robin in the Load Balancing Algorithm field. Figure 102 Load Balancing: Weighted Round Robin The following table describes the related fields in this screen. Table 39 Load Balancing: Weighted Round Robin LABEL DESCRIPTION Active/Active Mode Select Active/Active Mode and set the related fields to enable load balancing on the ZyWALL. Load Balancing Set the load balancing method to Weighted Round Robin. Algorithm WAN Interface to Local Host Mapping Timeout Select this option to have the ZyWALL send all of a local computer's traffic through the same WAN interface for the period of time that you specify (1 to 600 seconds). This is useful when a redirect server forwards a local user's request for a file and informs the file server that a particular WAN IP address is requesting the file. If the user's subsequent sessions came from a different WAN IP address, the file server would deny the request. Interface This field displays the name of the WAN interface (WAN 1 and WAN 2). Ratio Specify the weight for the interface. Enter 0 to set the ZyWALL not to send traffic load to the interface. The higher the number, the bigger the weight (the more traffic sent). 9.2.5 Spillover With the spillover load balancing algorithm, the ZyWALL sends network traffic to the primary interface until the maximum allowable load is reached, then the ZyWALL sends the excess network traffic of new sessions to the secondary WAN interface. Configure the Route Priority metrics in the WAN General screen to determine the primary and secondary WANs. 180 ZyWALL 5/35/70 Series User's Guide
