Chapter 8 WAN Screens
Table 35 Load Balancing: Weighted Round Robin (continued)
LABEL | DESCRIPTION |
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). |
|
|
To load balance using the spillover method, select Spillover in the Load Balancing Algorithm field.
Configure the Route Priority metrics in the WAN General screen to determine the primary and secondary WANs. By default, WAN 1 is the primary WAN and WAN 2 is the secondary WAN.

WAN Interface | Select this option to have the ZyWALL send all of a local computer’s traffic through |
to Local Host | the same WAN interface for the period of time that you specify (1 to 600 seconds). |
Mapping | This is useful when a redirect server forwards a local user’s request for a file and |
Timeout | 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. |
|
|
Time Frame | You can set the ZyWALL to get the measured bandwidth using the average |
| bandwidth in the specified time interval. |
| Enter the time interval between 10 and 600 seconds. |
|
|
Send traffic to | Specify the maximum allowable bandwidth on the primary WAN. Once this |
secondary WAN | maximum bandwidth is reached, the ZyWALL sends the new session traffic that |
when primary | exceeds this limit to the secondary WAN. The ZyWALL continues to send traffic of |
WAN bandwidth | existing sessions to the primary WAN. |
