ZyWALL (ZLD) CLI Reference Guide

File server C finds that the request comes from WAN2’s IP address instead of WAN1’s IP address 
and rejects the request.

If link sticking had been configured, the ZyWALL would have still used WAN1 to send LAN user A’s 
request to file server C and the file server would have given the file to A.

The following table lists the ip load-balancing link-sticking commands for link sticking. (The 
link sticking commands have the prefix ip load-balancing because they affect the ZyWALL’s load 
balancing behavior.) You must use the 

configure terminal

 command to enter the configuration 

mode before you can use these commands. See 

 for details about the values 

you can input with these commands.   

This example shows how to activate link sticking and set the timeout to 600 seconds (ten minutes).
