ZyWALL 2WG User’s Guide

1 LAN user A wants to download a file from a remote server on the Internet. The 

ZyWALL is using active/active load balancing and sends the request to an update server 
(B) through WAN 1.

2 Update server B sends a file list to LAN user A. The download address of the desired file 

is a file server (C). At the same time, update server B informs file server C that a 
computer located at the WAN 1’s IP address will download a file.

3 When LAN user A tries to retrieve the file from file server C, the request goes through 

WAN 2.

4 File server C finds that the request comes from WAN 2’s IP address instead of WAN 1’s 

IP address and rejects the request.

To configure your WAN General settings click NETWORK > WAN to open the General 
screen.
