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

Update server

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.

A
tries to retrieve the file from file server
C
, the request goes through
WAN 2.

File server

finds that the request comes from WAN 2’s IP address instead of WAN 1’s
IP address and rejects the request.
