 Chapter 6 Configuration Basics

ZyWALL USG 50 User’s Guide

Use trunks to set up load balancing using two or more interfaces.

Example: See 

Use policy routes to override the ZyWALL’s default routing behavior in order to 
send packets through the appropriate interface or VPN tunnel. You can also use 
policy routes for bandwidth management (out of the ZyWALL), port triggering, 
and general NAT on the source address. You have to set up the criteria, next-hops, 
and NAT settings first.

Example: You have an FTP server connected to P6 (in the DMZ zone). You want 
to limit the amount of FTP traffic that goes out from the FTP server through your 
WAN connection. 

Create an address object for the FTP server (Object > Address). 

Click Configuration > Network > Routing > Policy Route to go to the policy 
route configuration screen. Add a policy route.

Name the policy route.

Select the interface that the traffic comes in through (P3 in this example). 

Select the FTP server’s address as the source address.

You don’t need to specify the destination address or the schedule. 

For the service, select FTP.
