ZyWALL USG 1000 User’s Guide

This information is provided to help you configure the ZyWALL effectively. Some of 
it is helpful when you are just getting started. Some of it is provided for your 
reference when you configure various features in the ZyWALL.

•

 introduces the ZyWALL’s object-based configuration.

•

 introduces zones, interfaces, and port groups.

•

 introduces some differences in terminology and 

organization between the ZyWALL and other routers, particularly ZyNOS 

routers.

•

 covers the ZyWALL’s packet flow.

•

 identifies the features you should configure before and 

after you configure the main screens for each feature. For example, if you want 

to configure a trunk for load-balancing, you should configure the member 

interfaces before you configure the trunk. After you configure the trunk, you 

should configure a policy route for it as well. (You might also have to configure 

criteria for the policy route.)

•

 identifies the objects that store information used by 

other features.

•

 introduces some of the tools available for system 

management.

The ZyWALL stores information or settings as objects. You use these objects to 
configure many of the ZyWALL’s features and settings. Once you configure an 
object, you can reuse it in configuring other features. 

When you change an object’s settings, the ZyWALL automatically updates all the 
settings or rules that use the object. For example, if you create a schedule object, 
you can have firewall, application patrol, content filter, and other settings use it. If 
you modify the schedule, all the firewall, application patrol, content filter, and 
other settings that use the schedule automatically apply the updated schedule. 

You can create address objects based on an interface’s IP address, subnet, or 
gateway. The ZyWALL automatically updates every rule or setting that uses these
