CHAPTER 5
Configuration Basics
This section provides information 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.
• Section 5.1 on page 111 introduces (very briefly) how granular the configuration is in the
ZyWALL.
• Section 5.2 on page 112 introduces some differences in terminology and organization
between the ZyWALL and other routers, particularly ZyNOS routers.
• Section 5.3 on page 112 explains the differences between physical ports, interfaces, and
zones in the ZyWALL.
• Section 5.4 on page 114 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.)
• Section 5.5 on page 122 identifies the features (such as the criteria in a policy route,
mentioned above) that are primarily used to store information used by other features.
• Section 5.6 on page 123 introduces some of the tools available for system management.
5.1 Granular Configuration
ZyWALL configuration is granular. When you configure a feature, you can often reuse
settings that you have already configured (in one screen) in other screens. These reusable
settings are called objects.
For example, when you set up a policy route, each criterion is an object. You can use criterion
that you have already configured or select Create Object to configure new criteria. Any
objects that you create in this screen, you can reuse --without configuring them again--in other
policy routes or in other features such as firewall rules or service control.
For a list of common objects, see Section 5.5 on page 122.
