ZyXEL Communications ZyWALL 1000 User Manual

ZyWALL USG 1000 User’s Guide

This chapter describes how to set up addresses and address groups for the ZyWALL. See 

 for related information on these screens.

Address objects can represent a single IP address or a range of IP addresses. Address groups 
are composed of address objects and other address groups.
Address objects and address groups are used in dynamic routes, firewall rules, application 
patrol, content filtering, and VPN connection policies. For example, addresses are used to 
specify where content restrictions apply in content filtering. Please see the respective sections 
for more information about how address objects and address groups are used in each one.
Address groups are composed of address objects and address groups. The sequence of 
members in the address group is not important.

The address screens are used to create, maintain, and remove addresses. There are the types of 
address objects.

• HOST - a host address is defined by an IP Address.
• RANGE - a range address is defined by a Starting IP Address and an Ending IP 

Address.

• SUBNET - a network address is defined by a Network IP address and Netmask subnet 

mask.

There are two different screens, the Address summary screen and the Address Add/Edit 
screen.

The Address screen provides a summary of all addresses in the ZyWALL. To access this 
screen, click Object > Address > Address.
