CHAPTER 35
Addresses
This chapter describes how to set up addresses and address groups for the ZyWALL. See
Section 5.5 on page 122 for related information on these screens.
35.1 Addresses Overview
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.
35.2 Address Screens
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.
35.2.1 Address Summary
The Address screen provides a summary of all addresses in the ZyWALL. To access this
screen, click Object > Address > Address.
