CHAPTER 34 Addresses 34.1 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. 34.1.1 What You Can Do in this Chapter • The Address screen (Section 34.2 on page 555) provides a summary of all addresses in the ZyWALL. Use the Address Add/Edit screen to create a new address or edit an existing one. • Use the Address Group summary screen (Section 34.3 on page 558) and the Address Group Add/Edit screen, to maintain address groups in the ZyWALL. 34.1.2 What You Need To Know Address objects and address groups are used in dynamic routes, firewall rules, 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. • See Section 6.6 on page 103 for related information on these screens. • See Section 7.12 on page 145 for how to create a public IP address range object for using multiple static public WAN IP addresses for LAN to WAN traffic. 34.2 Address Summary Screen 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. ZyWALL USG 20/20W User's Guide 555
