Introduction to Address Book

IP address is an important element for the configurations of multiple modules, such as policy rules, NAT rules and session limit rules. Therefore, system supports address book to facilitate IP address reference and flexible configuration. You can specify a name for an IP range, and only reference the name during configuration. Address book is the database in system that is used to store the mappings between IP ranges and the corresponding names. The mapping entry between an IP address and its name in the address book is known as an address entry.

Address Entry

System provides a global address book. You need to specify an address entry for the global address book. When specifying the address entry, you can replace the IP range with a DNS name. Interfaces of the configured IPs will be used as address entries and added to the address book automatically. You can use them for NAT conveniently. Furthermore, an address entry also has the following features:

• All address books contain a default address entry named Any. The IP address of Any is 0.0.0.0/0, i.e., any IP address. Any can neither be edited nor deleted.
• One address entry can contain another address entry in the address book.
• If the IP range of an address entry changes, system will update other modules that reference the address entry automatically.
