Creating Addresses or Address Groups

Before You Begin

Procedure

Use the Addresses page to create addresses and address groups. Addresses and address groups are used in firewall and NAT services. After you create an address, you can combine it with other addresses to form an address group. Address groups are useful when you want to apply the same policy to multiple services.

To create an address or address group:

  1. Select Configure > Shared Objects > Addresses.

    The Addresses page appears.

  2. Click on the add icon (+).

    The Create Addresses page appears.

  3. Complete the configuration according to the guidelines provided in Table 280 and Table 281.
  4. Click OK to save the changes. If you want to discard your changes, click Cancel instead.

A new address or address group with your configurations is created. You can use this object in firewall or NAT policies.
