You can create custom groups for source IPv4 addresses by specifying individual, subnet, or range of addresses.

Custom groups for IPv6 addresses are not currently supported.

To create a custom group for source IPv4 addresses:

1. Go to Policies > Access Control > Firewall > IP & FQDN Groups.
2. In the Source IPv4 Groups tab, click Add Source IPv4 Group.
3. Enter a Name for the source IPv4 address group (e.g., Social Media). Only alphanumeric characters, underscores, hyphens, and periods are allowed.

4. Enter any number of IPv4 addresses. You can enter:

   • An address (e.g., 198.51.100.100)
   • A range of addresses (e.g., 192.0.2.1-192.0.2.10)
   • An address with a netmask (e.g., 203.0.113.0/24)

   You can enter multiple entries. Press Enter after each entry, then click Add Items. For item lists, you can view up to 500 items on a page; filter the list by searching for a word, phrase, or number contained in an item; and remove all items from the list (Remove All) or only items from a specific page (Remove Page). If you select Remove All or Remove Page, a confirmation window appears.

5. (Optional) Enter additional notes or information. The description cannot exceed 10,240 characters.
6. Click Save and activate the change.
