The Grouped Networks option allows users to define their own grouping of IP addresses, which can be used for creating firewall rules and outbound policy rules.
Instead of creating many individual policies based on a single IP address, a single policy can be created that is assigned to a particular Grouped Network.
To create a Grouped Network select Add Network Group.
A new window opens:
Add the group name and IP ranges and click Save.
The new Grouped Network can now be selected from the Group Policy and Firewall Rules “source” and “destination” options.
