Grouping services
To make it easier to add policies, you can create groups of services and then add one policy to provide
access to or block access for all the services in the group. A service group can contain pre-defined services
and custom services in any combination. You cannot add service groups to another service group.
To add a service group:
• Go to Firewall > Service > Group .
• Click New.
• Enter a Group Name to identify the group. This name appears in the service list used when you add a
policy.
The name can contain numbers (0-9) and upper and lower case letters (A-Z, a-z), and the special
characters - and _. Spaces and the @ character are not allowed.
• To add services to the service group, select a service from the Available Services list and click the right
arrow to copy it to the Members list.
• To remove services from the service group, select a service from the Members list and click the left arrow
to remove it from the group.
• Click OK to add the service group.
