You can see a list of all default and custom service groups.
You can combine custom and default services in the same group.
Create groups of services and then add a firewall rule to allow or block access for all the services in the group. A service can be a member of multiple service groups.
You can also add a new group, edit an existing group, add services to an existing group, or delete a group.
Default service groups can't be updated or deleted.
