object-group creation and mapping it as group-object in AFM

Simply reference another list (address/port) e.g.:

create security firewall address-list test_example address-lists add { allowed_subnets_1 allowed_subnets_2 }

create security firewall port-list test_example port-lists add { allowed_ports_1 allowed_ports_2 }

You can also mix items with other lists e.g.:

create security firewall address-list test_example address-lists add { allowed_subnets_1 allowed_subnets_2 } addresses add { 172.16.1.1 }

create security firewall port-list test port-lists add { allowed_ports_1 allowed_ports_2 } ports add { 80 8080-8090 { description "Web Services"} }
