Security policies are VDOM-specific. This means that all firewall settings for a VDOM, such as firewall addresses and security policies, are configured within the VDOM.
In VDOMs, all firewall related objects are configured per-VDOM including addresses, service groups, security profiles, schedules, traffic shaping, and so on. If you want firewall addresses, you will have to create them on each VDOM separately. If you have many addresses, and VDOMs this can be tedious and time consuming. Consider using a FortiManager unit to manage your VDOM configuration — it can get firewall objects from a configured VDOM or FortiGate unit, and push those objects to many other VDOMs or FortiGate units. See the
FortiManager Administration Guide.
