A FortiGate administrator configures a Virtual Domain (VDOM) for a new customer. After creating
the VDOM, the administrator is unable to reassign the dmz interface to the new VDOM as the
option is greyed out in Web Config in the management VDOM.
What would be a possible cause for this problem?
The dmz interface is referenced in the configuration of another VDOM.
The administrator does not have the proper permissions to reassign the dmz interface.
Non-management VDOMs can not reference physical interfaces.
The dmz interface is in PPPoE or DHCP mode.
Reassigning an interface to a different VDOM can only be done through the CLI.
