FortiGate VDOM Link problem

[netview]

Hello,

I'd like to create a Link between 2 vdoms:

1. VDOM root

--HW_Switch_1

  --vlan 1 untagged(native)

  --vlan 5 tagged

2. VDOM PUBNET

--HW_Switch_2

  --vlan 5 untagged(native)

I'd like to link VDOM root -> Vlan5 Tagged TO VDOM PUBNET HW_Switch_2 directly

The usecase is that clients in VDOM root use dhcp and webaccess from VDOM PUBNET, but are authorized via VDOM root.

Its quite simple to create this transparent bridge via a hardware swich, but I want to create a setup without an external switch.

Is this possible?
