When you use this interface, you can generate a default route on the ha
configuration. The behavior that I noticed is: when a fortigate
initiates all the interfaces are down, except management one, so every
route on the routing table will be useless ...
I resolved this. You must use the dedicated management interface ALWAYS,
so the fortigate can contact dns server and azure. The dedicated
interface doesn't depend from the azure and SDN algorithm so it works.
