allow management access to physical wan ports
Management access | FortiGate / FortiOS 7.0.0 | Fortinet Document Library
"Management access to the FortiGate will be limited to a single physical interface."
Foritgate 80E, has 2 WAN ports, but it is really not possible to access management GUI both public IP address on WAN1 and WAN2.
So far, I can access management GUI on WAN1 public IP address only.
