A FortiDDoS device is connected between a protected server and an Internet router. For the aggressive aging feature, the administrator must manually add the router internal interface MAC address to the FortiDDoS configuration. Why does the FortiDDoS need this information?
To send RST packets to the protected server spoofing the router internal interface MAC address.
To allow incoming traffic only from that specific MAC address.
To determine which traffic direction is incoming and which traffic direction is outgoing.
To allow outgoing traffic only to that specific MAC address.
