host receives an unknown ACK packet, it sends a RST-ACK packet to the camouflaged IP address. If the camouflage IP exists, then the masked host will throw the Rst-ack packet away; If the masquerade IP address does not exist, the intermediary router sends a message to the attacked host that the ICMP destination cannot reach. If the fake ACK packet is to be sent to a non-existent attacked host, then an intermediary router to the corresponding camouflage IP address of the host to send an ICMP targ
