Figure 11-10 ARP Attack – Cheating Gateway 
As the above figure shown, the attacker sends the fake ARP packets of Host A to the Gateway, 
and then the Gateway will automatically update its ARP table after receiving the ARP packets. 
When the Gateway tries to communicate with Host A in LAN, it will encapsulate this false 
destination MAC address for packets, which results in a breakdown of the normal communication. 
 
Cheating Terminal Hosts 
The attacker sends the false IP address-to-MAC address mapping entries of terminal Host/Server 
to another terminal Host, which causes that the two terminal Hosts in the same network segment 
can not communicate with each other normally. The ARP Attack implemented by cheating terminal 
Hosts is illustrated in the following figure.
