ARP Attack Cheating Gateway | TP-Link TL-SL5428E guide

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.

¾Cheating 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.
