If an attacker forges the gateway address to send ARP packets with the source IP address being the IP address of the gateway on the LAN, ARP entries on hosts in the LAN record the incorrect gateway address. As a result, all traffic from user hosts to the gateway is sent to the attacker and the attacker intercepts user information. Communication between users is interrupted.

To defend against bogus gateways, you can enable the ARP gateway anti-collision on gateways.
