  • GATEWAY AND METHOD FOR AVOIDING ATTACKS
    Publication number: 20120278888
    Abstract: A gateway assigns an IP address included in an address list to a client in a local area network (LAN). The gateway inquires whether the assigned IP address is used by other clients in the LAN. The gateway records a media access control (MAC) address of the client and the assigned IP address in a mapping table when the assigned IP address is not used by the other clients in the LAN. The gateway transmits an address resolution protocol (ARP) request packet to the client, and determines whether an ARP response packet is received from the client. The gateway can determine that the client is an attacker if no ARP response packet is received from the client.
