Filed: 2002-09-11
Abstract: PURPOSE: A gateway system and a method for processing packets therein are provided to achieve the communication between terminals in a gateway network and the Internet access of the terminals without modifying the existing network setup of each terminal. CONSTITUTION: A terminal transmits an ARP(Address Resolution Protocol) request packet to obtain the MAC address of its own default gateway in order to route the packets toward its own IP band and another IP band. Receiving the ARP request packet(S301), the default gateway compares the target IP of the terminal with its own IP(S302). In case that it is judged that the target IP is identical to its own IP, the default gateway transmits an ARP response packet(S303). However, if it is judged that the target IP is not identical to its own IP, the default gateway confirms whether the target IP address exists in an ARP cache table(S302,S304). In case that the target IP address is not in the ARP cache table, the default gateway transmits a proxy ARP response message and sets the target IP of the ARP request message as an ARP Sender IP. At the same time, the default gateway sets its own MAC address as an ARP target HA(Home Agent)(S306).
