An address translation method for a LAN (local area network) node using a real Internet protocol (IP) address to deliver and receive transparent application layer packets. First, the IP address of the local node equivalent to the WAN IP address of the router is assigned. Thereafter, the router masquerades ARP responses when the local node looks up MAC addresses of certain destinations, and rewrites the data-link layer header of packets transferred to and from the local node, such that application layer communications are deemed transparent.
