Abstract:
1. A method of a PPPoA (point-to-point (PPP) over asynchronous transfer mode (ATM)) spoofing function in an asymmetric digital subscriber line (ADSL) modem, comprising the steps of: forming a single network between a client personal computer (PC) and a network access server (NAS) by allowing the ADSL modem to make a PPP connection to the NAS when the client PC is booted, by allowing the NAS to transmit Internet protocol (IP) configuration information, including a global IP address, to a DHCP server of the ADSL modem through a PPP Internet protocol control protocol (IPCP), and by allowing the ADSL modem to transfer the IP configuration information received from the NAS to the client PC; forming a bridge by the ADSL modem between the client PC and the NAS and transferring IP packets between the client PC and the NAS; and allowing the NAS to withdraw the global IP address assigned to the client PC when one of the client PC and the ADSL modem is turned off.
