Abstract: An automatic account generation system includes an account generator having an IP address and exhibiting an account management function, a printer and at least one apparatus capable of providing wireless Internet access. The Internet user access authentication information can be acquired and printed from the account generator via an input device of the printer. When a user inputs the Internet user access authentication information into a wireless access apparatus, such as a notebook or a PDA equipped with a WLAN card, he or she can automatically access the WLAN where he or she is located. Moreover, the present system is equipped with a payment apparatus that can be connected to the account generator, so that it can accept payment made, whether by cash or by credit card, for getting the Internet user access authentication information.

Abstract: A virtual subnet controller includes a subnet mapping table and a control unit. When the source and destination stations belong to a public network and a private network, respectively, the NAT protocol is used for converting the IP address of the data packet. After receiving the ARP request froma source station, the virtual subnet controller will respond with an ARP response, enabling the data packet transmitted from the source station.
