1. A LAN system for causing a base station that is inside a LAN to determine whether or not to authenticate a terminal station outside of said LAN and to permit said terminal station to access a predetermined server or network-connected device when said terminal station has not been authenticated,wherein said base station comprises:

  • an interface portion for making a communication with said terminal station and extracting authentication request information and a reception packet therefrom;

    a first authentication managing portion for determining whether or not to authenticate said terminal station for said LAN corresponding to a response from an inner LAN authenticating server responding to said authentication request information received from said interface portion and setting a result of the determination to a first packet distributing table; and

    a first packet distributing portion for referencing registered contents of said first packet distributing table for the packet received from said interface portion, transferring the packet received from said interface portion to said LAN when said contents of said first packet distributing table represent that said terminal station has been authenticated for said LAN, and transmitting the packet received from said interface portion to said predetermined server or network-connected device when said contents of said first packet distributing table represent that said terminal station has not been authenticated for said LAN.
