Abstract: PURPOSE: An AP(Access Point) for providing a gateway function and a method for providing a wireless LAN(Local Area Network) are provided to connect an external Internet network to a mobile communication terminal without correcting environment setup information of the mobile communication terminal although a user of the mobile communication terminal moves a network band and offer a web service to the mobile communication terminal. CONSTITUTION: A wireless connection unit(110) sets network band information to receive all packet data transmitted from a mobile communication terminal(300) which connects through a wireless LAN in a state in which network environment setup information is not adjusted, and processes a data communication through a MAC(Medium Access Control) layer, a wireless physical layer and RF(Radio Frequency). A wired connection unit(120) sets network band information so that all packet data transmitted from the mobile communication terminal are not received, and processes the data communication through a wired physical layer. A control unit(130) transmits and receives a control signal, a connection state signal and a device valid signal, processes data conversion between the wired connection unit(120) and the wireless connection unit(110), and manages data transmission. An INET data processing unit(140) sets an IP(Internet Protocol) address of the wireless connection unit(110) as gateway information, and changes the direction of packet data to the wireless connection unit(110) without setting gateway information of an external public network. The INET data processing unit(140) mutually translates a network address of the mobile communication terminal(300) to one public IP address, and inputs external public network gateway information in real time in a packet data communication. The INET data processing unit(140) processes IP forwarding between the wireless connection unit(110) and the wired connection unit(120), provides a lookup request to an authorized one DNS(Domain Name Server), and processes a message traffic between a public network and a local network.
