<p>The present invention provides a tunneling apparatus which can perform tunneling without requiring the network to be suspended or requiring the existing configuration of a local network to be modified. The frame sorting part 11 determines whether or not a frame input from a local network through a physical interface is an encapsulated tunnel frame. If such frame is a tunnel frame, the frame sorting part 11 outputs such frame to the decapsulation unit of the tunneling part 13. If such frame is not a tunnel frame, the frame sorting part 11 outputs such frame to at least one of the address resolution unit of the kernel part 12 and the encapsulation unit of the tunneling part, based on the characteristics of such frame.</p> |
