1. A wire and wireless network system, comprising:
- a terminal to transmit an initialization information message after being allocated a private Internet protocol (IP) address within a service area of a private network; and
a wire and wireless sharing device to allocate the IP address according to a request transmitted from the terminal, and when the initialization information message is transmitted by the terminal, the wire and wireless sharing device configures a port to be used by the terminal and transmits a configured port message to the terminal, with the port configured to connect the private network to an authorized Internet, thereby performing port forwarding to the terminal by the wire and wireless sharing device,wherein the terminal comprises;
a dynamic host configuration protocol (DHCP) client unit to request the wire and wireless sharing device for allocation of the private IP address;
a message transmitting unit to transmit the initialization information message and a life message to the wire and wireless sharing device;
a message receiving unit to receive the configured port message and a response message from the wire and wireless sharing device, the response message being received in response to the transmitted life message; and
a port configuring unit to configure the port according to port information provided by the configured port message transmitted by the wire and wireless sharing device.

Abstract
In a port forwarding configuration system and method for wire and wireless networks, when an Internet protocol (IP) is allocated according to a request from a wireless terminal of a private network and an initialization information message is transmitted by the terminal, a port to be used by the terminal is configured and a configured port information message is transmitted to the terminal so as to open a port for the terminal, thereby performing a remote connection of a user terminal to the wireless terminal through port forwarding.

12. A port forwarding configuration method of a wire and wireless network system, the method comprising:
-
requesting, by a terminal, a wire and wireless sharing device to allocate an Internet protocol (IP) address; allocating, by the wire and wireless sharing device, a private IP address according to a request transmitted from the terminal; transmitting, by the terminal, an initialization information message to the wire and wireless sharing device; configuring, by the wire and wireless sharing device, a port to be used by the terminal, with the port connecting a private network to an authorized Internet; transmitting, by the wire and wireless sharing device, a configured port information message to the terminal; receiving, by the terminal, the configured port information message from the wire and wireless sharing device; configuring, by the terminal, the port according to the configured port information message transmitted by the wire and wireless sharing device; transmitting, by the terminal, a life message to the wire and wireless sharing device; and receiving, by the wire and wireless sharing device, the life message and transmitting a response message of the life message to the terminal after checking a media access control (MAC) address of the terminal, wherein the life message is a message informing the wire and wireless sharing device that the terminal operates normally. - View Dependent Claims (13, 14)
