摘要
PURPOSE: A port forwarding setting method, a terminal device using the same, and a network system thereof are provided to observe data obtained by another network terminal device by using a list about a network terminal device. CONSTITUTION: A user terminal device requests data about a network terminal device(S510). A main network terminal device confirms a received request signal(S520). The main network terminal device transmits the obtained data to the user terminal device(S530). The main network terminal device confirms other sub network terminal devices(S540). The main network terminal device determines the existence of the sub network terminal devices providing requested data(S550). An error message is transmitted to the user terminal device(S560). A data request signal is transmitted to the sub network terminal devices(S570). The main network terminal device retransmits the transmitted data to the user terminal device(S580,S590).
