摘要： The present invention relates to a network system, the network system of the present invention comprises an authorized client terminal which is connected to a network, a server which is connected to the network, and a firewall which is interposed between the server and the network. The client terminal accesses the server by means of a publicly known protocol via a port having a publicly known port number in the firewall. In the case in which the accessing client terminal is authorized, the server downloads program for realizing effective dedicated protocols solely between the client terminal and itself to the client terminal via the port having the publicly known port number. Furthermore, the server access with the client terminal conducts data communication by executing the program and by means of the dedicated protocols, via the network and the port having the publicly known port number.
