A push-type information service to a client located within a local network and having only a local IP address becomes possible via a network address converting apparatus. A network address conversion program implementing the network address converting process may be stored on a storage medium. When assignment of an Internet IP address to a client is requested by a host server, an IP address assigning unit assigns an Internet IP address to that client. An address conversion table producing unit produces an address conversion table describing the correspondence between the Internet IP address assigned to the client and the local IP address of the client. An address converter notifies the host server of the assigned Internet IP address. After that, if the host server sends data to the acquired Internet IP address, the address converter converts the destination of the data to the corresponding local IP address of the client by referring to the address conversion table.

Network address converting apparatus and storage medium

A wireless server system and method for communicating between a user terminal and Internet a wirelessly. It is based on a user terminal having a fixed terminal and a terminal unit so that an Internet connection can be made by way of the terminal unit to an appropriate wireless server. The system has at least one wireless server connected to Internet; and a plurality of wireless station devices connected to the wireless server, and the system communicates wirelessly with the terminal unit of the user terminal; wherein one wireless server within a district of communication range of the wireless station devices is designated as a home server for the terminal unit, and the fixed terminal receives data sent wirelessly from Internet by way of the terminal unit.
