Network address converting apparatus and storage medium

摘要

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.
