Abstract
A gateway apparatus (100) is capable of connecting to an internal network (10) and an external network (50), and includes an information management unit (120) for managing a global IP address of the gateway apparatus and identification information for a device to be permitted to connect to the internal network. The information management unit transmits the global IP address and the identification information over the external network to an external apparatus. In response to a request received over the external network, the information management unit transmits a one-time password over the external network to the external apparatus. The gateway apparatus further includes: a connector unit (130) permitting the device to connect to the internal network, when it receives a URI containing the global IP address and the one-time password from the device to be permitted to connect over the external network; and an address converter unit (140) for converting between an IP address for the external network into an IP address for the internal network and converting an IP address for the internal network into an IP address for the external network.
