摘要： An apparatus translates a destination address of a first packet that is transferred from an external communication device in an external network to an internal communication device in an internal network through the external network, from an external-network address that has been assigned to the internal communication device using an addressing scheme for the external network, to an internal address that has been assigned to the internal communication device using an addressing scheme for the internal network. The apparatus transmits, to another apparatus, address information including the external-network address and identifier information for identifying the external communication device where the another apparatus is configured to translate a source address of a second packet that is transferred from the internal communication device to the external communication device, from the internal address to the external address.
