Communication through network address translation (nat) devices

摘要

Communication between a first device having a non-routable address behind a network address translation (NAT) type of device (translator), and a second device, according to a protocol in which the first device embeds its non-routable address and a communication port within protocol data sent to the second device. Translation assigns an apparent origin and apparent port for the protocol data different from the non-routable address and embedded port. The second device is configured to identify the embedded non-routable data and utilise the apparent origin and apparent port.
