Abstract
The present invention provides a dynamic network address translation system and method of transparent private network device. With the NAT approach, the first device in a public network can be connected to a second device in a private network. The first packet for the connection is sent from the first device in the public network to the second device in the private network. Before establishing the connection, the first device exchanges information between the NAPT router of the private network. The NAPT router maintains its translation table according to the information. Then, the first device sends a connection request to a specific port of the NAPT router, and the packet will be transformed and routed properly to the second device.
