The session-aware NAT traversal method is used to establish network communication between two hosts, wherein a first and a second host are located behind a first and a second NAT router, respectively. First, these hosts conduct a standard NAT traversal to establish a session. Then, the second host sends a registration request message to the first NAT router for session registration. Upon receiving the registration request message, the first NAT router generates a session ID for this session and replies to the second host. As the second host moves to a private network behind a third NAT router, the second host only needs to send a new registration request message with the session ID to the first NAT router. The first NAT router observes a new mapped address of the second host and allows inbound traffic from the new mapped address without further NAT traversal.
