    Abstract: A data communication method between hosts belonging to different private networks having their own private address spaces, each of the private networks Including at least one network address translator (NAT) and a proxy server accessible from a public address space. The one host obtains an outside-accessible address of the other proxy server and sends a path-coupled signaling packet using the outside-accessible address toward the other proxy server. At the NAT which the path-coupled signaling packet passes in the private network to which the one host belongs, a public address is allocated to the one host. The allocated public address is sent to the other host, allowing the one host to receive data from the other host. When receiving a public address from the other host, data communication is made possible both an the one host and the other host.
