PROBLEM TO BE SOLVED: To provide a routing device which allows a plurality of hosts in different private networks to communicate over the network.SOLUTION: A first network interface device connects a routing device to a local private network. A second network interface device connects the routing device to the Internet. A processing device allocates a virtual subnet to a remote routing device for a remote host in a remote private network, and acquires a virtual Internet Protocol (IP) address on the basis of the virtual subnet. The processing device receives a network packet from a local host in the local private network through the first network interface device, and encapsulates the network packet on the basis of a public IP address of the remote routing device to generate an alternative packet. |
