Abstract

To facilitate managing a VPN including sites where a global address can be changed.SOLUTION: A router includes: a terminal information acquisition unit that obtains a global address of a terminal under control of the router; a network information notification unit that notifies a global address of the router and the global address of the terminal under control of the router to a management server; a network information acquisition unit that obtains, from the management server, network information including a global address of another router and a global address of a terminal under control of the other router; and a VPN construction unit that constructs a VPN with the other router by using the network information; and a routing unit that performs VPN processing and routing for communication by the terminal under control of the router according to the network information.SELECTED DRAWING: Figure 3
