Encrypted communications are performed between private networks over a wide-area network (e.g., the Internet) by way of routers, each of which includes a management table for storing entries including identifiers and control parameters. Uplink control connections are established between routers so as to mutually communicate and update stored contents of management tables therebetween. Updated stored contents of management tables are subjected to publication to other routers. Alternatively, stored contents of management tables are periodically subjected to publication to other routers. Thus, it is possible for operations managers to reduce manual operations for setting up control parameters in management tables of routers.
