Abstract
A node device provides secure communication services over a data network, such as the Internet or another public or private packet switched network, to multiple computers that are coupled through the node device and multiple other node devices. The node device includes a network communication interface for coupling the node device to the data network. The node device includes a data storage containing cryptographic information including information that is unique to the node device. The node device also includes a tunneling communication service coupled to the network interface configured to maintaining an encrypted communication tunnel with each of multiple other node devices using the cryptographic information. For example, the encrypted communication tunnels are implemented using the IPsec or PPTP protocols. The node device includes a routing database for holding routing data and a router coupled to the tunneling communication service and to the routing database. The router can pass communication from one communication tunnel to another. A centralized server can be used to control the node devices in a centralized manner, thereby reducing or eliminating on-site administration of…
