Abstract
A domain based tunneling scheme allows a Network Management System (NMS) to manage devices in a private network operating behind a NAT boundary. A device in the private network provides the NMS with information including a public NAT IP address, a private device IP address, and a unique device identifier. The NMS uses the public NAT IP address to set up and maintain a tunnel to the private network. The NMS stores the NAT information and a tunnel identifier in a table entry associated with the device. The NMS then uses the tunnel and the contents of the table entry to conduct management operations with the device operating in the private network.
