Abstract
The present invention relates to a method and system for determining devices connected to a private network through a gateway. A Network Management System (NMS) through the use of inquiries and Port Address Translation (PAT) commands is able to determine the topology of the network of devices within a private network and thus communicate with them. This is achieved through the use of Port Address Translation (PAT) initiated by the NMS to set a port for each device connected to the gateway.
