A method and system for forwarding data between network devices is provided. A routing device receives, identifies and forwards data to a network device coupled to a private network. The routing device may make a determination of how to forward the data, for example by determining which of several delivery mechanisms to use. The network device may be also associated with a public network via a public network device identifier (PNDI). The PNDI may include a public IP address of the routing device, a public first port number such as a destination port number, and optionally a public second port number such as a source port number, the combination of public IP address and public port number(s) being unique to the network device.
