Abstract
A method of enabling an electronic privately addressable source to be publicly addressable starts at a receiver where an electronic message is received. It is communicated from a sender with a private address outside a subnet of the receiver through a translator. The translator retrieves a lease to at least one of a public address or a port from a lease manager, translates the private address and the private port into a public address and a public port and communicates identifying data such as the public address and the public port to the receiver. If a response is communicated to the private sender, the response may be communicated to the private sender through the network. The public address and the public port on the message may be translated to the private address and the port of the private sender and the private address and the private port may be used to properly route the response to the private sender.
