Abstract
Transmission of an open systems interconnection (osi) network protocol packet to at least one routing device between a computing device and a public network is repeated to learn a number of routing devices and an internet protocol (ip) address of each at least one routing device between a computing device and a public network. A routing device discovery protocol request is sent to each at least one routing device. A routing device discovery protocol response is received. A port forwarding instruction is sent to each at least one routing device based upon the routing device discovery protocol response to allow incoming content from the public network.
