Abstract
A system and machine-implemented method for communicating with a client device. A server receives a first request by a client device via a first communication protocol, wherein the first request establishes a NAT binding which defines a communication path from a server to the client device. The server sends a response to the received first request via the first communication protocol, wherein the response is directed to the client device based on the NAT binding. The server determines that the response is unsuccessful in reaching the client device. In response to the determination, the server transmits a communication to the client device via a second communication protocol which is different than the first communication protocol, wherein the communication instructs the client device to re-establish the NAT binding.
