Dynamically allowing traffic flow through a firewall to allow an application server device to perform mobile-terminated communications

摘要

A network device may receive, a flow control request for a first device that is registered for an internet protocol (IP) pinhole service. The flow control request may include a device identifier associated with the first device and a private IP address. The network device may identify at least one of IP address information, port information, and pinhole rules. The network device may provide, to another network device, a flow control response that includes at least one of the IP address information, the port information, and the pinhole rules. The flow control response may cause the other network device to allow traffic flow through the firewall using at least one of the IP address information and the port information. The network device may provide a public IP address and a port identifier to a second device, allowing the second device to provide traffic to the first device.
