Programmatically Open External Ports with UPNP

Описание

Allow External Access to WebServer in a Local Area Network with Upnp

Upnp is a technology that allows external traffic to connect to an internal server. It is extremely useful for cases where the server is behind a router and is listening on private IP address such as 192.168.1.1 or 10.0.0.1 or 172 which are not addressable in the Internet. Use cases are peer to peer and webRTC

In this video I’ll show how we a client in a local area network can ask the routers that support upnp to open an external port.
