AutoPortForward discovers gateway devices (ex: routers) and attempts to forward the port specified on a one of the devices. AutoPortForward will remove the port forward on disable, and add it again on enable. This is possible by sending a UPNP TCP request to forward a port to the gateway device, if it has UPNP, it will accept this request and forward the port specified in the server.properties. It also tells you your external ip. |
