[AutoPortForward]有什么作用?
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 forwarda 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.
