This Extension redirects "Click N Load" requests from localhost:9666/127.0.0.1:9666 to an IP or host entered in the Plugins Options. On this address usually jDownloader is listening for incoming Click'n'Load requests. But if you use a server based downloader like pyload you have to setup a port forwarding every time. On the Options page you can define a value to be set as new Hostname or IP. With this Extension you don't need to setup an SSH Port Forward to payload anymore.
