How to enable upnp in opensuse 42 to use qbittorrent

Hello, I an new to openSUSE and just installed v42.1. I usually use qbittorrent as my torrent client and configure it to use upnp and also web-ui to control it from local network. I figured out the way to forward the web-ui port. But i don’t know how to enable upnp in openSUSE. Can some one help me out?
