Comment 23 for bug 230973

do we *really* need support for more than one upnp implementation?
regarding passive, isn't the external ip fetched from upnp? without that, active mode is useless...in the long run, a browser style infobar appearing would probably be the nicest solution...falling back to passive is maybe not desirable but still better than not working at all (and it's closer to the truth - when there's no upnp setup, we're effectively in passive mode)
