Currently working through the tutorial here: http://www.youtube.com/watch?v=cTjy-L8C6WM

I have been extremely careful to do everything exactly as the tutorial does. However, when I run the server I get:
  1. "UPnP: unable to open UDP port"

Here is the full screenshot:



Any thoughts on what might be going wrong? Thanks!

It's harmless. It means your UPnP is not functional. Apple Airport Extreme routers have a different way of opening ports (not through UPnP), and I haven't added support for that (yet).

A lot of routers have inconsistent UPnP behaviour. My WD N750 sometimes opens them and sometimes doesn't, it seems to be on its own whims. Even beyond the Airports, I don't know if UPnP can be widely relied on.

Thankfully opening the ports manually works just fine. The UPnP messages can still show as failed, but traffic gets through regardless once ports are opened (one way or another).

All methods of opening ports automatically are unreliable. Sad truth.
