[p2p-hackers] Getting started with UPnP on Win32

[David Barrett]

Can you recommend a good resource for getting started with Universal 
Plug-n-Play on Win32 for NAT traversal purposes?

I see the various UPnP APIs (Control Point, Device Host, etc.) in the 
MSDN docs, but I don't see specific mention of how to apply them to NAT 
configuration.  Rather, they seem to give an overall approach for 
configuring an arbitrary UPnP device, with details on specific devices 
left as "an exercise to the reader".

Can you give me the 30-second overview of COM objects and function calls 
I need to use?  Or can you refer me to a decent overview of the subject? 
   If nothing else, do you know of some sample code that shows 
configuring a NAT device to allow incoming data?

Thanks!
