Suggested change:
NetPeer.Internal.cs

Change line 411
From: if (resp.Contains("upnp:rootdevice"))
To: if (resp.Contains("UPnP/1.0"))
Or: if (resp.Contains("upnp:rootdevice") || resp.Contains("UPnP/1.0"))
which will cause it to get trapped/return before the warning is issued.

I'm honestly not sure what this service provides, but it doesn't appear to do 
any port forwarding, so I suspect it is something that can be thrown away, 
however, it doesn't match on the upnp:routdevice string as other UPnP services 
do, however, it appears all should contain UPnP/1.0 in the SERVER header.  I'm 
not sure if additional handling would be required.
