I tryied UPnP experience and I'm glad to share it with you.
First, I'm sorry Al, that I said that UPnP service does not work with 1.9.2.7-10.7 firmware. It work.
First we have to assure that UPnP service is installed and is working under Windows:

Second there are only few utilities to command router port forwarding from Windows. I tried about 5 of them an no one work except of this:

...but the download link from the above site is broken
, so I found it and put it here in attach.
I hope you are satisfied with this!
