The SSDP request is to 239.255.255.250 , but the response is from 192.168.0.1 , which is unanticipated incoming, so the firewall on the PC, UFW, blocks it.

I don't know what happens next, but an hour later it is running properly, and I can see the 2 mapping entries which applications have already opened, and the data they are generating.
I Add port 9999 and it appears to work.

Then thinking the problem might be to do with the Advertising Period, I change that manually from 30 minutes to 1.
This causes the router to reboot.
When it gets going again, the UPnP port mapping table appears empty, although app data is definitely passing through UPnP ports.
Adding port 9999 again fails - remapping error.
So the table really is populated, but it shows as empty in both URC and DG834G's web page.

Attempts to connect to the server on extIP:9999 from remote box fail.

Hi, thank you for the time spent in test UPnP Router Control.

First question: is UPnP feature enabled in your router configuration?

If UPnP is enabled and other programs (like Transmission) can open ports on your router, please run URC from the console in debug mode for give me more informations:

upnp-router-control --debug

I have now switched to a satellite connection and a different router, so
I cannot repeat the tests.

I am sure UPnP was enabled, and some applications could punch through
(Skype?)
