FurryNutz,
Wanted to thank you for posting at the beginning of this thread about setting the cameras to use uPnP and uPnP port forwarding. I have four 934L cameras and three of them started to lose their video feed for unknown reasons. After trying everything that I knew of to try and get them working again I finally came across this thread and your comments. Set the uPnP checkboxes on all camera and viola!! - they all started working again.
Just wanted to say thanks . . .
