Okay I won't turn on uPNP.No, don't enable uPNP, that's so the NVR can set up its own port forwarding in your router, not good practice.
Have you tried a couple of NVR's that show up in the drop down menu after you select the make of "Swann"?
I will try that tonight. Forgot to leave the BlueIRIS desktop and switch ON so i can remote in and play with it at work haha
