Does anyone know what network ports need to be opened for the Prism phone app to work with the Prism DVR? I've set up my own router and everything works fine inside my home network but once I switch to LTE the app gets stuck at "Updating DVR Data". I can then enable DMZ for the Prism STB on my router and it works again, so I just need help narrowing down the ports I need to configure to forward on my router.
