NVR RLN8-410

Getting a connection failure in both the app and the desktop client. Both recognize the NVR after taking some time to do that, but the app is getting "Connection failed." on my cameras now, continually refreshing with no channel image showing up.

I have an airport extreme 802.11n 5th gen, reserved a DHCP IP address for the NVR, unclear what my port mapping should be. Enter all 9000?:

Service: Custom
Pubc TCP: ?
Public UDP: ?
Private IP: (above refernced IP)
