I'm trying to switch my Surveillance NVR from a wired connection through a D-Link Powerline AV2 2000 to now be wired into a TP-Link AC1200 WiFi Extender RE315.  On the powerline kit, I had no issues connecting to the NVR either within network or externally.  However now with the Extender, I can only get a connection while within the same network.  Switching my phone from wifi to phone service I am unable to get a connection.  Hooking up my laptop to the ethernet cable shows the extender does provide a valid connection to the internet.  So I figured it was a port forwarding issue, but I opened all possible ports that the sw uses.  NVR software shows it is configured for only 85 and 9000, but manufacturer (Swann) says all of the below are possible, so I opened all of them to the NVR client. The forwarding doesn't help anything.  I don't know what else to try or where to look.  I looked in the System Log hoping it would show some kind of rejection message when attempting to open the cameras, but nothing ever comes up.
