Hi.

I have set up 4grouter and some cameras behind that and also have other location where is dahua nvr and of course, internet connection. I cant add port forwarded cameras to dahua nvr - how i can add those? Nvr cant connect while i try to add manyally those ip and ports..

Site 1:
I have dahua nvr4432 there. Local dahua cameras and all working fine.

Site 2:
Network router where i have done port forward to 1 dahua ip camera, ports 37777 and 554. I have network connection with public and static ip address.

Question:
How i can add Site 2' s camera to Site 1 NVR? Manual add -> what settings needed. I have checked ports are open (canyouseeme.org) but i cant success eith nvr manuall add fields..

Any idea how i can fix this
 
I'll skip the part about port forwarding being a bad idea, are you saying you're trying to reach cameras on a network router over the Interwebs at a different location and add them to the NVR at location #1?
So the IP of this camera you want to add would be a publicly reachable WAN address?
 
Yes. Just like you said, publicly reachable. I know better idea would be to connect routers with openvpn/similar solution but at the moment i try to add cameras with port forward
 
I have tried same kind of settings.
There is 2 different cameras behind one 4g-router, so i have forwarded ports 10000 for cam 1 37777 port and 10001 for cam 2 37777 port. Not working. Well, maybe i try to check is there any new firmwares available for the routers because your solution is clear to me but not working here mate.
 
It may be a matter of the rules on the router. On my Asus routers I set up 2 rules: port 80 and port 37777 to port forward to the camera IP
 
I just discovered something VERY odd.

I went back into that router (via OpenVPN) removed the port forwarding , turned OFF “enable port forwarding” and refreshed the router and verified the changes took. I cannot reach the remote camera via browser or SmartPSS as expected.

HOWEVER, I can still reach it via the NVR, watch live video, and it still shows connected on the NVR??????? WTF?
 
OK I rebooted the router and it went away/disconnected.

Hmmm I guess "Refesh" isnt enough
