If it's only your NVR you want to access , have a look at Rmot3.IT .Hi
Bumping this thread as I took out the 5G product.
How would setting up a VPS assist with CGNAT / Double NAT and has anyone tried it.
I am looking into a Blueiris/ngrok setup for my hikvision NVR.
but interested to know how one will address something like online gaming issues that are picky with NAT types etc.
I did a tracert and see it hops through two private addresses (10.x.x.x) before going outside. I'm by no means a network expert so don't know what this means.
If you have a spare\old machine sitting at home doing nothing or a RPI , then that might help you out with a few things ,
VPS i'm also still busy looking at , setting up a vpn going out of your network is the easy bit , At the moment allowing traffic in is a bit harder because of the CGNAT . There are a few options but so far most of them require you to have a machine \ VM always online on your internal network and use that as a gateway\reverse proxy.
I have not been able to setup a VPN server on primary router as it picks up the double nat straight off the bat .
As you would have seen with the 2 X 10.x.x.x addresses . It also doesn't work if you allow the IP to be passed through or placing your router in the DMZ .
