I have to monitor an isolated area and this came up to the following setup:
- zte mf823 4G dongle
- IP camera using P2P / DDNS with
So the IP camera is connected to RPI through Ethernet cable, so I'm trying to link this connection to internet via my 4G dongle (guess what, I have no idea how I can do this). After few searches I found out the following site: https://esther.codes/post-pi_router_story/ which is great, it has few common points, but it still don't solve my problem.
What I understand is that I have to install / configure a dhcp server on my rpi, then I have the share the internet between USB dongle and my IP camera. So lets say I'll do that, then is my camera reachable via DDNS or P2P from an external network? that is possible using a standard wifi/ lan router if there is activated the uPnP feature or configuring the Port Forwarding for my camera. How can I do this on RPI ?
If is somebody who did something similar, I'll appreciate any guidance and information.
Thanks in advance,
