Which IP address is used to look at an IP camera in another network?

I have an IP camera with an IP address of e.g. 192.168.10.1 which is behind a mobile router, which gets a "fixed public IP address", since it is an M2M card and that was so insured for me when booking.

At home I would like to have a live stream from the camera on the monitor. If I plug into the camera or the router with a laptop on site, for example, I can enter the IP address of the camera in the browser and see the picture. What do I have to enter or pay attention to if I want to see the camera from anywhere via the browser?

Think you in your FritzBox? You have to enter a NAT (NetworkAddressTeanslation).

The camera certainly transmits via HTTP port 80. It must be set that if, for example, port 8086 is accessed from outside, this is converted into internal access to the IP of the camera with port 80.

The 8086 is made up.

Then you still need your external IP.

Call line: external IP: 8086, where the IP must be entered resolved.
