       By default, your camera can establish a connection to an external
    computer as easily as you can do it with a web browser.  For an
    Internet-of-Junk device like your camera, that's typically some
    rent-a-computer in "the cloud".  For example: https://aws.amazon.com/

       And when your camera "phoned home", it did that, too.

       It's the router part, not the modem part, but...

     

       Visit http://netgear.com/support , put in your model number, and look
    for Documentation.  Get the User Manual (at least).  Read.  Look for
    "Address Reservation" and "Block Services".


       Fix the LAN IP address of the camera (Address Reservation).  Then use
    ADVANCED > Security > Block Services to block all protocols and ports
    for that address.

     

       Note that doing this can stop some features from working (remote
    access to the camera, for example).
