Your modem exposes a single network interface and runs a web server
within. You can likely configure APN/user/password/PIN and things like
that directly in the built-in web interface of the modem, and get it
connected/disconnected also via HTTP. The HTTP connection is only
between your host and the device (which is where the web server is
running). Some manufacturers are selling these modules as "no driver
needed!", which could make sense in Windows platforms, but we're not
used to these in Linux-based systems. Regarding the NAT-ing, not sure.
Of course you have a private IP address and a public one, but don't
know whether the firmware will end up doing NAT... wouldn't make sense
because it is a 1-to-1 relationship between the IPs, but who knows.
