RPi3 is connected to internet via 3G dongle.
wwan0 interface IP is in public range, is accessible from outside and hasn't changed since I got the SIM. So far so good, right?
What worries me, is that a probably NAT-ed IP is sent to noip, not the interface one, making the site served by RPi inaccessible, unless the IP is known. Is there a way to send the "correct",
wwan0 interface IP to noip?
Second worry is that when RPi will be moved off-site (to measure indoor temp), the dongle will use a different mobile mast and probably the IP of the
wwan0 iface will change. My fear is that I will have to do a custom script to notify noip about the interface IP when IP changes or some sort of other notification.
Any feedback is appreciated!
