What could be the possible cause for me to be able to configure the ppp0 signal from a modem perfectly on my Raspberry Pi, but not being able to access it (the rpi) via VNC via the IP provided by the modem? The IP generated by the modem allows me to access the internet in raspberry and even make a connection via socket. But it's no use for me to access raspberry remotely.
