I managed to connect my Raspberry Pi to the Internet (accessing web pages, ssh to a known server,...). Everything works fine.
Now what I would like to do is connecting into the device from a remote network.
The external IP I get is dynamic, but I simply read it using "whatismyip.com" accessed from the raspberry Pi, say it is 220.127.116.11 (this is just an example, not a real IP!)
However when I try:
ssh -l pi 18.104.22.168
from a computer connected to the Internet on a remote network, the connection is not working (timing out). It is as if all outgoing connections were allowed and all incoming connections disabled.
Is this a restriction from my provider (Orange?), a limitation of the Huawei dongle, or am I missing something?
Eventually I would like to use no-ip.com to connect to the Raspberry but before that I need the test above to work.
