I have an issue with SSH as it does not work from outside of the home network. I performed a test using the same machine and Putty.
In my home network I connected through local IP address and port 22. I tried to reach the device remotely using public IP and some high port (above 2000), which was assigned to me by ISP and linked to my device and its port 22. It seems like the device is reachable, but for some reason it refuses to establish connection. I use the same user, which is in ssh group. I have also allowed root user login, but it did not help.
Do you know what might be the solution?
