I have been trying for a couple of days to get a connection to my desktop, from a laptop, via the internet.
The desktop is my home PC, and has a BT router. The laptop is connected to the internet via my mobile, using the phone as a hotspot.
First off, the NoMachine installation on the Desktop shows the IP address as: nx://192.168.1.250, and nx://188.8.131.52:29964, BUT, using WhatIsMyIP.com the reported address is: Your Local IP is: 192.168.1.250, and Your IPv4 is: 184.108.40.206
However, nothing works as per the NoMachine instructions for connecting over the internet.
