So, if I want to access my (Raspberry Pi) desktop remotely but from within my LAN, that works just fine via VNC (VNC server integrated into the Raspberry OS, VNC Viewer installed on controlling device). How can I send instructions from a second PC (outside the LAN) to my raspberry VNC server (what they call establishing a cloud conncetionconnection) without having to make the VNC server accessible from the internet? It works, but does it work without forwarding?
And yes, an authentication on the raspberry is needed when establishing a connection, but still, how can this work without forwarding ports?
