How do I access my Raspberry Pi from anywhere?
If your tunnel status is online then you can open your raspberry pi terminal using noVNC on a browser from anywhere. Open a browser in any computer or mobile phone that is connected to internet and type the address marked in the image onto the browser's address bar.
Can I RDP to Raspberry Pi?
With RDP, you can log in to a Raspberry Pi box from another computer running Windows, Linux or macOS, and create a real desktop session the same as if you had logged in to a local computer. The Pi and the client machine have to be connected to the same network or to the Internet.
