I have 10 RPis located at different cities, and I want to remotely and securely access them from the office, control them, update the contents, etc.
As I've searched so far, there are several ways to do so like port forwarding, static IP, etc.
Now I want to know whether it's possible to use my domain/host to do so. I have a domain say www.mydomain.com with a US linux host, and I can create as many subdomains as I like on it.
Is it possible to create subdomains like rpi01.mydomain.com, and use these subdomains to remotely and securely access RPis from anywhere in the world !?
And if yes, how can I do this !?
