Reach several home devices from outside through one IP using subdomains — by Daniel on Super User

With one public IP and a domain, run a single nginx reverse proxy that sends device1.example.com, device2.example.com and so on to different internal servers by name. Only that one proxy needs ports forwarded. Anything exposed this way should be secured (HTTPS, authentication) or kept behind a VPN instead.
