I've read where a reverse proxy may be what I need to accomplish the following goal.
My router forwards 443 traffic to the Virtualmin server (192.168.0.100).
I have a Raspberry Pi3 on another device that is also listening for traffic on 443.
If HTTPS://www.whatever.com points to my main server, can HTTPS://otherdevice.whatever.com be re-routed to the Raspberry Pi3?
If so, how does one accomplish this in Virtualmin?
