When you have two internal IP Addresses that need to receive 443 traffic...

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 (

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?
