Domain name port forwarding question

[wombat833]

My apologies in advance if this has been answered elsewhere.

 

I have a Server 2012 R2 essentials with Anywhere access and have port forwarded my http/https and RDP to my server Mac address to login remotely and access the server and pc's on the network.

 

I now have a domain name and have setup in IIS a simple website and wordpress which I can access remotely as well so all good.

 

What I would like to do is run a vm in hyper v with Nextcloud installed and using my domain access that remotely, but it is on a different IP address and mac address so is there a way to achieve this.  I read up about Round Robin DNS as a possible but can't work it out.  I can access the vm on my local network using the IP address.

 

I hope I have been clear in what I want to achieve and would appreciate any advice.
