Setting up my domain on NAS behind Sophos XG

Question

Hello 
 I have my own domain, let's call it www.mydomain.com, I would like the user who enters in a browser ending up on my private NAS which is behind my newly setup Sophos XG. I know that I have to edit the DNS at the domain registrar to my private IP address. Here is where my questions start. 
 Unsing Sophos UTM I had to give is a fully qualified domain name. I used to call it "mydomain.com", I then entered a physical and a virtual webserver in UTM, this worked fine. 
 - In Sophos XG I haven't found the setting where I have to enter the name, can you tell me where it is? 
 - Am I supposed to call my firewall for example utm.mydomain.com or can I just use mydomain.com? 
 - Where do I have to set up the www? So that all www.mydomain.com end at the NAS? 
 - At the registrat of my domain, do I enter www.mydomain.com or utm.mydomain.com? 
 Thank you

Roger, 
 in XG you have to use Business Application Rule and choose Http Based policy. 
 Follow this guide (it is used to publish Non-HTTP): https://community.sophos.com/kb/en-US/122976 
 On your registrant, register www.mydomain.com

No. Use the same HTTP template and turn on HTTPS. Create the Web server under Protected Application Servers and here you can choose if create the HTTP or HTTPS Server. 
 So you can have HTTPS on WAN (published by XG) and have HTTP server or have both HTTPS (both XG and Web Server). Make sure you upload the HTTPS certificate on the XG.
