I have this physical configuration:
And I'm planning to install IPFire (or similar firewall : pfSense or Sophos UTM) on a virtual machine on the Active Directory Server to control traffic between the internal 192.168.1.0/24 network (including AD Server) and the internet.
What is the appropriate configuration on the AD Server and the VM?
Edit based on Dan's comment: This is planned for a production environment. How about if install both AD and Firewall on virtual machines running on the physical server (Windows Server installed)?
