Virtual switches and routing in hyper-v

Question

Hi, so currently everything works within my environment. I can get to any external address and the 10.12.60.0 network can communicate amongs itself.
It can also reach anything on the host network 10.0.0.0/24.

The problem is inbound traffic. I've attached a very rudimentary diagram of my current setup. Since this has DHCP I have set this up as internal, but obviously that's a problem. Is there any way to add external nat'ing so I can NAT my host network and still operate with DHCP on this internal network?
Or is it recommended to use external and staticly set each of these servers on their own subnet without DHCP so I can have inbound connection?
Since they're all domain-joined in a test lab I'd love to use dhcp on a dc on the 10.0.0.0 network but I'm open for anything as long as the networks remain logically separated, but can have inbound traffic to this lab.

I've spent a ton of time on this, including msdocs and guides, but can't seem to find a way to do this, so any help would be greatly appreciated.

The simplest solution may be to use an external vSwitch, otherwise you may need a dedicated virtual machine to act as a router between the internal and external networks.
