So i use real server hardware at home, but since I am not rich, I can largely just afford one and hope to upgrade the disks and memory on just this single unit. Now comes a challenge that I do not have enough experience to figure how to properly implement:

At present, i have a virtualised AD domain in this server. While the server physically comes with two network ports, both are connected to the same switch; I only have one network in my entire home. And naturally only one broadband router out to the Internet. One network port is dedicated to the host machine/parent partition, while the other is for Hyper-V guests. All nodes physical or virtual use

Now, I have interest to simulate a multi-site domain. If I am to set up another domain controller, I'd like to place it in a subnet And this is where I am unsure how to proceed.

I could just assign the second domain controller network adapter to but how can I properly route this, as the default gateway of machines in is - the broadband router. So requests for are just going to shoot out into the Internet with no return. My Linksys router only works as a single subnet. Secondly, machines in the subnet ought to have Internet access just like the original nodes.

It seems I may need an "authoritative" router device that controls both (or more) internal networks, before routing Internet-bound packets to the actual broadband router?

I implement something like this by assigning machines on one virtual subnet & domain to a Hyper-V Internal Only virtual network. Then I use the Server 2008 routing to route between the internal networks and the physical NICs.

I use this for NAT and for rerouting ports on the physical machine to RDP on the VMs - but it sounds like you can just route straight through. It sounds like you can just route through since the IPs will be valid on your external network.

  • so I have to install the RRAS role on the parent Win 2008 partition and make it the router.

  • To use this method, yes.
