Building a CM Lab – Gateway VM [2]

Series Post 2, Setting up the Gateway Virtual Machine, a virtual router

If we have a lab and we want to keep it separate from rest of our environment, we need a gateway. You can do this with a linux VM, another physical router, or several other options. For our lab, we decided to use Microsoft Windows Server to be our gateway. After setting this up, looking back, it would have been easier to setup the DC first, so I’d recommend doing that, then setting this up.

  • Gateway Server
  •  Name:
  •  LAN 1: DHCP (External Network)
  •  LAN 2: Static IP (Internal Lab Network)
  •  Windows Roles: RAS [MS Docs]

At this point, I’ve installed Windows Server 2019, set the Name, the IP Address, ran MS Updates and installed the RAS Role by running a powershell commands: 

Install-WindowsFeature DirectAccess-VPN -IncludeManagementTools

Install-WindowsFeature Routing

Once that finishes, you can go ahead and setup the “Router” feature.

Server Manager Remote Access
With Remote Access Highlighted, click “More” which will then launch the details and you can launch the wizard
Configure Remote access
Deploy VPN Only Option
Routing and Remote access
Routing and Remote Access will Open, right click on the computer name (GATEWAY) and choose “Configure and Enable Routing and Remote Access”
Routing and Remote Access Server Server setup Wizard
Remte and Routing Access server Setup Wizard
Choose the “NAT” Option
Routing and Remote Access Server setup Wizard
Pick the External NIC for your public interface
Routing and remote Access server setup wizard
I’m choosing “Setup later” because these services will be on my DC
Routing and Remote Access Server Setup Wizard
DC Virtual MAchine Connection
Nearly instantly my DC gained internet access by being able to use the router function on the gateway PC.

This is probably the easiest server you’ll be setting up. If you run into any issue, don’t worry, go ahead and setup the DC. Once you setup the DC, you need to remember to come back to the GATEWAY and join it to the domain.
