Most of the time we need multiple networks in our LAB to simulate cross site features. Today I will explain, How can you do this with Windows Server, VM Workstation with minimal effort.

There could be n number of scenario when this could be helpful but I would try to emphasis that you shouldn’t use this in your production infrastructure.

I will explain how to enable network communication between two networks (192.168.20.128/24 & 192.168.21.128/24). We will use VM WorkStation and LAN Routing feature of Windows Servers 2012. You can use any other hypervisor like virtual box as well.

My Infrastructure :-

  • VM Workstation 15.0 installed on Windows 10.
  • DC – 192.168.20.128
  • Misc – 192.168.20.11
  • Client – 192.168.21.129

Initially, if we ping 192.168.20.128 from 192.168.21.129 then it will throw request time out.

  • Add a host Only network in VM Workstation, Here it is VMnet2 with subnet IP 192.168.21.0

LAN

  • Now Navigate to server named MISC, this will be our router server.
    • Add VMNet2 network on this server under vm workstation.vnet2.JPG
    • Login using Administrator account and install ‘Remote and Routing Access’ feature.remoteaccess.JPG
    • Select ‘LAN Routing’ It will automaticlaly select ‘Direct Access and VPN’LANRouting.JPG
    • Finish Installation.
    • Now configure by clicking ‘Routing and Remote Access’.remote.png
    • FYI, At this point we have two LAN on MISC machine. Here is the ipconfig output from MISC machine.
    • configure2.png
    • Click on ‘Configure and Enable Routing and Remote Access’configure1.png
    •  Click on ‘Custom Configuration’.21.JPG
    • Click on ‘LAN Routing’LT.JPG
    • Now start the service.start.JPG
    • Now, you will see both LAN.Done.JPG
    • You would have to use hightlited ip address in gateway field of the servers you build in the same network, it will allow cross network communication.
  • Here is the ping result from both networks, you can notice ipconfig result of the local server and ping result of the other server.
    • Ping from 192.168.20.128 to 192.168.21.1281way.JPG
    • Ping from 192.168.21.129 to 192.168.20.1282way.JPG

We have successfully configured the LAN routing, now you can test your cross site communications and deploy servers in both networks.

Thank you for reading.
