isolate VM network from work network and in the same time gain internet access to VM using Hyper-V

Question

Hi

I want to isolate my VM network from my work network and in the same time gain internet access to VM, I followed the video tutorial and it did not work, the link: https://www.youtube.com/watch?v=30X0oOwCruE

in the video, he is using DHCP to configure IPs of his VMs, in my situation I did not enable Windows server DHCP, I put the IPs manually.

Details as follow:

Windows Server (DC)

• Internal Switch:
  • IP: 10.10.10.1
  • SM: 255.255.255.0
  • DG: 10.10.10.20
  • DNS: 10.10.10.1

Windows Server (Router)

• Internal Switch:
  • IP: 10.10.10.20
  • SM :255.255.255.0
  • DG:NON
  • DNS10.10.10.1 (DC IP)
• External Switch:
  • The IPs is from the work DHCP

I have enabled the NAT on the router, I selected NAT routing then selected the External Switch, and the internet is working on Router Server but unfortunately, the DC did not receive internet.

I saw some other videos where they assign Google DNS to the server/client and yet still did not work, however, I really want to do it without need to assign google DNS as I want full isolate as shown in tutorial video.

Kind Regards

Answer 1

Hello!

I see you pointing both your internal network interfaces to the DC as a DNS server. Have you configured the DNS for the domain controller? He does not mention it in the video to my knowledge.

Another thing you could test is, can you ping 8.8.8.8 from the DC? If so then its definitely DNS related.

The setup should work as mention in the video, but make sure you configure your DC:s DNS if you have not done so :)

Hi Timmy

Thank yo for your support.

in the video at 11:48 in the Router server he used DC IP in the DNS (in the video 11:48) as in the picture below:

The configuration he did in the DC:

I will reconfigure everything again, I will update you.

Hello,

 

Thank you for posting in Q&A forum.

I can understand that you want to seperate this VM from your work environment. However, in this business scenario, you will need a specific DNS Server to resolve the DNS query from DC. If you doesn't want to use google DNS Server 8.8.8.8, you can bring in another private DNS server to answer DNS query. Otherwise, it will not be able to get a proper connection to the internet.

 

You can try to configure a DNS Server for DC and compare the nslookup outcome before/after the change to doulbe verify this point.
