gateway for VM

Question

Hi,

I now how to setup the VMs of an hyper-v host and they will have internet connection.

But today I rent a dedicated host at a datacenter, that has 2 NICs and only one of the NICs get public IP from the DHCP of the datacenter. I did install the Win2019 and setup the Hyper, but I have no idea on how to allow VMs on this host have internet access.

I did create a external VM switch with the nic that has public IP and connect a single VM to this switch. I want to give IP 10.0.10.0/24 to the VM but I have no idea what to use as GW for this VM.

Any suggestion on how to allow this VM to have internet access?

Thanks

Answer 1

Hi ,

Based on my understanding, you want to manually assign private IP to the VM and allow this VM to have internet access. Is that right? Please feel free to let me know if I have any misunderstanding.

If yes, you can deploy a NAT Virtual Switch which allows virtual machines to have an internal network and have internet access. Each VM is connected to an internal virtual switch and will use WinNAT to connect to a private IP subnet. WinNAT gives a machine access to network resources using the host computer's IP address.

As the picture below:

For more details about how to using a NAT Virtual Switch with Hyper-V, you could refer to the following article:

Answer 2

@Candy Luo Thanks for your reply,
your suggestion has solve my problem with having internet access on the VMs.
But now I come acrosse this issue
We have multiple webservers on different VMs on this hyper-v host, how can we allow access to the webservers?
normally we can use some kind of nat device or utm that is in front of the hyper-v host but right now we have only a simple firewall that allow us to open a port to the hyper-v host.
How can we send the web requests to the the webservers on the VMs?
Any suggestions?
Thanks
