Windows 10 Hyper-V "Default Switch" question

Question

Hi,

The VMs on Windows 10 Hyper-V set to use the default switch on Windows 10 Hyper-V receive dynamic IP addresses. There is no setting to set it to static IPs.

To get around this issue I have created an internal switch and set up a NAT to provide VMs external access to the wider LAN and everything works but came across a Hyper-V on Windows 2016 article that stated that on Windows only a single NAT is supported. Two questions:

1- Is is still the case on Windows 10?

2- When I issue "Get-NetNat" command, only my custom NAT shows up. I don't see the one which I assumed to be behind the "default switch" showing up. What am I missing? Or is my assumption incorrect?

Thanks!

Answer 1

I received confirmation from the product team that support for multi NATs have been added to Hyper-V. Thanks everyone.

Answer 2

Hi,

Multiple NAT networks are not supported on windows 10 too.

Besides, as I learned, we need to use an Internal Virtual switch to create NAT with powershell command. So the NAT may not behind the default virtual switch.

Please refer to the following article for detailed information:

Thanks for your time!
Best Regards,
Anne

Hi @Xiaowei He ,

Thank you for response, as stated I have already created a switch and bound it to a new custom switch to allow static IPs. The question was now there seem to be three NATS running on my machine, one behind the default switch, one behind my custom switch, and one behind WSL switch and was wondering how is that possible if a single switch is still the limit.

Anyway on twitter I connected a resource who used to be on the Hyper-V team and she has forwarded my question to an engineer on the product team. I'll post his response here once he responds. Thanks.
