32660-untitled-picture.pngHi Team,

How to change the connection type of default switch on Hyper-v?
last time, I opened Hyper-v, all virtual machines could access to physical network and go through Google.com.
But this time, I opened one of my virtual machines, I found that

  1. Network shows that "Internet Access", but I could not visit google or any other websites.
  2. Network shows "domain network"
  3. After I check the switch of Hyper-v, the connection has been changed into "Internal". I could make sure that it was "External" last time.
  4. My PC runs Hyper-v with domain joint and VPN enabled.

How could I make the virtual machines on Hyper-v could access the Internet again?

Thank you

    Hi @knight xu ,

    The Hyper-V default switch is in internal mode and automatically uses NAT, the default switch cannot be modified.

    You could consider creating an External virtual switch instead, and connect all your Hyper-V virtual machines to the External virtual switch.

    You can follow the step-by-step guide from the official documentation here:

    The simplest method is to delete the internal vSwitch, create a new external vSwitch and connect the guests to new external switch.

    I see you just edited your original post. The "internal" you asked about is the default switch which you cannot edit. The simplest method is create a new external vSwitch and connect the guests to new external switch.

    Hi，

    Windows 10 default virtual switch is unable to edit, and the settings in your screenshot if normal:

    If you want to make the VMs connect to Internet, we may create an external virtual switch on the Hyper V host, then connect the VMs to the external virtual switch:

    Thanks for your time!

    Check the Setting here on guest

    If the Network Adapter is missing you can add a new one.
