Network Problems with NetNAT instead of ICS RRS feed

  • Question

  • Hi everybody

    I'm experiencing network problems in virtual machines that are connected to a "NetNat" network

        The Hyper-V host is Windows 10 pro, 1809 [Version 10.0.18363.836]).

        Multipe guest OS's in my virtual machines - ALL are affected

        Internal Virtual Switch created and NAT network setup using New-NetNAT, as documented

    The following types of network traffic/services DO work:

        Guest OS's can ping each other and the vNIC on the HOST

        The Host can ping each Guest OS

        Traffic between Guest OS's is 100% OK

        Guest OS's can ping remote websites such as google dns and microsoft.com by IP and by FQDN

        Guest OS's can browse the web (both http and https) and download files

    What DOESN'T Work (oddly enough, all Microsoft related)

        Evaluation editions of Windows cannot activate

        Windows Update doesn't work

        WSUS Synchronization with Microsoft Update doesn't work

    The same issues occur if I connect the virtual machines to the 'Default' virtual switch instead of the one I created.

    I should point out that If I disable NetNAT and share internet access with the internal virtual switch using the traditional Internet Connection Sharing (ICS) method, everything works 100%

    Any Help would be greatly appreciated

  • Hi ,

    It seems your question is more related with Hyper-V network which our forum doesn't focus on, I would suggest you have this asked in Windows 10 Virtualization for better answers.

    Here is the link:
