Hi There,

What is the DNS registration best practices when Always On VPN client uses both User and device tunnel? is it recommended for client register both device tunnel and user tunnel IPs with DNS server? is it ok fine to register only device tunnel IP with DNS as it is required for manage-out? Have two IP addresses registerd in DNs will it cause name resolution issues.

    Hi ,

    Welcome to our new Microsoft Q&A Platform.

    >>is it recommended for client register both device tunnel and user tunnel IPs with DNS server? is it ok fine to register only device tunnel IP with DNS as it is required for manage-out?

    Best practice is to define the RegisterDNS element only on the device tunnel if you are using it.

    Please refer the following link for more information:

    The different IP will not cause resolution issues.

    Best Regards,
