The DNS Settings can be used to configure conditional DNS forwarding through a private DNS service and to specify a public DNS service to be used for querying purpose.

To configure the DNS settings for a Profile:

  1. Log in to VMware SD-WAN Orchestrator, and then go to Configure > Profiles.
  2. Either click the Device icon next to the profile for which you want to configure the DNS settings, or click the link to the Profile, and then go to the Device tab.
  3. Configure the following settings in the DNS Settings area:

    • Conditional DNS Forwarding – Select a private DNS service from the drop-down list to forward the DNS requests related to the domain name. You can also choose the New Private DNS Service to create a new private DNS service.
    • Public DNS – Select a public DNS service from the drop-down list to be used for querying the domain names. You can also choose the New DNS Service to create a new public DNS service.

    For more information on creating new DNS service, see Configure DNS Services.

  4. Click Save Changes.
Note: The global segment configuration for DNS applies to all the customer-created segments.

At the Edge-level, you can choose to override the DNS Settings configured for the Profile.

  1. Log in to VMware SD-WAN Orchestrator, and then go to Configure > Edges.
  2. Either click the Device icon next to the Edge for which you want to override the DNS settings, or click the link to the Edge, and then go to the Device tab.
  3. In the DNS Settings area, select the Enable Edge Override check box, and then expand the area.
  4. From the Conditional DNS Forwarding and Public DNS drop-down list, select the required private or public DNS service if you choose to override the DNS service at the Edge-level.
  5. From the Source Interface drop-down list, select an Edge interface that is configured for the segment. This interface will be the source IP for the DNS service.
    Note:

    When the Edge transmits the traffic, the packet header will have the IP address of the selected source interface, whereas the packets can be sent through any interface based on the destination route.

  6. Click Save Changes.
