Domain Name System (DNS) is used to configure conditional DNS forwarding through a private DNS service and to specify a public DNS service to be used for querying purpose.

The DNS Service can be used for a public DNS service or a private DNS service provided by your company. A Primary Server and Backup Server can be specified. The public DNS service is preconfigured to use Google and Open DNS servers.

To configure DNS settings with the New Orchestrator UI:

  1. In the Enterprise portal, click the Open New Orchestrator UI option available at the top of the Window.
  2. Click Launch New Orchestrator UI in the pop-up window.
  3. The UI opens in a new tab displaying the monitoring and configuring options.

In the new Orchestrator UI, click the Configure tab.
