Configure DNS Servers

For supported software information, click here.

You can configure Domain Name System (DNS) servers for individual routing instances. For any DNS configuration, you must configure either source interface or source network. You can configure explicit DNS servers when you want to avoid non-routable interfaces (paired TVIs) or when a DNS server is not present in a VPN and the DNS request must traverse a tunnel.

To configure a DNS server:

1. In Director view:
   1. Select the Configuration tab in the top menu bar.
   2. Select Templates > Device Templates in the horizontal menu bar.
   3. Select an organization in the left navigation bar.
   4. Select a device from the main panel. The view changes to Appliance view.
2. Select the Configuration tab in the top menu bar.
3. Select Others > System > Domain Name Servers in the left menu bar. The main pane displays the configured DNS servers.
   
   
4. Click theAdd icon. In the Add Name Servers popup window, enter information for the following fields.
