The following are the steps involved and the recommended settings to configure the DNS Virtual Service:

  1. In the main menu of the LoadMaster Web User Interface (WUI), go to Virtual Services > Add New.

  2. Type a valid Virtual Address.
  3. Select the DNS template from the Use Template drop-down list.
  4. Click Add this Virtual Service.

If adding a DNS Virtual Service on a network not associated with the interface containing the LoadMaster's global default gateway, a Virtual Service Default Gateway is required. It is not possible to set a default gateway on a UDP Virtual Service. To set the default gateway for a UDP Virtual Service, use this workaround:

  1. Create a TCP Virtual Service with the same IP address (the port is irrelevant). Do not add any Real Servers.
  2. Set the Default Gateway for that Virtual Service. It will also affect the UDP Virtual Service (that is, the required one).
Note: Default gateways only work on IP addresses, so having two Virtual Services with the same IP address and different default gateways does not work.
