When the LoadMaster is deployed in a two-armed configuration, we recommend enabling Subnet Originating Requests. When this option is enabled, the LoadMaster will use its local IP address, instead of the IP address of the Virtual Service, when communicating to the Real Servers.

Subnet Originating Requests can be enabled on a per-Virtual Service or a global basis.

Note: It is recommended that the Subnet Originating Requests option is enabled on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

  1. In the main menu of the LoadMaster WUI, select System Configuration > Miscellaneous Options > Network Options.

  2. Select the Subnet Originating Requests check box.
