IP Reuse Domains Mapping Implementation End-to-End Configuration

To enable support for Overlapping IP addresses:

  1. Select Tools > Options > Advanced > Overlapping IPs, and then select Allow Overlapping IP Addresses.
  2. (Optional) When SecureConnector is deployed in your network, perform these configuration steps:
    1. In the Options window, select Linux. Select the SecureConnector tab.
    2. In the Overlapping IP Addresses area:
      • Enable the Specify a local Appliance interface for SecureConnector communication checkbox.
      • In the Local Appliance interface name field, enter the text label of a local interface on the Appliance.
    3. In the Options window, select Mac OS X. Repeat these settings in the Overlapping IP Addresses area of the SecureConnector tab.

      See Deploy SecureConnector in Networks with Overlapping IP Addresses for more information about these settings.

  3. Use IP Reuse Domains to Assign Overlapping IP Addresses to Appliances.
  4. Configure Switches and Controllers in IP Reuse Domains.
  5. (In Operational Technology / automation environments) Map IP Reuse Domains in Operational Technology Environments. When the Operational Technology plugin and other eyeInspect components are deployed in your environment, you must map the IP Reuse Domains you define in the eyeSight to the IP Reuse Domains defined in Forescout eyeInspect components.
  6. (Optional) If you use Splunk to process data from the eyeSight, you must review and edit Splunk queries. See Reference IP Reuse Domains in Splunk Queries.
    Once you create and use IP Reuse Domains, you cannot disable support for overlapping IPs until you remove all IP Reuse Domain assignments and delete all defined IP Reuse Domains.
