Add Public IP addresses to the Corporate Public IPs list
Illumio supports Network Location Awareness for endpoints. To enable your Endpoint VENs to detect interfaces connected to your corporate network, you must specify in the PCE (Servers > Workloads > Corporate Public IPs) the public IP addresses that your corporate network uses for endpoints. Once you've specified these IP addresses in the PCE, Endpoint VENs send network profile detection requests to the PCE. These requests (as seen by the PCE) appear to originate from your organization's public IP addresses.
For details, see "NLA Support for Endpoints" in the Endpoint Concepts Guide.
Go to Servers > Endpoints.
Obtain workload interface information:
Click the workload you're interested in to open its details page.
On the Summary tab, scroll to Interfaces.
Make note of the IP addresses labeled (External) (Public) that you want the PCE to classify as Corporate.
Go to Settings > Corporate Public IPs.
Click Edit and enter the desired public IP addresses in the Addresses field as single addresses or as CIDR blocks (click the tooltip for formatting help).
Click Save.
