The Trellix IPS Manager is installed on a virtual machine in the AWS environment.
If you have the Manager behind a firewall, you need to update your firewall rules accordingly such that ports are open for the Manager to communicate with Sensors, the Controller, and vIPS Probes. For more information on ports used by the Manager to communicate with Sensors, Controllers, and vIPS Probes, see the section Requirements to deploy Trellix vIPS in AWS environment.
