• When you add VPNs to a task, NTA will show you a list of all devices that NTA knows about. The
list is generated from the devices that have been added to NTA using the Device Management
feature. If the devices you want to select do not appear on this list, it is most likely because the
device has not been added to NTA or it has not been selected in the NTA server configuration
found under server management. For more information on adding a device for traffic analysis to
NTA, see " Device management ." For more information on selecting devices in NTA server
management, see " Modifying an NTA server configuration ."
• You must enable network flow data on the devices for the VPNs you want to monitor and report on.
Managing VPN traffic analysis tasks

to receive. Effective management of tasks results in the reporting you need. The following information
describes the process for adding, modifying, or removing VPN traffic analysis tasks in NTA.
