I have a netflow v9 sensor for one device(device1). And a netflow custom v9 sensor for another device(device2). The results for the custom sensor for device2 are displaying the exact same thing as the sensor for device1. Is there a method for unassociating the sensor for device2 from the sensor for device1?

Hello,

Thank you very much for using PRTG. If you already have separate Netflow Sensors (one for each firewall), and all are listening on the same UDP port, the traffic will be added up. You can filter per firewall then by using the "Sender IP"-Field on each Firewall, and enter the IP of the sending firewall on each Netflow Sensor. Please be aware though, that this will not filter backwards / historic data entries.

best regards.
