QRadar: Reverse Flow Direction (QFlow and NetFlow)

Troubleshooting


Problem

The Network Activity tab displays flow direction for certain flows in the wrong direction. Traffic originating from the server might be reversed to make it look like the flow originated from the client.

Symptom

From the Network Activity tab in QRadar, the flow directions of certain flows display in the wrong direction. For example, NetFlow data for inbound firewall deny traffic that should be R2L displays as outbound traffic (L2R).
