I have set the Netflow udp port 9995 on ASA via ASDM, and created the new Netflow V9 sensor, and define the same port, Sender IP is ASA, active flow timeout 10mins, samling rate is 1 min as the same settings on ASA. But this sensor always shows grey "unknown". I closed the whole windows local firewall, but it still doesn't work. Any suggestions ? Thanks !

Hi there,
In order to find out if proper and compatible Netflow packets are arriving at the PRTG host, please use our Netflow Tester:

Please post a screenshot from the Netflow Tester here so we can analyze this further.
Best regards.
