Hello.
I installed Netflow Analyzer on Windows 7 32b. And saw on my Dashboard information about my router. Then I installed Netflow Analyzer on Red Hat Enterprise 6.1 and I didn't see information on Dashboard, "No device is currently exporting NetFlow / sFlow Packets at Port 9996". I used same ip addresses on the Windows and Linux. I used "tcpdump port 9996" and I saw packages from my router.
