I applied a GoDaddy SSL to our internet facing PRTG server and at the same time changed our probe from connecting via local 127.0.0.1 to remote connecting via the internal IP of our PRTG server.
Since then the Netflow since has reported No data (since 3/31/2011 10:37:41 AM). I installed the Netflow tester on the PRTG server and am seeing netflow traffic arriving over the defined port.
The Netflow sensor is configured to receive on the same internal IP and port it has always been using. What can I do to get this working?
