However pfflow as per article i quoted seems to be working.
So it seems the implementation of netflow in pfsense is not compatible with solarwinds. Has anyone else run into this situation, and can you suggest a fix?Īnd when i looked into pdu of netflow packet generated by pfsense i could see that the source/destination IPs and ports are coming through, but the InputInt and OutputInt and ToS show zero. I'm definitely getting a steady stream of NetFlow data from the Linux box, but NTA doesn't appear to be accepting or processing any of it. When I run a WireShark capture, I get something similar to what you see above - the source/destination IPs and ports are coming through, but the InputInt and OutputInt and ToS show zero. The Linux box is using SoftFlowd to format the NetFlow stream and send it to my Orion NTA server. We have a network of 3750 switches that won't do NetFlow, so we set up SPAN ports and pushed the traffic to a Linux box. I have a similar problem to the one shown here. I tried ManageEngine's NetFlow Analyzer and that worked fine but I'd like to use the Solarwinds tool as it's so lightweight.īesides i also tried wireshark on nms machine running solarwind to see if it was seeing any netflow packets. Can see the pfSense device in the Solarwinds page but not showing any Flow Type. !(/public/ imported_attachments/1/solarwind 2 device detected and traffic on interfaces shown but error when starting netflow I can't help but I am experiencing the exact same problem. !(/public/ imported_attachments/1/solarwind 2 device detected and traffic on interfaces shown but error when starting netflow capture.PNG) !(/public/ imported_attachments/1/solarwind 1 snmp test pass.PNG_thumb) !(/public/ imported_attachments/1/solarwind 1 snmp test pass.PNG) !(/public/ imported_attachments/1/netflow settings -2 on pfsense.PNG_thumb) !(/public/ imported_attachments/1/netflow settings -2 on pfsense.PNG) !(/public/ imported_attachments/1/netflow settings on pfsense.PNG_thumb) !(/public/ imported_attachments/1/netflow settings on pfsense.PNG) I get the error as shown in last picture. My configs are given in below screen shots for both pfsense and realtime netflow analyzer. I enabled netflow on pfsense and installed solarwinds netflow realtime analyzer to get a feel of pfsense netflow cababilites.
