My fortigate 800C has version 5.0 build 3608 NTA version 4.1.
I configured to push flows from WAN interface of firewall to Solarwind, but in NTA it show up "never receive flow" I install wireshark to monitor the NIC in Server and I can see the flows from Fortigate. Other netflow sources are OK. See below configuration.
1st config interface - it sent sflow in solarwinds
2nd config interface - has a problem
PLEASE ADVISE. Thank you.
Seeing any unknown sources of Netflow traffic? Try setting the source-ip of the sflow collector to be the same IP you manage your Fortinet with in NPM.
That being said, I opened a ticket once on traffic discrepancies on a Fortinet with Sflow. They wrote it off saying that basically netflow support was limited on anything that doesn't have the NP6 processor, which is most of their product line. I believe this device has the CP8.
