I'm seeing quite a lot of messages below in solarwinds, and we can't find the root cause of it.
NetFlow Receiver Service [INPNSSOLPOL01] is receiving flow data from unmanaged interface '#1712' on shanghai-o-w-wan.net.plm.eds.com and it does not support SNMP. Click the "Add this interface" to manage interface and process its flow data.
What we already did and find out!
I have multiple netflow collectors, we are seeing this issue from 4 netflow collectors. If i'm sending netflow to my collector in Emea i don't have any issues.
All my solarwinds servers are in a DMZ behind checkpoint firewalls.
Because i can send netflow to a netflow collector that is working i'm quite sure it isn't the router. but we can't find another issue.
Does anyone has a tip where to look?
We are thinking on the firewall, but we don't know what it could be on the firewall.
