Netflow over VPN tunnel

marcinw — Mon, 17 Aug 2020 10:15:04 GMT

I am trying to force 1550 SMB device to send netflow traffic (v5/v9) to collector over VPN tunnel, but it is not working , as a netflow collector I use PRTG. I can collect flow from edge device with no problems (directly connected).

SMB config

add netflow collector ip 172.16.100.200 port 9996 export-format Netflow_V5 srcaddr 192.168.1.1 is-enabled true

question: is it possible to run netlow through VPN or I have to put Netflow collector "outside" and use external IP addresses of collector and SMB ?

thanks

Marcin

Netflow is a known limitation currently, please see sk159772

Thanks for letting know, I just checked with old 1100 and 77.20 and Netflow is working … do you know maybe when this problem will be fixed in 80.20 or higher ?
