Sending NetFlow data through encrypted IPSec tunnel
« on: June 26, 2019, 08:15:06 pm »
I wanted to know if it was possible to encrypt NetFlow data from the OPNsense box to an external NetFlow Collector using IPSec ?

For the time being, It looks like NetFlow traffic does not enter into the VPN and thus can't be sent remotely through IPSec.

Do you have any idea how to solve this ?


Sincerely yours.

Hi Greg,

It would certainly work with routed IPsec:
