Title: No reporting data available for OpenVPN traffic
Post by: myksto on June 28, 2018, 09:11:13 am

Hi guys.
I setup the Insigt reporting feature so that I can monitor traffic from inside my networks.
In Netflow configuration I added my LAN, DMZ and OpenVPN interfaces.
When I go to the Insight function I can see all traffic and graphs for all interfaces except OpenVPN.
I attached screenshot of Netflow configuration and Insigth for OpenVPN interfaces where, you can see, no data is available and I have several OpenVPN connections active (mine too now).

Am I doing anything wrong or missing something?

Thanks and cheers,

Michele.

I don't think the NetFlow generator built into FreeBSD's NetGraph subsystem is particularly equipped for all types of pseudo-devices. It's a bit like the IPS situation, where NetGraph devices don't work as well either...

Not sure if anyone in FreeBSD still works in these parts. They are, sadly, "as good as they get" which means they have limitations and tun/tap devices seem to be part of it.


Cheers,
Franco

Hi gentlemen,

I have the same situation as well on OpenVPN, and luckily, except OpenVPN, it seems i can get the (look-like-) correct data against other interfaces of which all are virtualized.
