Suricata or Snort Interferes with Traffic Graph!

It's not the same. The module for realtek is different, it's not compiled inside the kernel so you can compile it as a module and load it inside pfsense. The problem with intel is that it is compiled inside the kernel and you can't compile a new version as a module without rebuilding the entire kernel.

Ah! I stand corrected. Did not realize that. Thought you might could choose either route (module or native).

That's what I am learning ... so, it would be interesting to learn how to compile ... just have to many things on the fire cooking. Hope it gets into FreeBSD 12.1 before releasing 12.2beta. I have a feeling it's maybe more how Netmap and Snort work causing the traffic graphs issue.

netmapdevice that is the root cause. If the traffic graphs are important to you, switch over to Legacy Blocking Mode and they will return to operation. Legacy Mode does not use thenetmapdevice, and thus those internal FreeBSD networking plumbing changes required bynetmapdo not happen and therefore traffic graphs can work. -
@bmeeks Okay Bill, I heard from the Netmap developer who stated that "with FreeBSD12, Intel NICs switched to iflib as a driver, and this had an impact on netmap, because now netmap support for these NICs is directly provided by iflib."
My hope is that pfSense developers will make sure that all NIC drivers will be updated for 2.5 release. As I had stated I can do without the fancy traffic graphs during the beta testing ... for the release, it must be fully functioning.

I wouldn't depend too much on the pfSense team tackling netmap compatibility in a NIC driver. They use what comes in with FreeBSD pretty much as-is. If you want to lobby for good netmap support in a NIC driver, better to go upstream and open a ticket with the FreeBSD team directly. I'm not familiar with that particular driver and have not researched it, but in some cases the manufacturers write and support drivers for various operating systems and not the developer team of the particular OS.

No, no ... that's not what I am saying and not their responsible. What I am saying is that as a firewall developer, pfSense should make sure NIC drivers are updated as that is the essence of offering a good firewall platform.

HOORAY ... traffic graphs are working; so. I wonder whether FreeBSD 12.1 stable has the latest Intel i350 NIC ... will check later!

Okay, I see why traffic graphs are working ... Netmap broke!

What kind of Netmap errors do you see? Is there anything in any error messages about using the wrong Netmap API?
Just wondering because a Snort user on pfSense-2.5 testing the new Inline IPS Mode reported netmap is broken there and gives a "wrong API" error.
This will be from the recent move to FreeBSD-12.1 for pfSense-2.5 snapshots. Will work on getting it sorted out, but may take some time.
