      I'm wondering if we could put that information in the loader.conf.local file?

      It looks like the right place to put this is described here:

      https://www.netgate.com/docs/pfsense/development/executing-commands-at-boot-time.html

      I tried to offer an example but Akismet thinks its spam. Let's see if this post will go through?

        boobletins...I read through the link you provided but I'm not sure myself on what the syntax should be to add to the loader.conf.local file. I was looking to use the loader.conf.local file for an interim fix until the FreeBSD developers are able to solve the netmap issue(s) in a future release.

          Look closely at https://www.netgate.com/docs/pfsense/packages/package-list.html there is a package that might help with running a command on system startup.

            Grimson...You're right. I didn't see it. Shellcmd - The shellcmd utility is used to manage commands on system startup. Now we just need the syntax to use.

              Shellcmd just runs commands like they would be at the command line. The only difference is you often need the complete path to the command as it runs as a different user. But you could use:
              ifconfig igb0 -rxcsum -rxcsum6 -txcsum -txcsum6 -lro -tso -vlanhwtso

              That should run OK.

                I noticed that with the release of pfSenxe 2.4.4, there was a dramatic increase of Netmap errors (https://forum.netgate.com/topic/136191/netmap-alerts-gotten-worst-with-2-4-4). I also have an igb network card.

                The major headache is this issue turns into finger pointing...pfSense says its FreeBSD 11.2, Netmap says its Suricata, FreeBSD says its the network card, and Suricata says its Netmap.

                My feeling is since we're ultimately using pfSense, it's pfSense responsibility to ensure that we achieve synergy of a robust firewall with all parts working seamlessly. Inline mode is an important part of firewall intrusion detection prevention system in that it provides a more efficient screening.

                pfSense+ 23.09 Lenovo Thinkcentre M93P SFF Quadcore i7 dual Raid-ZFS 128GB-SSD 32GB-RAM PCI-Intel i350-t4 NIC, -Intel QAT 8950.
                pfSense+ 23.09 VM-Proxmox, Dell Precision Xeon-W2155 Nvme 500GB-ZFS 128GB-RAM PCIe-Intel i350-t4, Intel QAT-8950, P-cloud.

                  It looks like in that thread you seemed to have solved the issue, is that the case? (I ask because I'm interested in knowing if I've solved this issue for myself as well).

                  If you're game, could you give me the output from the following shell commands (case sensitive):

                  ifconfig igb0 | grep CSUM
sysctl -a | grep igb
sysctl -a | grep netmap
                  • How many CPU cores do you have?
                  • Is hyperthreading enabled?
                  • How much RAM do you have?
                  • Are you running Suricata on more than 1 interface? (If so, what's the second interface? Also: run the shell commands above on that interface)

                  I've gone a few days now without netmap errors on either my em0 or igb0 interface with Suricata in inline IPS mode and 2 speedtests / hour. I'm becoming more confident that I have a working configuration, but if we can eliminate them from yours as well that'd be some welcome evidence...

                      Under System / Advanced / Networking, is "Allow IPv6" checked?

                      And how many CPU cores? Is hyperthreading enabled?

                          So here are some initial suggestions. Please keep in mind that I've been working on this for ~1 week (in other words: not long), and I'm not a FreeBSD, pfSense, or Suricata expert.

                          Start by making a backup of your configuration.

                          Do these first:
                          My understanding is that flow control should be off on any netmap interface. You have bi-directional flow control enabled:

                          dev.igb.0.fc: 3

                          Disable flow control on all active interfaces using system tunables. Set dev.igb.0.fc=0 (and dev.igb.1.fc=0)

                          Actively set energy efficient ethernet to disabled:
                          dev.igb.0.eee_disabled=1

                          Actively force IPv6_TXCSUM6 off by adding the following to config.xml in a shellcmd tag:

                          ifconfig igb0 -rxcsum -rxcsum6 -txcsum -txcsum6 -lro -tso -vlanhwtso

                          (see above in this thread for a link on where/how to do that).

                          Edit:
                          To be clear: anywhere I have a command that says "igb0" or "igb.0" you will want to duplicate that for igb1 and any other interface you're running netmap on.

                          So you will need 2 shellcmd lines in config.xml, and two new system tunables for flow control, etc

                          Consider changing later:

                          Set rx processing limit:
                          dev.igb.0.rx_processing_limit: -1

                          It looks like your txd and rxd are both set to 1024 currently, I suggest you move those to 4096:
                          hw.igb.txd=4096
                          hw.igb.rxd=4096

                          By changing your txd and rxd we may need to revisit your netmap buf/ring (memory settings).

                          We may also revisit your interrupt and queue settings.

                            It would be great if you could let me know what happens after the initial changes -- if you continue to get netmap errors or not.

                            If you do, don't jump right to the 2nd section of changes, we should verify that the changes we made above took properly. I learned the hard way that I was putting some settings in the wrong places.

                              boobletins...I apologize for not getting back sooner; other projects. I added the shellcmd line to the /cf/conf/config.xml file as you suggested. I re-enabled Suricata in Inline IPS Mode and restarted pfSense. I ran ifconfig against all four ethernet interfaces on my SuperMicro adapter and TXCSUM_IPV6 was not listed.

                              One thing I find interesting is in the Services > Suricata > Alerts tab, all of the text is now black in color when before making the above change it was all red in color in Inline IPS Mode. As well, there are no entries in the Blocks tab when before making the change it was automagically populated with over 300 blocked IP addresses in Inline IPS Mode. I don't know if this is normal or not. I didn't change any of the Suricata WAN Categories.

                                If you are running Suricata in inline mode, you will not see blocked IP addresses in the blocked tab, as any traffic that conforms to your "drop" rules is automatically intercepted and dropped (as opposed to initially logged, then ip banned as in Legacy mode).

                                The red text in the Alerts tab is letting you know that the traffic was indeed intercepted and dropped (since you don't have any information in the Block tab anymore).

                                That you are missing both blocks and red text means that either no traffic has conformed to your block rules yet, or something has gone wrong.

                                Double check which mode Suricata is running in. Then double check that you have some drop rules defined.

                                But originally the issue was netmap, yes? If so, have you see any netmap errors? Can you complete a speedtest with Suricata enabled in inline mode now?

                                  I guess my "drop" rules are just based on the Suricata WAN Categories I selected/checked? When you checkmark what you want, Suricata applies those rules to the incoming data and drops it?

                                  I'm definitely running in Inline IPS Mode and all of the Alerts entries are in black colored text. As well, all of the text I typed into the loader.conf.local file is commented out.

                                  Yes, the original issue was many, many, netmap_grab_packets console/log messages. At the time of this post, I don't have any netmap errors, yet ☺ . I can actually complete a speedtest in Inline IPS Mode now.

                                    So Suricata is complex and can do many things.

                                    I suggest you read about SID management and check out the SID management and categories tabs.

                                    If I had to guess, I would say that you have a minimal set of "drop" rules in place and just haven't had blocked traffic hit your server yet. When you do, you'll see the red text.

                                    If you want to convert "alerts" to "drops," you'll typically do that in SID management.

                                      Unfortunately, I just received several netmap_grap_packets errors:

                                      netmap_grab_packets bad pkt at 465 len 2147

                                      netmap_grab_packets bad pkt at 777 len 2154

                                      Apparently the shellcmd didn't work after all.

                                        Could you give me the same info I asked for from NollipfSense above?

                                        The results of these commands:
                                        ifconfig igb0 | grep CSUM

                                          When you run with Inline IPS Mode enabled, you have to manually change rules you want to block traffic from ALERT to DROP. You can do that in two places: (1) on the RULES tab with the selected category displayed; (2) using SID Management keywords on the SID MGMT tab. Sounds like you do not have any DROP rules enabled if you are getting no red alert entries. Either that, or as @boobletins stated, your enabled DROP rules have not been triggered.
