      I recall that the first issue was back in Apr/2019.
      According to https://docs.netgate.com/pfsense/en/latest/releases/versions-of-pfsense-and-freebsd.html,
      I was moving from 2.4.4-p1 to 2.4.4-p2.
      I'm now on 2.4.4-p3.

      But, I'm not 100% sure about it...

      Back to https://redmine.pfsense.org/issues/7645, what was the changelog for the issue?
      Just wondering to identify if there is a regression.

      Thanks,
      Daniele

        Just spent a while looking for it and failed to track it down. I'll have to ask someone who might know directly.

            I've been unable to replicate this in 2.4.4p3 or 2.5.

            Requiring promiscuous mode like that usually implies the wrong MAC address or at least an unexpected MAC. I wonder if the lagg on there altered it for that driver?

              @stephenw10 lagg has been not configured. Without lagg I confirm that this is working

              My lagg is configred with lacp

              Thanks,

                Oh, OK so this only a problem over lagg? In your previous post it looked like you removed cpsw1 from the lagg and a VLAN on that port still only worked with promiscuous mode enabled.

                  Shame on myself,

                  I have made a further test, and this really seems not linked to the LAGG configuration.
                  So, i'll try to upgrade it from scratch and let's see.

                  I will keep you posted.

                  Thanks,
                  Daniele

                    Ah, OK, so possibly an issue with the test outside of the lagg?

                    I'll see if I can replicate the lagg issue.

                    Steve

                      Fast forward to Q3 2021, finally i had some time to reproduce everything.

                      • resetted the SG-1000, installed the pfsense plus 21.02.2
                      • bringed up ssh
                      • create a rule to allow everything in floating (with quick)
                      • NOT configured the lagg
                      • LAN on cpsw1
                      • setup one vlan per NIC (cpsw0.10, cpsw1.11)

                      tests:

                      1. reboot
                      2. ping is working on LAN (untagged) but not not VLANs (tagged)
                      3. ifconfig promisc on cpsw0
                      4. ping is working on both cpsw0.10 AND cpsw1.11
                      5. reboot
                      6. ping is working on LAN (untagged) but not not VLANs (tagged)
                      7. ifconfig promisc on cpsw1
                      8. ping is working on both cpsw0.10 AND cpsw1.11

                      reproducer:
