      @gemeenaapje said in Pfsense not responding to large packet pings:

      70 fragments received

      That doesn't look like enough...

      What are the NICs you are passing though? How do they appear in pfSense in pciconf -lv for example?
      I could definitely believe this is some NIC hardware offloading or driver issue.

      The frame size us not really relevant here. I would expect to be able to pass a 65K packet in fragments over a link of any MTU size (within reason!). As long is it's correctly fragmented and assembled, which seems to be failing here.

          Sorry I was mistaken also in that the VM NICs are connected in the guest. As backups I think, it's been so long since I set them up I forget.
          For the HP SFP+ NIC, one connects the server to the main switch (fibre). The other connects straight in from my fibre ISP

            Do you see the same thing if you use the vmx interfaces instead or is it just on the bxe NICs?

            Do you have all the hardware off-loading disabled?

              I tried disabling the "disable" button (so enabling offload) one by one but that didn't help. So I disabled offloading again.

              The router is being used for a web server I run at home so I can't risk changing the settings and swapping NICs or my customers will get upset. Also took me so long just to get this working with all the vlans tags and stuff coming from the ISP.

              Is there anything else I could test?

                Yeah ;)
                Change the title of the thread, as it is pretty clear by know that "big packets" is a hardware/driver issue.
                Plenty of proof shown above that pfSense itself can go to 65xxx.

                Well, let's say you're nothing finished yet.
                Go bare bone with pfsense, exclude the VM from the configuration and you're ok.
                The VM support might be able to tell you if very big packets are possible..

                No "help me" PM's please. Use the forum, the community will thank you.
                Edit : and where are the logs ??

                  @gertjan Can't change title, too much time has passed it says.

                  Other VMs respond fine to 65500 over the network. It's just pfsense which is using the direct passthrough of the additional NIC card.

                  It must be the drivers then, I just don't know where to start with it :-/ Linux is so difficult.

                  Having the VM gives me a huge advantage over bare bone in that I can, if necessary, quickly roll back broken upgrades or changes. I've done this many times and it reduces downtime for my business.

                    Ok something just came back to me!

                    I'm using the drivers on the pfsense box, not the VM. So the pfsense OS controls the drivers.

                    The commands for the drivers are here:
                    https://www.freebsd.org/cgi/man.cgi?query=bxe&sektion=4

                    I see settings there for offloading too.

                    Is it necessary for me to change some of these settings or should the normal web config page for pfsense control these too?

                    Here's a dump of some settings:

                          Strange, it looks like offloading (and other) settings are different for WAN vs LAN.

                          I've no idea what I should be using though.

                            Do that have the same capabilities? Try: ifconfig -vvvma

                            Are those vmxnet NICs the pfSense VM has assigned currently?

                            If not try assigning one to something and see if that responds to large packets.

                            This seems likely to be an issue with the bxe driver or the NIC itself but we need to confirm that by, for example, showing vmx is not affected.
