      just keeping everyone up to speed. No idea why this would make a lick of difference but I hard set the MTU on the labsystems interface to 1500 MTU and now speedtest.net will load and run to full expectation. Now just gotta finish sorting out the last few sites. Heading the right direction.

        I went line by line on the Cisco ASA config and found nothing that would be special by any means. I'll start looking at the analysis difference between the two sets of captures.

          what is this labsystems exactly - there is nothing labeled that in your drawing.

            What I recently got a warning from a "vexpert" line that there are problems with the I219-V Intel stuff in virtualization environments from the beginning, problems all over the place....

            these are only somewhat mitigated by the Fling community driver, it may be related(?)

            https://www.virten.net/2017/02/heads-up-esxi-not-working-on-7th-gen-kaby-lake-intel-nuc/

            same is the case for some Linux flavours with this Intel
            maybe there is something in this

              Labsystems is the vlan where my VMs live. 172.16.0.0/24. Connects from PFsense to the TPlink switch to the vm hosting system and the rpi.

                  And where did you set the mtu exactly - on what? What was it that it wasn't the standard and you had to "hard code" it?

                    It only somewhat helped. Afterward I could get speedtest.net to render.

                      @dfinjr and if you ssh to your pfsense and do a ifconfig - what are all the mtu for all the intefaces showing?

                      Looking at your ciscoasa pcap - the frame sizes are sill OFF.. 1434 and 1380?

                        doesn't look like this output shows the MTU:
                        25008f12-9903-4a15-a3ab-84244fd3fd6d-image.png

                        is there another command I can run in order to give you what you're after?

                        Yeah I bet the frame sizes were still off. No idea how the ASA was compensating for it.

                          @dfinjr that is not an ifconfig command

                          ifconfig.jpg

                          from the main pfsense menu, do 8 and then run the command

                              rather so, enter the shell (8) 😉

                                  this looks good....
                                  we're not moving forward, we're stuck in one place, I can think of two things:

                                  1. do you have a good quality USB NIC in your hands?
                                  2. VirtualBox temp install

                                    I agree. breaking out another system with mint/virtual box on it to test. stand by for a sec and let me build something up.

                                      Yeah, interesting. Something is restricting the MTU there.

                                      Also interesting is that the pcap on the VM host sees the traffic both ways with the Cisco in there.

                                        While we're waiting...

                                        Would you expect to see a block between two systems on these two vlans?

                                        751843a1-910b-4b65-849b-f90d5dc4c693-image.png

                                        got something interesting going on here and I wonder if it is the same thing we've been seeing...

                                        As I mentioned once before, I am a Bigfix sales engineer.

                                        The DMZ client can ping/curl everything I would expect for the system to connect to the Bigfix management server yet I am seeing it fail.

                                          What's the advanced option you have set on the LABSYSTEMS rule?

                                          I would not expect anything blocked, do you see blocks in the firewall log?

                                            It's likely this, from troubleshooting:

                                            Maybe so:
