      @bingo600:

      Can you ping the pfSense ip address , on the affected untagged vlan, while the problem is there??

      A lan wks -> pfSense ip FAIL
      pfSense -> a lan wks FAIL
      pfSense -> a tagged lan server on the same port as the untagged lan SUCCESS
      A lan wks -> a tagged lan server on the same port as the untagged lan SUCCESS

      Like that.

        I now moved my LAN from untagged to tagged (I tagged it on pfSense and on the switch). It will be a bitch if my switch dies to recover, but theres always something you can do over the terminal.

        Anyway, let's see if this solves the issue. Then we know that VLANs and raw LAN's and pfSense and Watchguard and Procurve donät work together well.

          Some people say don't mix tagged and untagged traffic on an interface for a reason.

          I would suspect an ARP issue there, but those intervals are awfully short for that. Could also be a simple no carrier on the ethernet interface. Have you tried another cable? Another switchport? But if it is only the default VLAN and not the tagged interfaces, that pretty much rules out layer 1.

          Dealing with a tagged port is not really a bitch to deal with if you have the right tools.

            ARP would've been my guess also, but then I don't really understand why it only starts after a while, and then the problem doesn't go away by itself - and the cycle is quite short as you said. But let's see.

            The bitchy part is mostly if I need to remove the fw and hook up a laptop directly to the LAN, then it will require a bit of fiddling to get that going. As long as you document the VLAN's it's not such a big deal. And perhaps the correct way is to use the switch to handle the mixing and matching of VLAN's on the switch ports and then just either show all tagged or all untagged to the firewall.

                So now everything is pretty fucked until I once again reboot the firewall.

                  When the problem (which is now different but the same) occurs, the firewall can now ping everything so no problem there. But now I lose

                  • VLAN (LAN) -> ovpns5,
                  • VLAN (LAN)->VLAN (SERVERS1) and
                  • VLAN (LAN) -> VLAN (SERVERS2).

                  VLAN (LAN) to the internet is all fine and working.

                  There has to be some way to debug this.

                        As far as I know, almost nobody is using those sk NICs.

                        At the same time I haven't heard of anything like what you're seeing either.

                          Why are both of those on link #11?

                            1.1 is the router itself
                            1.3 is a virtual ip
                            2.21 is a virtual ip

                            192.168.1.3/32 LAN  IP Alias Virtual IP for wpad.malmberg.fi
                            192.168.2.21/32 LAN  IP Alias Virtual IP for wiki.malmberg.fi

                            I also realized that I have had it defined as 1.3/24 instead of 1.3/32 - this I have now changed.

                            I have run your suggested netstat -command BEFORE and AFTER this change.

                                    1.1 is the router itself
                                    1.3 is a virtual ip
                                    2.21 is a virtual ip

                                    192.168.1.3/32    LAN    IP Alias    Virtual IP for wpad.malmberg.fi

                                    So you're playing games with multiple Layer 3 networks on VLAN 5 and you are having problems. Perhaps don't do silly things like that. Makes me wonder what other questionable design decisions you have made elsewhere. Seems they are coming home to roost. What kind of switch are you using? If you post more packet captures please indicate where they were taken and how.

                                      So, the 192.168.2-base ip is now gone. I will look into adding a network solely for my HAProxy addresses some other way, perhaps using a VLAN which is only available on pfSense or something along those lines. But I will leave that for now as it most obviously can be a part of the problem. I added 1.6/32 as a VIP instead to serve my wiki.

                                      My packet dumps are from pfSense.

                                      My switch is a Procurve 2848 (J4904A).

                                      Let's see if the removal of the VIP makes a difference.

                                      It would be foolish to say that this was the only questionable design I have made, although most of my decisions are preceded by somewhat thorough investigations.

                                        From pfSense,  capturing 192.168.1.1 this time.

                                        The pinging is done from 1.191.

                                          I would try a different NIC. Or capture on a monitor port on the switch and see if the pings are really going out on the wire.

                                          Almost nobody uses those sk NICs.

                                            I'll go ahead and move my ports around a bit later tonight just to cross out the possibility of hardware failure.

                                            I've liked the idea of using these Watchguards as they are "proper" pedigree firewalls. I have been looking at migratiing to an XTM-series, but I just had huge issues getting the latest nano-release even starting on that one.
