      @stephenw10 It has finally locked up twice now since the change to using the MOBO ethernet port. This is what I captured before a reboot (and I do not understand the error):

        @Wylbur re1 = realTek 8168/8111 as is re0. re0 is now on the MOBO.

        What does anyone recommend for a better adapter? I'd like to try to replace the dual port card I have.

          Any Intel 1G NIC would be far better.

          Nothing really logged there beyond the packet loss alarm. No watchdog timeouts logged.

            I have had this problem happen again -- Loss of connections with ISP (within the last 15 minutes) and I have an Intel chip dual port ethernet 1Gb card. The following is what the syslog shows (I did a reroot reboot):

            Note that I stopped SNORT because of some anomalies with a US Gov't web site. Snort was not causing it just haven't turned it back on.

              Are you still running the Realtek NICs?

                Negative. I am running an INTEL dual port NIC. Both LAN and WAN go through that card. The MOBO has a port, but it is Realtek based so I decided to not use it.

                  Ah OK. So the WAN shows a gateway alarm there then you logged in and rebooted. I assume after reboot the WAN gateway shows as up? And if you did not reboot it stays down?

                    That is correct.

                    So I know something is not right when a streaming device stops. Or at your desk you tell your email client to fetch mail and it says it can't connect to .... Or a browser says the server is no longer responding....

                    Then I go and pop up the tab into pfSense and check status, and look at the log. When I see that message, I know the only way out (at this time) is reboot, so I also select reroot. Maybe that is over kill, but things come back up quickly after that and nothing is hung.

                      Which message specifically? The dpinger packet loss alarm?

                        This one or one like it:
                        Gateway alarm: WAN_DHCP (Addr:8.8.8.8 Alarm:1 RTT:24.697ms RTTsd:.955ms Loss:21 <<< Loss will be at 21 or higher

                          Ok, I think we're going to need to dig into exactly what is failing here. Since there's nothing else logged when this happens it doesn't appear to be NIC link issue or routing change etc.

                          I think I would try running a packet capture on the WAN when it's in that state. See what's actually leaving there and if anything is coming back.

                            I've been looking at tracing and packet captures. But I'm not seeing what I would have expected. And it may be because of a difference in terminology. For NDM or Connect:Direct (a Managed File XFER product) I would turn on tracing for a specific thing, having to do with hand-shake or TCP|UDP packets for a specific address. In this case it is the WAN port that I need to trace. Is this Dataplane packet tracing? Also note, I have blocked IPv6 in/out for our environment should that be a possible problem. And if I understand correctly this is all CLI, so it can't be set up from the GUI, right?

                              Here you are just capturing all packets on the WAN to what, if anything, is there. I expect to see either the gateway monitoring pings or ARP requests at least. Probably not much else.
                              But if you see the upstream gateway sending ARP requests for example that gives us a clue.
                              You can run the packet capture from the webgui:
                              https://docs.netgate.com/pfsense/en/latest/diagnostics/packetcapture/webgui.html
