      I forgot, it was saying the WAN was not responding, but the ONT (fiber optic "modem") showed it was up and ready. It did not require recycling to get the connections to be re-established.

        Hmm, so dpinger is being restarted. Is that the main system log or the gateways log? I would expect more in the system log that might show why dpinger is restarting.

        However it also shows complete packet loss after some time. Do you have to reboot pfSense to recover from that?

        Are those 100.x.x.x addresses real? That looks like you're behind CGN. We have seen CGN gateways object to the monitoring pings pfSense sends. Try setting an external montoring IP on the WAN gateway like 8.8.8.8 or 1.1.1.1.

          As far as I remember, that was system log not WAN.

          The 100...* are from ISP (MetroNet Fiber Inc, aka Metronet). I've been seeing those addresses for as long as I can remember. And with other gateway software I had with a different network device I built, heart beats would fail and I'd end up failing over to a second ISP (Spectrum) and that was using 8.8.8.8. I used various heartbeat type things such as DNS (for resolving google.com) and that would sometimes fail.

          Meanwhile, I have been was looking, and I didn't see where I can override to 8.8.8.8 on the WAN.

          Lastly, what is CGN? I just know enough to be dangerous.

            You can set a different monitoring IP in System > Routing > Gateways edit the WAN gateway.

            CGN is Carrier Grade NAT. That IP address is in the CGN allocated range:
            https://en.wikipedia.org/wiki/Carrier-grade_NAT#Shared_address_space

            It's not a problem in general but it's not a routable IP so you would have issues with incoming connections if you wanted to setup a VPN server for example.

              Crashed again, but it took me a bit to realize it as I was reading a manual trying to determine something for a product I'm devoloping.... Here is the Log (I caused a reboot):

                Looks like you are still monitoring the ISPs gateway IP directly. You should change that to something external. Both to get better monitoring data and because we have seen ISPs that will react to the pings as an attack and block a host device eventually.

                  @stephenw10 Thank you. I'll find the manual and figure this out. This way I learn the product better.

                      Read that, and wasn't sure of everything, but then I went to the Gateway and changed it to use 8.8.8.8 for testing.

                      So I'll let that run for a while. Unless you have other better ideas.

                      But I have to admit, I've learned something here about ISP behaviors. I can now understand why certain things I was doing for heartbeat testing a year or two ago was having problems.

                        Had it happen again after changing to go against 8.8.8.8. I've been a bit busy that's why it has taken me a bit to get the log copied. I think I caught the problem....:

                          Hmm, nothing is shown there really. The gateway monitoring shows packet loss and marked the gateway as down. Then you logged in and rebooted.

                          The NIC did not lose link. Nothing else is logged. Was anything else shown at the time? Or did modem show any unusual behaviour perhaps?

                            To answer your question directly - The modem looked like it was functional. It had the normal data light flickering. No alarm or error light lit.

                            However, DNS and streaming stopped - trying restart of streaming device could not resolve address(es). Ping of 8.8.8.8 failed (done via DOS box from my W11 system).

                            So I checked to see what errors I could find looking at the logs.

                            And that is all I had. So I rebooted with re-root (maybe just plain reboot would also work). And we've been up and running ever since.

                            I will be shutting down the system tomorrow afternoon before we leave for a conference. And I'll bring it all back online when I get back.

                              Hmm, what NICs do you have in that?

                              Do you see errors or collisions in Status > Interfaces?

                                I'm not sure what the Nics are. I have a card with two ports. Don't know who the maker is or what chips they used. Then the MOBO has a port on it.

                                This is what the status shows:

                                  Disable IP6 and reboot the FW.

                                    Thanx.

                                    Interesting. I had disabled IPv6 on all interfaces and thought I had disabled this on the WAN. But there it is, IPV^ config type was not set to NONE.

                                    So I set WAN IPV6 to none. And then told it to apply the change. But I won't be able to do a reboot for another hour or so.

                                      That's only a link local address.

                                      Both of those interfaces are Realtek NICs, re0 and re1, which are known to have issues.
                                      Are those both the add-on NICs? Is the other NIC different? If it is I would try that as WAN.

                                        Note: I will be gone to a convention. I will have this system powered down while I am gone. Will be back 10-OCT-23, but I will have some access to email.

                                          @Wylbur I made the switch from the dual port card (realtek) (mac 00:e0:4c:61:b4:94) to the one on the MOBO (unknown what it is) and it took me a bit to figure out a few changes that had to be made and so far so good (I did this about 30 minutes ago).

                                          This was forced because of some weird problem I am having with a government site so I decided now is the time to do this just in case the problem is with the WAN port.

                                          Nice idea while it lasted. -- But things are otherwise working with this swap.

                                          I don't see collisions, but I do see a large number of interrupts. I don't exactly know what those are (I work with interrupt driven mainframes, so I expect to see interrupts coming out my ears. Every I/O is at least 1 interrupt, then there are various caused by instruction streams, the system timer generates many time interrupts for dispatcher processing...).

                                            Exactly, interrupts are required for the NIC to function so that's not a problem unless the rate is very high.
