      @gawainxx said in WAN interface stops working every few days.:

      • Reset to factory and rebuild the config from absolute scratch, by hand rather then importing it?

      If your network setup isn't too complicated, this is what I would have done by now.

      If you choose this option, don't put ANYTHING into the default config. Just run it bare and see if it still fails. If it does, this is a good sign that something is wrong with your pfsense box itself.

        What sort of hardware issues do you think could potentially cause this behavior?

        I've ran a Memory and CPU torture test and no issues where, I've tried several different nics for the WAN. First one was onboard, second was a broadcom PCIE, current one is an Intel PCIE. I've however been using the onboard NIC for LAN VLAN's this entire time, could the broadcom onboard nic somehow be indirectly effecting WAN?

        Restarting the pf sense router or the ONT will resolve the issue, I'm left scratching my head

        .P.S. the server is on a Line-Interactive UPS.. (I did also test if the UPS was causing it)_

        If the issue happens again with that AP and daisy chained switch disconnected, I'll grudgingly set the router back up from scratch with the exception of the firewall config (which I'll comb through by hand prior to importing)

          Could a NAT rule for a Nintendo switch cause any issues?

          I also notice there are some shaping rules burried in my config .xml which are not visible in the GUI.. Hmm

            No, an outbound NAT rule will not be doing anything.

            Traffic shaping is far more likely. Assuming it's anything config related.

              Ok, I reloaded everything, with the exception that I imported the VPN config, certs and firewall rules because those would have been a royal PITA to rebuild.

              Problem still persists.

              There have been several times in the past few weeks where I suddenly got very high latency and packet loss but it resolved itself after a couple of minutes.

              Somehow using my main workstation for the first time in a day seems like it could be attributing to the issue, it seems like the behavior occurs 5-10 minutes after I've powered that system on...? I can't think of why a single system could cause the WAN interface of pfsense to behave like this though?

              I'm getting towards the end of my list of ideas and could desperately use some solutions.

              I've just connected my centurylink C3000z in bridge mode and placed pfsense behind that, seeing if perhaps letting the centurylink "modem" handle the VLAN tagging makes some difference?

              Here is a copy of my config, I have scrubbed anything cert or credential related from it.
              1599534090821-config_scrubbed.xml

              I'm getting down towards my last options which would be to purchase another desktop for the explicit purpose of temporarily running it as the pfsense sever to test if it's somehow a host issue or using my spare ASUS router (This would cause me a lot of headaches as I would have to reconfigure my entire home network, stripping out vlans and resubnetting all of my vms, devices.)

                The TTL exceeded message you are seeing from upstream when it happens still makes it look like some upstream routing problem to me.

                If you are able to use the ISP router in there as a test though that would rule out an obscure pfSense issue.

                    It's 2.4.5p1. Because, yeah, this sure looks like #10414 in 2.4.5. 😉

                      I'm not using the ISP router for routing or dhcp atm, just handling the vlan tagged traffic to see if it has any influence...
                      I may have to suffer and try running a double NAT for a week or two though to see if the behaviour persists when ISP router handles traffic.

                        Interesting, I'll need to take a close look at that thread later. The webui does definately take several seconds to load when I initially try to access it while the gateway issues are occuring

                          If you are somehow hitting that still you would see high latency to the firewall itself from a LAN side client everytime you ran Status > Filter reload.

                            hmm, manually doing a filter reload caused the ping to firewall to jump from 1 to 100ms for a single ping but nothing noteworthy aside from that.

                            I am however still using the ISP "Modem" (Truly a router) to handle the VLAN tagging, which i set up last night.

                              @gawainxx I already faced this kind of trouble.
                              The latency starts growing until th Wan interface stops working.
                              A (not) solution was to turn monitoring IP to of.

                              Then I changed my ISP and both, the trouble and the ISP, desappeared.

                              I love pfSense!

                                To verify, you changed the monitoring function/action off?
                                I'll add that to my to-do list.
                                Unfortunately the speed with my ISP is awesome and the pricing is reliable, unlike Comcast. I'd rather not go to Comcast if I can help it as it's tiresome to negotiate pricing once every year.

                                  One more thing to check, is it possible that your machine is overheating? Specifically the network card? I've had a situation where the network card was malfunctioning and a reboot of the machine would not fix it. I physically had to shut the entire machine down (remove power) in order to fix the problem. I think it stems from the network card in particular overheating. If you have something blocking the airflow or the processors on the network card do not have heatsinks, then perhaps it's that. I had issues with a Broadcom card just generally so I switched to Intel and haven't looked back, except for when I have an overheating issue. Sounds like you have the issue at or around noon? Go on eBay and get something like the INTEL EXPI9404PTL PRO/1000 PT Quad Port PCIe card for like $30. Intel makes the best gigabit cards in my opinion.

                                    I doubt it, the r210 ii has excellent airflow and mobo, proc temps are all green.

                                    This has happened with onboard as well as 3 different PCIe NICs 2x broadcom, 1x Intel all different chips

                                      Did already established connections continue to work without issue?

                                      IE if I'm using splashtop and connected controlling a remote desktop I'm able to continue using it with no speed delay, however I'd be unable to reconnect once I disconnect.
