      Not really, if it's actually a static IP set the WAN to static and configure the IP, subnet and gateway.

      If it's supplied to you a static dhcp lease then you don't have to do anything.

        Every 24 hours this is beyond frustrating

        3 pfsense routers all the same issue now

        So according to the redmine fix isn’t released until version 2.5?

          It's not at all clear that's what you're hitting. When it goes down what do you do to re-stablish it?

          If that's your only WAN connection you can just disable the 'gateway monitoring action' on the gateway. That will keep the monitoring stats to prevent it reloading everything whenever the gateway stops responding.
          You should probably also set the monitoring IP to something other than the gateway. The gateway may well drops pings under load.

            i turned off gateway monitoring entirely yesterday and it still went down early this morning

            i go to interface tab. release, renew and the connection instantly comes back online

            here are my findings the Nokia ONT is changing the local address of the device every 24 hours. when it changes Pfsense says the wan goes down, and everything stops working. i have no way to communicate to the ONT by webqui or ftp etc. since they willl not release that to me.

            the last setting i just changed under wan is : Block private networks and loopback addresses UNCHECKED

              Ok, what does the system log show when that happens? Or the DHCP log?

                the 10.92 device is the ONT modem. which as you can see the address is changing

                    I don't see a 10.100.x.x IP address those there. you mean the 100.92.x.x address? That looks like CGN.

                    It looks like the WAN address is changing, which is not unusual. The addresses involved there seem to be the WAN and it's gateway, I would not expect to see an IP for the local modem device at all.

                    The DHCP logs are hard to read in that format. We are only interested in the dhclient entries. They might be in UTC vs whatever timezone your other logs are in. Really we need to see the dhclient entries in the dhcp log and the system log entries covering that same time span to see what triggered the renewal, or lack of it.

                    If you're hitting that bug I expect to see the link fail or the lease force renewed for some reason in the system log.
                    Then the dhclient start in the dhcp log but fail to get an IP and timeout.
                    Then some error in the system log.
                    Then nothing until you manually restart dhclient.

                    I'm not seeing that though, from what we have so far it's more like the remote dhcp server is handing you a ludicrously long lease and then expecting it to renew sooner. This entry:

                    dhclient
93554
bound to 100.92.204.194 -- renewal in 43200 seconds.

                    Shows a 12h lease though. pfSense would normally attempt to renew it after half the lease time. If you filter the dhcp log for only dhclient process entries I expect to see it renewing every 6h.

                      is there a way i can get you the logs you need by the var/log area easier?

                        Is that two different devices? On two separate connections? They have the same IP address but only 6mins apart....

                        One is given a 12h lease but the other only 30mins.

                        I think you may have some conflict there....

                          same equipment. the new sg 3100.

                          is there something i can change or look at to remedy this?

                            So that is two excerpts from the same dhcp log on the same device?

                            The time stamps are confusing, what order should those be read in?

                            Both those show successful renewal though which is not what is expected from the dhcp bug we referenced.

                              same 3100. same device

                              i pulled them directly from var\logs i copied them to a word file. ctrl + f what you wanted to see and pasted it here

                              read top to bottom

                              i am really hoping a static IP address from the provider will resolve this

                              called my isp to see if they could enable the static today. not possible i have to wait until tomorrow at 9am EST :(

                                In the dhcp logs view you can filter by the dhclient process and then just copy/paste them here directly without going through Word (or any other editor).
                                Some of those logs show the gateway not responding to ARP which probably won't be solved by using a static IP. If you can get one though if will obviously solve any dhcp issues.

                                  static ip has been set and active for over 24 hours now. NO issues whatsoever. first time ever with this new internet service.

                                  i will look forward to when Internet Systems Consortium DHCP Server 4.3.6-P1 is updated to 4.4.2 within Pfsense per https://www.isc.org/dhcp/

                                  so all of this is fixed for users.

                                  so to continue using Pfsense i will be paying 10 dollars extra a month until the release..

                                    It's dhclient not the dhcp server. It will be in 2.5 when that is released, it isn't yet in 2.5 snaps as they are currently built on 12.0.

                                      As I said (in the wrong thread)....

                                      stephenw10 Netgate Administrator about 16 hours ago

                                      Ok, good news. The binary part of the fix for this is now in 2.4.5 snapshots:
                                      https://github.com/pfsense/FreeBSD-src/commits/RELENG_2_4_5/sbin/dhclient/dhclient.c

                                      The full fix also requires changes to the dhclient script which can be applied via the system patches package. I have briefly tested that and it didn't seem to break anything.

                                      That patch is here: https://redmine.pfsense.org/attachments/download/2682/pfsense-dhclient-script-patch.txt

                                      If you're able to test it we may be able to include it in 2.4.5.

                                        no problem Sir.

                                        at this time i have no way to test as i am locked in a one year agreement with a static WAN ip address. my issue resolved.

                                        not sure i provided you any good information. feel free to lock this thread and work with the other gentlemen if that seems best

                                          I'm going to test locally but I can only try to simulate a failed dhcp server. It is definitely a bug that would be very good to squash. I'd love to hear from anyone who is hitting it 'in the field'.

                                            @stephenw10 Hello, I feel like I'm running into this.

                                            Quick overview on my situation:

                                            • Currently running ver 22.05-RELEASE on a 2100. (recently updated)
                                            • Ran over 2 years w/o ever having to reboot appliance on Xfinity internet.
                                            • Recent switch to MetroNet Fiber - Internet goes down every 24-36 hours.
                                            • Has happened 3 times so far, feels like it is reproducing reliably within these time frames.
                                            • Manually releasing WAN / renew WAN action on WAN interface - Restores Internet

                                            Trying to figure out a good path forward:

                                            • Pay $10/month for a static IP (I'd rather not)
                                            • Can we script something to automate the release/renew action during the night on a daily basis? (Feels like a hack)
                                            • Is this a bug that can be fixed? (best solution IMO)
