      @mucip said in Internet lost in PfSense but VPN or everythingelse work well?:

      But why? What is the reason?

      Afaik : when upgrading from pfSense <2.7.0 to 2.7.0, this command should have been part of the steps to do after the upgrade finishes.
      The thing is : it was forgotten.

      Don't worry, this situation only happened ones ^^ No need to thing about it anymore.

      No "help me" PM's please. Use the forum, the community will thank you.
      Edit : and where are the logs ??

        Dear @Gertjan,
        I hope so. I already added this command to cron.
        Well I will remove command from cron and check in the near future.😊

          There should be no need to run that command manually in 2.7.2. The pkg scripts run it anyway when it's required.

          How were you testing? If you simply ran pkg update from the CLI the client cert may have expired. Checking from the webgui should never hit that though.

            Dear @stephenw10,
            I updated from WEB GUI not CLI.
            In any case this morning the people said me that there is no internet out from Linux server.
            I applied our famous command "certctl rehash" from webgui command execute menu and everything turn to normal again.
            I will check. If I need to apply same command again than I add this command in the cron and run every midnight.

            Regards,
            Mucip:)

              Hmm, that is odd. The only thing that should help with is local certs on pfSense itself. So access to the pkg repos which requires a client side cert.

              It shouldn't make any difference to routing traffic. Unless maybe that is going via VPN that requires a cert.

                  It seems unlikely the issue is actually cert related. Somehow running that is re-loading something that allows traffic to restart. So I would be trying to determine exactly what fails when traffic stops.

                    Dear @stephenw10,
                    But how? What shoul I check if the internet stops again?

                    Or I need to write script to check internet connetion in pfsense. When the internet lost than I need to run "certctl rehash" command again? I don't know?

                    Regards,
                    Mucip:)

                      You are able to reach the pfSense gui from LAN when it fails yes?

                      So I would first test what pfSense itself can do in that situation. Can it ping 8.8.8.8? Can it ping google.com?

                      If it can then can LAN side clients do either of those?

                        Hi @stephenw10,
                        I made php scipt to check internet connection in LAN Debian server.
                        If not than it will send me an email. Than I will check what's going on in the PfSense.
                        I put this php code in the cron now.

                        Let's see... 😊

                        P.S: But I am wrong! If internet lost how can Debian send me an email?!
                        I need to create script in pfsense and check internet from LAN because I checked before
                        How can check internet connectivity in LAN with bash or php command in Pfsense?

                        Regards,
                        Mucip:)

                          Dear @stephenw10,

                          I may add this php file to cron but it must check internet connectivity from LAN not WAN.
                          Because normally there is internet on WAN but there isn't on LAN unfortunatelly.

                            You can source your test from the LAN IP and that will confirm NAT is working.

                            However reviewing the symptoms you have here I'd be willing to bet it's a gateway/routing issue.

                            What gateways do you have defined in System > Routing?

                            If you have more than one and the default gateway is still set to automatic try setting it to the WAN gateway specifically. It may be switching to one of the others if the WAN ever has an issue.

                                The command would be:

                                [2.7.2-RELEASE][admin@t70.stevew.lan]/root: ping -c 3 -S 192.168.226.1 8.8.8.8
                                PING 8.8.8.8 (8.8.8.8) from 192.168.226.1: 56 data bytes
                                64 bytes from 8.8.8.8: icmp_seq=0 ttl=116 time=6.036 ms
                                64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=12.178 ms
                                64 bytes from 8.8.8.8: icmp_seq=2 ttl=116 time=6.225 ms
                                
                                --- 8.8.8.8 ping statistics ---
                                3 packets transmitted, 3 packets received, 0.0% packet loss
                                round-trip min/avg/max/stddev = 6.036/8.146/12.178/2.852 ms
                                

                                Where 192.168.226.1 is the LAN IP address.

                                However what are you using that gateway on LAN for? You have other subnets behind a router at 192.168.0.1?
                                If that's the LAN IP address it should not be there.

                                  Dear @stephenw10,
                                  I have modem in the office. PfSense gets internet from modem.
                                  Modem IP block is 192.168.1.X
                                  PfSense WAN 192.168.1.99
                                  PfSense LAN is 192.168.0.1

                                  Untill recent 3-5 days everything was OK. But nowadays I have problem I don't know why?

                                  Regards,

                                    Ah, OK then that LAN gateway you have set as the LAN interface IP is wrong. You should remove it, it can only cause conflicts.

                                        Yes, you should only ever have a gateway on LAN if you have some other router in the LAN subnet. And even then it would never be the LAN IP address.
