      Thanks for your response.

      Firewall current kernel version is FreeBSD 14.0-CURRENT amd64. We are running pf sense in physical machine.

      our issue is below - FYI.
      only If a few users using connecting in the firewall, it's working fine. When connecting more users in firewall, only we can able to use the internet, cant access another network (ipsec network/ openvpn network). After rebooting the firewall, everything is working fine

        Does it happen immediately or after the firewall has been running for a while? Does the interrupt load increase slowly?

        What NICs do you have in that box? I can see re0 there.

            How many users? Are you using the Captive Portal?

              We are not using captive portal. Around 50 devices are connecting in LAN.

              95fdf01b-17eb-4dbc-85cb-af793e43681a-image.png

              Interrupt load increases as number devices connection increase in LAN.

              "LAN in" Traffic has reaching till 300 M as cpu interrupt load increases.Then we need to reboot firewall.

                Is it all Realtek NICs?

                  We are using three NIC.

                  We are using two WANs and one LAN.

                  WAN1 is Intel adapters
                  LAN is Intel adapters
                  WAN 2 is Realtek adapter

                    Are you load-balancing traffic between those WANs?

                      No, We are not doing a load balancer as secondary WAN has less bandwidth.

                      FYI - We have updated now the version to 2.7.2

                              Our Network has IPsec VPN, and OpenVPN. I can access the firewall via web GUI and SSH, IPsec network, and Open VPN Client.

                              Once issue has arrived, I can't able to firewall via SSH, web GUI, IPsec Network, and OpenVPN client but all existing devices can connect to the internet continuously without any issue..

                                Can you connect to the console to check that? You captured the top output above.

                                  I couldn't access the console, it froze just like SSH. After rebooting, I was able to access the console.

                                    How did you get the output from top then?

                                      After a few seconds of the above output, I noticed that the console froze.

                                        Hmm, you might try entering 'ctl+t' at the console. That can respond when nothing else does. It should show what process is using the CPU cycles.

                                          I attempted everything, but I was unable to receive any output from the console.

                                          I noticed bandwidth usage, Below Image is when there was no issue.

                                          "The images below (bandwidth and CPU load interruption screenshot) were taken before the issue occurred. When issue is arriving,"Lan in Bandwidth " will be reaching a maximum 300M consistently as the image has 170 MB.

                                            Ah, maybe it really is just slamming the firewall with traffic from LAN then. If you disconnect the LAN when that's happening does the console become responsive again?

                                            Is LAN igb0?
