      It might there have been numerous fixes between 2.7.0 and 2.7.2. But even if it doesn't you need to test in 2.7.2.

                pretty sure this is the upgrade problem and I recommend the update over ssh!
                https://forum.netgate.com/post/1140955

                Maybe ntopng is the CPU load issue, try to disable/remove it.

                  Ntopng service has already stopped. I will install the 2.7.2. over ssh
                  how do we find the CPU usage issue and network connectivity issues ?

                    No idea, sorry. This must depend on your setup.

                      Thanks.

                      Before upgrading the version. It was working fine, there was no CPU usage and network connectivity issue s mentioned earlier.

                        There is something else, did you mention somewhere you use a VM ?
                        If so :
                        The pfSense from last decade, 2.4.5, used an very ancient FreeBSD kernel.
                        The recent 2.7.2 uses what, freeBSD 14 or even 15 ?
                        The hypervisor model or VM settings should be 'updated' (upgraded ?) also.
                        if not, bad, or even horrible network virtualization has been seen before.

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

                          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.

                              Ok, good to know.

                              I didn't understand why this installed :

                                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.

                                      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
