      imho probably your ISP, ping your isp gateway and see if you have the same problem, if it work without problem do a traceroute and ping every single hop until you find what is timing out, after that call your ISP
      also check if all your cable are in good condition

        I tried without pfSense directly connected to WAN VLAN, everything working fine without any problem which means it's pfSense problem 100%

          esxcli network nic tso set --enable=0 -n vmnic0
          esxcli network nic cso set --enable=0 -n vmnic0
          ?
          i'm pretty sure it's not a pfsense problem
          try to use another physical network interface card to connect the virtual switch to the physical switch to eliminate physical problems.

          esxi version? ESXi 6.0 is known to have host loses network connectivity randomly
          check /var/log/vmkernel.log file, if there is evidence of transmit timeouts

                    did you set traffic shaping or load balancing on the vswitch ?

                        i'm tring to mess as much as i can with my vm but i'm unable to reproduce it
                        can you do a test with pfsense 2.5.0-devel ?
                        also i found this about the vmx driver
                        https://www.freebsd.org/cgi/man.cgi?query=vmx&sektion=4
                        ethernet0.virtualDev="vmxnet3" i have it inside the virtual machine configuration and
                        The hw.pci.honor_msi_blacklist tunable must be disabled to enable MSI-X support.
                        i have it set on my
                        /boot/loader.conf.local

                        hw.pci.honor_msi_blacklist="0"

                        also i found this but idk if it's still relevant

                          I have a bunch of pfsense instances running in ESXi. No issues. All 2.4.4-p3 and 2.4.5-RC.

                            Yeah I don't think this problem is pfSense related.
                            Can you spin up two more VMs for testing? One with vanilla FreeBSD 11.2 and another with Linux or Windows. Check if the timeouts happen in one or both test VMs.

                                i told you 4 days ago to disable cso "esxcli network nic cso set --enable=0 -n vmnic0"
                                but i forgot to tell you to disable it from the pfsense gui

                                    Awesome. I poked around on a few of mine and didn't find any with that enabled. Mostly Dell hardware here. Good find.
