      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.
