      just an idea
      it would be worthwhile to look at and compare these:

      Windows: https://docs.microsoft.com/en-us/previous-versions//cc977482(v=technet.10)?redirectedfrom=MSDN

      Linux: /etc/resolv.conf

      search domain.net
      option timeout:1
      nameserver 1.1.1.1
      nameserver 2.2.2.2
      nameserver 3.3.3.3

      or something like that

      Cats bury it so they can't see it!

        I removed the localhost from the general setting and these are the results

        @DaddyGo It was a good suggestion, but unfortunately /etc/resolv.conf is managed by systemd-resolved who is used by netplan /etc/netplan/*.yaml

          Interesting, well the two DNS servers seem to be responding better now. That could also be because they are caching.

          How is Ubuntu getting its interface settings? Is it statically assigned in Ubuntu or is it set to automatic (DHCP)? There were no leases in your DHCP list.

            I assigned static ip through /etc/netplan/01-network-manager-all.yaml

            8289bd18-79be-4859-a103-cc2f027aab86-image.png

            Everything seems good to me....

            Edit, maybe an non relevant information, i can not ping the other vms in the dmz network. But my other vms can ping my ubuntu vm. Could it be something to do with routing ?

              Try running a packet capture on the DMZ of pfSense.
              Diagnostics/ Packet Capture
              Select DMZ, then in Count enter a very high value such as 10000. You can enter 0 but don't forget to stop the capture manually otherwise it will run a continuous capture and it can become a problem.

              Download the capture data to wireshark and check for DNS info.

              Dumb question, but have you tried to ping 8.8.8.8 from ubuntu? Does that work or is that failing as well?

                Nope doesn't work because its blocked by the school.

                I'll try the packet in a few minutes

                  ICMP is blocked or google DNS server specifically is blocked?

                      So apparently my ubuntu machine does not send any dns request :

                        That's not good. Is it even able to talk to pfSense at all? Can you ping pfSense (192.168.1.1) from Ubuntu?

                            It can't ping Windows because by default Windows does not respond to ping. That has to be manually enabled in Windows. It is responding to pfSense though. So at least there is some sign of life there.

                                lol don't touch it. You have a number of things which don't make sense. Like for instance the ping to pfSense is taking on average 600ms. In reality it should be more like 6ms. You have two extra zeros of delay. That's not good.

                                  Apparently even this is fixed. :

                                  192.168.1.1 is my gateway to pfsense and 192.168.0.50 is pfsense ip..

                                  I really hope it will stay working as i need it crossfingers

                                  Many thanks for your help guys!

                                    you donโ€™t have to disable it all, just use this ๐Ÿ˜‰

                                    netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow
