      I'm only suggesting you delete any gateways defined on LAN in System > Routing > Gateways.

      However it should be working as it is?

          Unable to find the IP address of the server of en.wikipedia.org.

          Try:
          Checking the connection
          Checking the proxy, firewall, and DNS configuration
          Running the Windows Network Diagnostics tool

                Ok great try to ping google.com from pfSense.

                If that succeeds try to ping google.com from a client on the LAN.

                        Just run some pings from a client on the LAN.

                        The client cannot open web pages but pfSense clearly can reach external sites and can resolve DNS.
                        So either the client is being blocked (the default firewall rules should pass it though) or it cannot resolve.
                        Testing with ping should show that.

                            Try pinging from a client not from pfSense.

                            That second address doesn't appear to respond to ping so that's not a problem:

                            steve@steve-NUC9i9QNX:~$ ping giallozafferano.it
                            PING giallozafferano.it (52.17.217.40) 56(84) bytes of data.

                                Hmm, well pfSense can resolve wikipedia.org but the client cannot. Is it configured to use pfSense for DNS?

                                By default pfSense will pass it;s own interface address to use for DNS via DHCP

                                    Depends what the client is. Is it configured for DHCP?

                                    If it is t should pull the DNS info from pfSense with the DHCP lease.

                                      @stephenw10 how can I look at this information?? both to see if it is configured for DHCP?? and in case it is not configured ("If not, you need to pull DNS information from pfSense with DHCP lease")??

                                        Just about all clients will connect using dhcp by default and use the DNS information passed that way. But that can be configured manually by the user. You need to check that in Windows to be sure.

                                        You can check Status > DHCP Leases in pfSense to see if your client pulled a lease.

                                            Not v6. Just the v4 leases in Status > DHCP Leases.
