          @Spectrum do you suggest to delete this option in the lan network (re0)?

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

            However it should be working as it is?

                              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

                                      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")??
