        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.

                    Ok maybe you disabled IPv4 DHCP when you change the LAN IP.

                    Go to Services > DHCP Server > LAN and make sure it's enabled.

                      Services > DHCP Server > LAN
                      Enable - Enable DHCP server on the LAN interface (yes)
                      Is this feature already enabled or is it something else I need to look at?

                        Yes it should be enabled by default. Check Status > Services.

                            Hmm, seems very odd that there's no DHCL leases shown. I don't think I've ever seen that.

                            What IP address is your Windows client using?

                            Did you set that statically? If not it must have pulled it via DHCP.

                                Yes ipconfig /allshould show it. Though it's been years since I ran Windows!

                                  @stephenw10 ok,
                                  connection-specific dns suffix: brokenboy.local
                                  dhcp enabled: yes
                                  automatic configuration enabled: yes
                                  ipv5 address local to the link: xxxxxx (preferred)
                                  ipv4 address: 192.168.100.xx(preferred)
                                  lease obtained at 10 am
                                  lease scanned at 5pm
                                  default gateway, dhcp server, dns server are the same 192.168.100.x

                                  lan cards, local network connection are disconnected (obviously, because the pc is not connected to the switch)

                                    Ok that's good.

                                    I assume the client still cannot resolve wikipedia.org?

                                    Go to Diag > DNS Lookup in pfSense and check wikipedia.org there. Make sure all defined DNS servers are able to resolve it.

                                        Hmm, that all looks good then. Is the client still unable to resolve it?

                                            pfSense is showing that localhost (127.0.0.1) can resolve it. That's the local DNS resolver, Unbound.

                                            LAN side clients should be using that to resolve against. The fact your client cannot implies it isn't using pfSense.

                                            Can you test with a different client?
