        Then :

        0326827f-c9b2-4af8-a684-900c39c794e7-image.png

        What is the OS ?
        And what is the gateway ?

        Do you have wifi activated and the cable to pfSense connected at the same time ? If so, remove wifi for the moment.

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

                        Are you sure that your PC 192.168.55.1 got its DHCP inform from pfSense ?
                        You didn't change anything on the DHCP server (LAN) page ?
                        Check the DHCP server log page, do you see your PC doing DHCP request and pfSense DHCP answering ?
                        Your PC should use 192.168.55.1 for a gateway and DNS.

                        It looks like this
                        https://serverfault.com/questions/402023/why-do-icmp-redirect-host-happen

                        is happening because pfSense 'thinks' there is another gateway on the LAN 192.168.55.0/24 ....
                        I never saw that kind of messages ...

                          Did the IP get changed from the 182 to 192 on pfsense? Did you set a gateway on this interface? If you did then pfsense thinks its a wan IP.. You do not set a gateway on the lan side interfaces of pfsense.

                            Thanks Yes I did change the IP address to 192.
                            However I still cannot connect to the internet on a Lan connected pc.

                              @hoandco did you set a gateway on this interface - you do not set a gateway on a lan side interface.

                              lan.jpg

                              Are your clients actually using that as their gateway, or do they still try to talk to the old 182 address?

                              What is the routing table on pfsense?

                              routes.jpg

                              Notice my default route is out the wan.. Routes for other networks that are local, are direct, etc.

                                I tried the gateway on the LAN but it it did not work So I changed it back.
                                This is on dedicated pc with 2 port intel card.
                                The gateway is connected online as you will see.
                                The LAN rules appear to be working.
                                However I can't get internet on my pc or laptop connected to the LAN.

                                  There is NO gateway set on a lan side interface... If you tried that no then it wouldn't work..

                                          Ok so am I correctly reading that a client on LAN can ping 8.8.8.8 but not 1.1.1.1?

                                          And that when you try to ping 1.1.1.1 you see at the LAN client:

                                          Host(New nexthop: 0.0.0.0)
                                          From 192.168.55.1: icmp_seq=34 Redirect Host(New nexthop: 0.0.0.0)
                                          

                                          That implies you have a routing issue on pfSense. Check the routing table again.

                                            So just to be sure.
                                            If ping 8.8.8.8 from pfsense menu it works. If I use terminal on the same pc with pfsense app open it works. If I ping 1.1.1.1 in terminal on the same pc it shows what I sent.
                                            So what can be wrong with the routing table? How do I check it? What should it show.
