      @hoandco if your internet connection is high latency, wireless, satellite etc.. pfsense since the responses to its ping monitoring are slow - its going to think the gateway is down.

      You need to adjust the monitoring of that gateway to reflect your high latency so that pfsense knows the gateway is actually up, if pfsense thinks the gateway is down it will not route traffic over it.

        @hoandco said in No LAN internet:

        How do you suggest I adjust this.

        In the gateway config. System > Routing > Gateways. Edit the gateway, look in the advanced config section.

          That worked. I set it to 700-900.
          Now I still don't have internet on lan PC's.
          Is this because there is no upstream gateway added?

            It could be. Did you check for a default route like I said above?

            Make sure there is a default v4 gateway set.

            Edit: I see there was previously a default route set though.

            Try to ping, say, 1.1.1.1 from the client. What error is shown?

                  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 ??

                      Did you the ping 1.1.1.1 in terminal on lan connected pc.
                      It is connected to the pfsense pc through an unmanaged tp link 16 port switch.

                                  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.

                                            I tried the gateway on the LAN but it it did not work

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