      @johnpoz 1) pi mask is 255.255.255.0
      2) Both are on a /24 mask
      3) The pi doesn't seem to have ufw installed

          If a client device cannot ping its gateway then try another client device in its place. If that device can ping its gateway then you have ruled out your router as the problem.

          If that new device still cannot ping a gateway then you can figure a configuration issue on your router.

            And is the gateway correct?

              @bgksdfol It can ping its gateway, but not the gateway of the other lan port on the router

                @johnpoz It is 0.0.0.0 so I am going to assume not

                  That would default destination - but the IP, ie the gateway is what when you do a route -n

                  See my above screenshot from my pi..

                  My gateway is 192.168.3.253, which is pfsense IP on that vlan. if you don't your gateway pointing to pfsense IP on this network, then no your never going to ping anything off its network, nor would you be able to answer anything coming from another network.

                    @johnpoz The Destination is 40.0
                    Gateway is 0.0.0.0
                    mask is 255.255.255.0

                    How do I correct the gateway?

                      @bgksdfol why don't you just set the pi to get its IP via dhcp?

                      Pretty sure that is the default, if you want your pi to always have the same IP - you can just easy set a reservation in pfsense dhcp server. Is that what you did and you put in some gateway there?

                        @johnpoz So the pi is getting a static ip from the OPT dhcp server. I am not sure how to set a gateway in the DHCP server

                          @bgksdfol so you setup a reservation there.

                          so for example here is reservation for my pi

                          gateway.jpg

                          The gateway should be left black, so it defaults to telling the client to use the pfsense IP on that network as its gateway. Did you put something in there? like 40.0 ?

                              @bgksdfol well then something wrong with your pi - if you plug in a laptop or pc to that network do you get the correct gateway?

                              Can we see the output of your route -n?

                              destination of 0.0.0.0 is correct for default route.. That should have gateway pointing to the IP address of pfsense on this network, which I take is x.x.40.1 (btw there is zero reason to hid rfc1918 space..

                              If your gateway says its 40.0 then that is wrong, but I don't see how pfsense would of handed that out?? You could of maybe overridden the dhcp settings on the pi?

                              Notice my output from above - gateway of 0.0.0.0 is correct for the local network, in my case 192.168.3.0..

                              iproute.jpg

                              default route (destination) 0.0.0.0 points to my pfsense IP 192.168.3.253 on this network.

                              the route to get to the network my pi is on 192.168.3.0/24 (see the mask 255.255.255.0) would 0.0.0.0

                                  I read recently a post here, where a Pi didn't obey the gateway from the DHCP server.
                                  Try to set it static.
                                  Found this: https://raspberrypi.stackexchange.com/questions/57655/fixing-gateway-on-dhcp-connection-raspberry-raspbian

                                    @bgksdfol ah - yeah never going anywhere without a default gateway.. Never had any issues with my pi's have run many of them over the years currently 2 of them running..

                                    What OS are you running on them?

                                          You didn't have a real route before, you only had your the own subnet connection on the Pi.

                                          Can you ping the other pfSense interface IP now? And also the devices in the other subnet?

                                            @bgksdfol you should be able to manually add the default route with that command given in the link.

                                            Taking a look here
                                            https://www.raspberrypi.com/software/operating-systems/

                                            You should be able to run the 32bit version of bullseye on any pi.. now I am trying to remember why I didn't update to bullseye when it came out??? I think it had something to do with the gps ntp server running on one of them.. But why didn't I update the other one??

                                            Hmmm - guess I got something to do tmrw ;) Maybe next weekend, I don't think I have any spare sds laying around.. That is why prob didn't do it, and just never got around to ordering them.. I got them setup exactly how I like, so like having a backup on sd so can just put the backup sd in and get back to exactly how I was..
