      You should at least be able to ping all interfaces of pfSense with the allow any rules.
      If you only can ping the the interface IP, which the device is connected to, I would suspect that there is something wrong with the network settings, either on the device or on pfSense.

        @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?

                                      Mine are both running

                                            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?
