    Yes, it should pass the ISP supplied IP to the pfSense WAN. Or at least that's what I would expect to see.

        Ok so DHCP was enabled the whole time but I went to my ETHERNET settings (I think this meaning ethernet WAN port) and set to LAN Only and now its working.

        However, the device is still reachable via the private ip. This does make me wonder if this is a true transparent bridge. I dont like this.

          Are you seeing the public IP passed to the pfSense WAN?

            @stephenw10 yes, after making sure the LAN DHCP server was enabled and setting the WAN/LAN mode the LAN Only, now pfSense is getting a my static private IP, however somehow I am still able to ping the router @ 192.168.1.1 with no gateways and static routes in place

              @deanfourie said in Huawei B818 Bridged Mode:

              pfSense is getting a my static private IP,

              You mean public IP?

              Well the LTE router is in the default route so it will be able to respond as long as it has a route back to the pfSense WAN IP, which it apparently does.

                @stephenw10 sorry Public IP, I should go back to bed.

                But in bridged mode, I would not expect there to be a route.

                After all, it should be a transparent device no?

                  Check the MAC addresses. Does the 192.168.1.1 IP appear to use the same MAC as the gateway?

                      I mean the upstream gateway that pfSense is using on the WAN side. Which I imagine must be one of those 163. IPs? And I assume that's inside the WAN subnet?

                      You would have to open a request to 192.168.1.1 and if it's local you might see it.

                      However given that you can see at least 4 IP in the 163.47.0 subnet they might simply be routing that to you. In which case 192.168.1.1 might just be added as a second IP on the router. pfSense would not see that as local but can still reach it via the default route.

                        @stephenw10 but why on 3 different subnets, I'm assuming they are /24 and there is a .0 .1 and .2 subnet

                          What size WAN subnet does it give you?

                          The fact you are seeing those IPs in the ARP table implies they are sending traffic to you. So probably broadcasts.

                            @stephenw10 so why would I be receiving traffic on another public IP other then my own static public IP?

                            Is this normal?

                                    If it's in the same subnet then you would see any broadcast traffic from those IPs, yes.

                                    I have no idea yet if your WAN IP is in that subnet or not if one of them is the gateway you are being passed by DHCP. I would imagine they are.

                                      Actually is looks like it is. What subnet mask is it given?

                                        @stephenw10 no, my WAN interface on pfSense is given my public static IP, not a private.

                                          Those are public IPs. The IP you are logged into the forum with is also in that range.

                                          What subnet mask is is giving pfSense on the WAN?
