    And that is why pfSense does not work.

    By default PFSense sets it's LAN network to the 192.168.1.* range, you cannot have that range on both the LAN and WAN interfaces.

    You need to go back to the shell menu of pfSense,Option 2, and change the LAN address and DHCP range to 192.168.2.*

        hey despite of changing pfsense LAN ip to 192.168.2.* i cant access it in web gui (pfsense) from the system comming under cisco switch connection

        cable modem (192.168.1.251)> pfsense (192.168.2.1)> cisco switch(smart switch) > other system.(192.168.1.*)

        from above i am unable to access pfsense web gui from systems under cisso switch(managed one).

          I said, connect directly to pfSense from your Laptop, where did I say to go via the Cisco switch?

          Can you connect to pfSense when connected directly from the LAN port of pfSense to your Laptop, YES OR NO?

            yes , i can directly connect pfsense with LAN port of laptop i get DNS server as 192.168.2.1 and IP V4 of laptop as 192.168.2.2 , Here 192.168.2.1 is the LAN ip assigned in shell prompt of pfsense .

              Good. Now connect the WAN port of pfSense to the ISP router.

                  OK, leave the WAN connected, and go into the pfSense Web interface, What does it show as the IP address of the WAN interface?

                      Does it show the WAN interface as UP? (green arrow)

                      Can we see a screenshot from Status > Interfaces.

                          Dude…why are you opening multiply thread on the same exact issue...that's a big turn off!

                          Onto the subject at hand...sounds to me some conflict going on with your cable modem and might need to be in bridge mode.

                              A screenshot of the WAN from Status > Interfaces would be very helpful here. Please try to get that.

                              If the interface shows the red 'down' arrow though that implies it's not even connected. I would look for a link issue, perhaps a bad cable or speed/duplex mismatch. That assumes your WAN is Ethernet directly though, if it's PPP of some sort there may be other issues. The screenshot would tell us all that.

                                I see in fact you did post a screenshot in one of the other threads you opened. I re-attached it here.

                                That shows what looks to be a working connection. The WAN is linked, UP and has a valid IP.

                                It seems like you are trying to put the cable router in modem mode to bridge the PPP connection yes?

                                    If it's showing a private IP on the WAN like in that screenshot it's because the ISP supplied modem/router is not passing it through. Instead is it running a dhcp server and giving pfSense a lease from that.

                                    If it's a PPPoE connection you will need to configure the 'modem' to run is modem or bridge mode and then configure the PPPoE connection on the pfSense WAN.

                                        can please share me how to configure PPPoE configuration steps

                                        Your device that is hooked up to your cable/phoneline/Coax incoming wire should be put into pure "modem" mode. In that case it just 'translates' info from one line - the incoming connection, to packets that flow over an Ethernet cable to pfSense.
                                        This Ethernet cable should be put into the WAN interface. PPPOE should be activated on this WAN (pfSense)  interface, and you probably have to enter some credentials (logion + password : transmitted to you by your ISP - this same info is present now in your router device, so it can enable the conenction).

                                        Everything depends on the instructions given to you by your ISP (their support web site, FAQ, etc)  - you haven't said anything about that part, so we don't know nothing about that.

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