      Thanks for all the reply.

      To make things more simple.  I even disconnected WAN interface.

      So only the LAN interface has a cable connected to the switch.

      It is a very simple setup now, there are only 2 cables to the switch, one from Laptop, one from Pfsense LAN interface.

      LAN interface IP is 10.0.0.1 , Laptop gets it's IP from Pfsense DHCP , which is 10.0.0.50 (i've set the range from 10.0.0.50-10.0.0.100)

      Laptop can Ping 10.0.0.1 , and from Pfsense console I can also ping 10.0.0.50

      I've tried using IE and Chrome to access 10.0.0.1 but both returned Page is not available

      I've not change the default port at all

      It is very strange …

        Would you mind showing us the output of ipconfig /all or, if you are using linux, ifconfig ? Also, would you mind showing the IP and cidr of the PFSense interface? That would help a lot.. it sort of sounds like dhcp is handing out the incorrect subnet or something similar.. also, are you trying to connect to the web interface using a dns name, or the ip address directly? (I know a lot of these questions sound pointlessly simple, but they would help rule out a few things..)

        Also, have you tried setting the IP address of your laptop statically and connecting to the pfsense machine? Also, have you enabled SSH and tried connecting through ssh? If you did connect through SSH (or even could connect to ssh using telnet as a test.. ex: telnet 192.168.1.1 22) it would definitely show that you've only having issues with the web interface and not ip/tcp communication..

        Something to mention.. I've run into this issue once before actually. I ended up backing up the configs, setting it to factory defaults, loading just the firewall, nat, and alias configs and then set up wan/lan all over again… Just doing a factory reset and restoring the whole thing didn't fix the problem. To this day I've no idea what the issue could have been, as I am 1000% positive that the basic settings like IP/subnet were identical before and after. It really was beyond frustrating and annoying since I spent 5+ hours on it before I got to the point of re installing. That box is now running like a champ for a 120 user company in the transportation industry, serving out vpn connections and all. :) So don't let this discourage you...

          I had this once on a fresh install. I re-assigned interface in the console, tried to re-start the web interface in the console without success. Then I simply did a fresh install and the problem was solved…

            "LAN interface IP is 10.0.0.1"

            Why are you changing the lan IP during the install process?  When did you change it to that..  Did you restart the web from console.  I would suggest fresh install..  Let it come up on default which would be 192.168.0.1 I believe - and then try and get to the web gui.  Once you finish the setup then try changing the IP of your lan interface on pfsense to your 10 address you want.

              I agree. There have been issues with changing the LAN subnet during initial install, though I've never seen that personally. The symptoms seem to indicate the webserver is not listening/responding on the correct address/port for whatever reason. It may be possible to diagnose that but it's probably easier to re-install to the standard values and then change it later as John suggests.

                Hi Guys

                Terribly sorry for not getting back sooner, I've been away.

                I've taken some photos of my setup

                As you can see

                WAN is set to UE0 interface with IP 192.168.16.204
                LAN is set to UE1 interface with Default IP 192.168.1.1

                The RED cable is WAN connection
                The BLUE cable is LAN connection, it connects to a switch.  My notebook connects to the same switch.

                The notebook gets IP from PFSense DHCP  with the range from  192.168.1.100 - 192.168.1.150

                I can select option 7 from PFSense console to ping my Laptop.

                As you can see on my notebook screen .. I can also ping the PFSense box, but when I tried the Web Config page 192.168.1.1, I get the error message, if you look  closely to the browser tab, you can actually see the PFSense logo.

                Any idea what might have caused this?  The notebook firewall has been switched off to make things easier.

                Thanks in advance

                  And is your browser using a proxy..  And not set to bypass on local networks that would explain why it can not get to a local address..  If you have not set a proxy, then you have an infection would be my guess.

                  Fire up wireshark on the box - what does it show going on the wire..

                    Maybe I just got lost in the reading…

                    But if you are trying to reach the web gui on 10.0.0.1

                    and your lan address on pfsense is 192.168.1.1

                    You will never succeed.

                    Can you please attach a photo of the browser error you get when you try to access the web gui also?

                      You have tried https yes?

                      Since you are seeing a pfsense favicon have you ever connected to another pfSense box at that address?

                        You know - Something very basic has to be wrong because in default setup, pfsense just works.

                        I suggest a reinstall from scratch and maybe even try another computer as client.

                        Also, check your cables.

                          I have setup pfsense I don't know how many times going back to very early version 1.x - running devolpment versions, etc. etc.  Hardware and VM from everything to virtualbox, to vmware server 1, vmware server 2, esxi version 3.5 through 5.5

                          Have never seen it not just work out of the box.  So here is the thing - is anything else connected to this switch, does the switch have an IP on it or just dumb switch.

                          Validate the MAC address pfsense has for its lan interface, and the mac address your pinging.  On pfsense do a netstat do you see the web gui running?

                          [2.1.5-RELEASE][root@pfsense.local.lan]/root(7): ps -ax | grep lighty
                          46888  ??  S      0:17.64 /usr/local/sbin/lighttpd -f /var/etc/lighty-webConfigurator.conf

                          [2.1.5-RELEASE][root@pfsense.local.lan]/root(9): netstat -an | grep .80
                          tcp6      0      0 *.80                  .                    LISTEN
                          tcp4      0      0 *.80                  .                    LISTEN

                          [2.1.5-RELEASE][root@pfsense.local.lan]/root(10): ifconfig

                          vmx3f1: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
                                  options=403bb <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,tso4,tso6,vlan_hwtso>ether 00:0c:29:1e:18:ae
                                  inet 192.168.1.253 netmask 0xffffff00 broadcast 192.168.1.255

                          And again - run wireshark on the box your trying to connect to pfsense on.. What does it show?  I would really look to your browser being setup to use a proxy, and not set to bypass for local network, or infected.  You don't have anything installed on this pfsense install like squid or snort, etc.?  Its clean - and your saying its routing internet traffic - but you can not connect to even run the first setup wizard and change the pfsense password, etc.</rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,tso4,tso6,vlan_hwtso></up,broadcast,running,simplex,multicast>

                            Interesting idea that maybe something else is interfering…

                            Unplug the switch.  Plug the computer directly into the pfsense LAN with nothing else attached then give it a try.

                              ^ for all we know for his switch he is using some soho routers switch ports and it has an IP of 192.168.1.1, which you would think he would get that web gui.  But when something doesn't work that you think should be working, it takes 2 seconds to validate your actually talking to the correct something.  Have run into duplicate IPs too many times to not validate the mac.

                              I would think more likely reason is that his browser is just using some proxy..

                                Some devices do not redirect to https when you try to use http and behave like this.
                                If you had two devices trying to be 192.168.1.1 would you get ping response in both directions? Especially if one of them was the switch.

                                  no you could get answer to ping

                                  so from 192.168.1.100 I ping 192.168.1.1 but get mac of say the switch IP..  He answers.  When you ping the 100 from pfsense .1 he pings the mac of .100 and .100 send answer to the mac that asked.

                                    Hmm, yes layer 2/3 difference. The MAC would show though as you've been saying.

                                      Thanks for all the input guys, really appreciated.

                                      As suggested, I've taken out the switch, now directly connect my notebook to LAN interface (white cable , UE1 on pfsense), WAN (UE0) still the same Red Cable

                                      I followed the instructions as shown to me

                                      I can't confirm the MAC address as the J5 creator doesn't print the MAC on the unit nor the package it came with

                                      I've checked my Proxy setting to make sure

                                      I've installed Wireshark and as soon as I go to the pfsense box (192.168.1.1) I get the RED text on Black shown in Wireshark

                                        Oh I forgot to mentioned . Yes I've connected to another pfsense box to that address in the past.

                                        And .. I've also tried connecting using another Desktop PC, same results.

                                        It is a clean install, it doesn't route internet traffic yet, WAN interface is connected but I can't access internet on my notebook.

                                          Hmm, weird. Looks like the pfSense box is replying but your laptop is ignoring the replies. Perhaps.  :-\

                                          Are you able to browse other external sites? Ping external addresses? In other words is routing working?

                                          I notice your WAN interface has auto-negotiated to 10Mb which is odd but shouldn't be causing this.
