      you should filter on the IP your trying to go too.. this 46.105.102.174

      Or its going to only log everything - default to only 100 packets. So quite possible you miss what your looking for.

      Also you can then download that in wireshark and get more details.. If there is an answer, was it RST or FIN, etc.

        I still see only

        11:31:06.926814 IP WAN_IP.1089 > 46.105.102.174.80: tcp 0
        

        and assuming that I understood you correctly for "If there is an answer, was it RST or FIN, etc." i see in pfTop:

        pfTop: Up State 1-8/8 (571), View: default, Order: bytes
        PR        DIR SRC                           DEST                                   STATE                AGE       EXP     PKTS    BYTES
        tcp       In  192.168.90.8:56162            46.105.102.174:443            ESTABLISHED:FIN_WAIT_2   00:08:17  00:10:08     3745  3625782
        tcp       Out WAN_IP:14382          46.105.102.174:443             FIN_WAIT_2:ESTABLISHED  00:08:17  00:10:08     3745  3625782
        tcp       In  192.168.90.3:32870            46.105.102.174:443                 CLOSED:SYN_SENT     00:00:37  00:00:24        6      360
        

        Maybe using Packet Capture incorrectly ?!

          @chudak Why is it going to port 80 when I asked you to go to https? Set your packet capture to WAN and host address 46.105.102.174 then start it, then go to your browser and try the address https://www.addic7ed.com and don't forget the S.

              And you get no answer.. from that last sniff.. So pfsense is NOT blocking anything..

                I agreed with that !

                The question after that was what is blocking ?

                I checked on a remote ubuntu box and it works fine. Could it be my ISP +/- upstream DNS servers ?

                  @chudak I had a guy last week with this same problem. It turned out his IP address was blocked for too many bad logins. He had other IPs available and when he switched to another, the remote site responded and worked. Do you have a VPN you could try going there through?

                    That maybe a different issue.
                    I can use a remote system (not on my net) and can login from it.
                    Also in my case I can't even get to a login page...

                      What is upstream of your pfsense? Just your ISP? Could be connectivity issue with that site from your isp, ie peering. Or the site themselves might of blocked your IP, etc.

                      DNS is not involved once you resolve the fqdn.. If you got the correct IP when you resolved, then dns is no longer in the picture.. I show that resolving to the same IP.

                      And works just fine here as far as connectivity is connected, get redirect to 443 when hit it on 80 via a 301 and then index is downloaded

                        I have Sonic fiber ISP
                        Good point about DNS - withdrawn

                        Dunno, flaky, we will see

                        Thanks guys @johnpoz @KOM for walking me thru Packet Capture
                        I don's use too often.

                        Although this case maybe not had been a good example

                          Well, that would make sense if your WAN address is blocked. The remote system isn't blocked.

                          Also in my case I can't even get to a login page...

                          In the other guys' case, they were blocking his IP at the external firewall so he didn't get a login page either.

                            That's interesting...
                            Maybe then it's my case.

                            Do you know by chance how many say bad requests did it take to get it blocked ? and how long was it blocked ?

                              @chudak That depends entirely on whatever software they're using to monitor that. I have no idea. It could be fail2ban or something else. Unless you are using a user account to login to that website, his case would not apply to you. Perhaps you're blocked for another reason? We haven't yet established that you're being blocked, only that they do not respond to you. If you have a VPN (seriously, get one they're like $5/month) you could go there via your tunnel and see if it just works. Contact the site's host and ask them if you're blocked.

                                Forgot to mention that it did work via VPN tunnel
