        As John mentioned you'll only see IP addresses.

        Create an outbound firewall rule allowing port 80 & 443 outbound, set it to log and place it right at the top of the rule list.

        They appear here :-

        Status -> System Logs -> Firewall

          Please be patient. How do I create an outbound rule ? Never done that before.

            Firewal -> Rules -> LAN

            Add

            Create two rules, one using port 80 as a destination, one using port 443 and tick Log packets that are handled by this rule.

            Drag the two rules to the top and hit save.

                don't worry about the top rule as it's only http to the firewall that interface.

                http and https will match your new rules rather than your pfblocker rules you might want to move them a bit lower.

                  Also I can use Google's imap which is on port 993. Shouldnt that be blocked now ? I mean only 80 and 443 are allowed.

                    the rules just allow and log you've not blocked anything.

                    they read from the top down.

                        Nevermind you did put the rule on the lan side..

                        Unless your using something like QUIC or SPDY your never going to see UDP on 80/443 for websites.

                          if you want great granular view pftop or pflowd.  You can find many free netflow collectors.  This captures everything.  I suggest at least trying it and you will understand.
