      Заметил что с недавнего времени squid на моем шлюзе перестал блокировать сайты из черного списка, если вручную прописать прокси в браузере то все нормально. Куда копать подскажите? Обновление никакое не ставил.

            @max5775 Попробуйте выставить Outgoing Network Interface в Auto:

              @viktor_g не дало эффекта. Для прозрачного режима на firewall нужно что-то открывать? У меня по дефолту - все запрещено и открыты только выборочные адреса и порты. Поднял чистый pfsense и протестировал - все работало до определенного момента. Когда начал править firewall, получил тоже самое - в прозрачном режиме (Без Прокси в настройках firefox) ничего не блокирует. К сожалению на каком этапе все крашится пока не выяснил.
              Вот что на порту 3129, т.е ничего не приходит.

              sockstat | grep 3129

                @max5775 Какая версия pfSense и Squid package?
                покажите /tmp/rules.debug (с включенным прозрачным режимом)

                  @viktor_g PfSense-2.5.1, Squid-4.45_5.
                  Вывод rules.debug слишком конфиденциален, могу в личку скинуть?

                    Можно
                    Ещё хорошо бы обновить pfSense до 2.5.2

                        Разобрались

                        совет такой - используйте алиасы в "Bypass Proxy for These Source/Destination IPs", а не перечень IP/доменов
