Настройки и конфигурация VPN (PPTP) в Windows 2000

Выполните следующие действия:

Выберите Пуск > Настройки > Сеть и удаленный доступ к сети > Новое подключение.
В появившемся окне мастера подключений выберите Тип сетевого подключения, затем выберите Подключиться к частной сети через Интернет.
Выберите Набрать номер для следующего предварительного подключения.
В поле Host или IP Address укажите адрес места назначения и нажмите Далее.
Выберите Пуск > Настройки > Сеть и удаленный доступ к сети, затем выберите соединение, которое только что было настроено.
При появлении следующего окна выберите Свойства > Безопасность для настройки параметров.
Выберите Дополнительно (настройки заказчика), затем выберите Настройки и укажите соответствующие типы шифрования (пункт «Шифрование данных») и аутентификации (разрешите эти протоколы).
В разделе «Сеть» (тип вызываемого VPN-сервера) выберите PPTP и нажмите OK.
Появится окно проверки имени пользователя и пароля.
Появится сообщение о выполнении регистрации компьютера в сети.
Появится окно «Свойства подключения».
В следующих окнах отображается состояние подключения.

Проверка

В данном разделе содержатся сведения для проверки работы текущей конфигурации.

Средство Output Interpreter (OIT) (только для зарегистрированных клиентов) поддерживает определенные команды show. Посредством OIT можно анализировать выходные данные команд show.

show debug – отображает команды debug, разрешенные в данный момент, для диагностики
show user – отображает список и состояние пользователей, работающих в системе в данный момент
show ip route connected – отображает текущее состояние таблицы маршрутизации
show vpdn – отображает информацию об активном туннеле с протоколом пересылки 2-го уровня (L2F) и идентификаторы сообщений в виртуальной частной коммутируемой сети (VPDN)

Ниже приведен пример выходных данных команды show debug.

2621#show debug
PPP:
  PPP authentication debugging is on
  PPP protocol negotiation debugging is on


VPN:
  VPDN events debugging is on

Выходные данные отладки с начальной настройкой PPTP имеют следующий вид.
