L2TP / IPSec от Windows 7 до ASA 5520

9

Я пытаюсь настроить L2TP / IPSec на нашем ASA5520 для поддержки дополнительного случая для одного из наших разработчиков. Подсистема Windows VPN, по-видимому, сохраняет cookie Kerberos или NTLM для входа в систему при использовании встроенной подсистемы vpn, а клиент Cisco VPN и клиент AnyConnect этого не делают.

Когда я пытаюсь подключиться к VPN через Windows 7, происходит сбой подключения:

В частности, я думаю, что эта ошибка имеет значение:

Несоответствующие типы атрибутов для класса Режим инкапсуляции: Rcv'd: UDP Transport Cfg'd: UDP Tunnel (NAT-T)

Отладка из драйверов шифрования, кажется, не очень помогает; ниже приводится уровень 127 isakmp и уровень 100 ipsec:

Очевидно, что несоответствие фазы 2 обычно устраняется путем изменения предложений, но, к сожалению, похоже, что Windows 7 вообще не позволяет вам портить настройки предложения. Нет никакого способа включить NAT-T явно в конфигурации Win7.

Итак, мой вопрос таков: моя конфигурация винтовая? У кого-нибудь есть L2TP, работающий должным образом с Windows 7 на ASA с 8.4 загруженным?

Этап 1 завершается ошибкой, потому что вы не настроили клиента для использования группы 2 Диффи-Хелмана. И все же сервер требует этого.

У меня IPSEC работает в режиме «локальной сети» между Windows 7 и ASA с 8,3 (2) 13 (сертифицирован FIPS).

Я совершенно уверен, что вы правы в отношении ошибки - если он не может договориться о SA, вы попадаете.

Я бы попробовал избавиться от "NAT Traversal". Конечно, вы можете застрять при попытке перейти через NAT, в этом случае это может потребоваться. Но это точно выглядит как причина вашей проблемы.

Я предполагаю, что ваш другой вариант - выяснить, как заставить Windows 7 выполнять тип SA nat-traversal. Вы можете попытаться возиться с netsh advfirewall consecокнами.

Вот ссылка на нее, которую я добавил в закладки. http://technet.microsoft.com/en-us/library/dd736198(v=ws.10).aspx .

Одно замечание - в документации Windows много говорится о том, как важно регулярно менять соединение. Однако, если вы перепрограммируете слишком часто, ASA берет дамп и разрывает соединение. Убедитесь, что вы не повторяете клавишу чаще, чем каждые 2 минуты. При использовании рекомендованного MS значения количества байтов для повторного нажатия стало меньше 2 минут.

Когда мы открыли службу поддержки, M $ не смог дать никаких реальных причин для их рекомендации. Они прислали нам большой жирный счет.

Для тех, кто приезжает сюда:

Если статические и динамические одноранговые узлы настроены на одной и той же криптографической карте, порядок записей криптографической карты очень важен. Порядковый номер записи динамической криптографической карты должен быть больше, чем все остальные записи статической криптографической карты.
