Имеем партию 2540U C2 (P/N RSL2540UEBRU2C2E). Последняя прошивка. (ru_2.02)

Режим WAN - MER со статическим адресом. Шлюз указан руками (IP-адрес)

Далее выход в интернет по PPTP. Но, при настройке PPTP клиента, модем добавляет маршрут на ВПН сервер на интерфейс WAN и шлюз 0.0.0.0

Соответственно в логах получаем: no route to host

Добавление статических маршрутов не помогает.

Как быть?

такая же проблема у 2540BRU/C с прошивками 1.23. и 1.24

pptp подымается только на прошивке 1.22

Если в BRU/C на 1.23 и 1.24 и в BRU/C2 на 2.02 вручную убить роут через телнет, то pptp все ранво не подключается. Различий в конфигах между прошивками 1.22 1.23 и 1.24 не нашел.

Вот лог:

Интересно, у DLINK ТП вообще есть?

Речь идет не о 1-2 модемах, а о партихя в несколько килоштук

Приведите, пожалуйста, настройки со страницы Advanced Setup -> PPTP. А также таблицу маршрутизации модема.
PPTP-сервер находится в подлежащей сети?

Схема и скрины. При прошивке 1.22 на С1 все работает (не считая что PPTP pass-throw не работает)

В прошивках 1.24 в С1 и 2.02 в С2 не работает.
Если удаляю роут, то pptp все ранво не работает (см лог)

UP!

Все еще актуально. Старая партия закончилась. Что брать новое?

up/
ответа так и не получили.

Подтверждаю проблему с некорректной таблицей маршрутизации. Штаб-квартира работает над решением проблемы.

Для модема DSL-2640U/BRU/C2.
Попробуйте, пожалуйста, эту бета-версию прошивки.
Таблица маршрутизации исправлена. Если pptp-туннель всё равно не получится установить, то снимите дамп пакетов со стороны сервера.
ftp://ftp.dlink.ru/pub/ADSL/DSL-2640U_B ... x_beta.img

Для других моделей прошивка появится в ближайшее время.

Столкнулся с такой же проблемой, убил пару дней на настройку и танцы. Покупая один из самых распространенных модемов не было мысли о таких "фичах", а брал изходя из наличия PPTP.



Попробовал, в логе ошибки пропали, но интернет не появился. Как делать дамп не в курсе.

Новые прошивки для всей серии:

DSL-2640U/BRU/C2
ftp://ftp.dlink.ru/pub/ADSL/DSL-2640U_B ... 100804.zip

DSL-2540U/BRU/C2
ftp://ftp.dlink.ru/pub/ADSL/DSL-2540U_B ... 100804.zip

DSL-2600U/BRU/C2
ftp://ftp.dlink.ru/pub/ADSL/DSL-2600U_B ... 100804.zip

Если проблемы с подключением VPN-серверу останутся, пожалуйста, приведите полный лог модема предварительно включив его и выставив уровень логирования Debuging.

DSL-2540 BRU C2 F/W ver.: 2.03. Проблемы с подключением VPN-серверу остались.

PPTP-клиент не может прочесть пакет от сервера.
Причин может быть много, необходимо снять дамп пакетов с PPTP-сервера и анализировать.
Также необходимо проверить параметры сжатия/шифрования.

Отправили Вам мылом

Как видно из Вашего дампа пакетов, PPTP-сервер предлагает тип аутентификации MSCHAPv2. Данный протокол не поддерживается модемом из-за ограничений ОЗУ. Поэтому модем не шлёт ответ на PPP LCP Configuration Ack.
Попробуйте установить тип аутентификации на сервере PAP или CHAP.
