Ну... не знаю что уже делать...
По словам тех.поддержки представителя D-Link, такой трабл возможен из-за кривой прошивки самого аппарата, вроде как "проблема известная, была на 2640U/BRU/C, но в новый версиях прошивок на данные аппараты, они её устранили". По мои наблюдениям в новом аппаратном релизе С2 про неё "забыли"?

Описание:
Хочу заставить DSL-2640U/BRU/C2 поднимать pptp соединение на провайдера.
Согласно инструкции провайдера, настроил на модеме соединение MAC Encapsulation Routing (MER), после перезагрузки модем получил IP, с модема виден(пигуется) vpn сервер провайдера.
Вид таблицы маршрутов на модеме:
Destination Gateway Subnet Mask Flag Metric Service Interface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 br0
сеть_провайдера 0.0.0.0 255.255.252.0 U 0 mer_0_1_34 nas_0_1_34
0.0.0.0 роутер_сети_прова 0.0.0.0 UG 0 mer_0_1_34 nas_0_1_34

Как только включаю pptp клиента(ввод данных соединения) и перезагрузки модема, модем перестает видеть vpn сервер провайдера.
Таблица маршрутов принимает вид:
Destination Gateway Subnet Mask Flag Metric Service Interface
vpn_сервер_прова 0.0.0.0 255.255.255.255 UH 0 mer_0_1_34 nas_0_1_34
192.168.1.0 0.0.0.0 255.255.255.0 U 0 br0
сеть_провайдера 0.0.0.0 255.255.252.0 U 0 mer_0_1_34 nas_0_1_34
0.0.0.0 роутер_сети_прова 0.0.0.0 UG 0 mer_0_1_34 nas_0_1_34

а если "нету ножек, то нет и мультиков", т.е. не видит vpn сервер, то и соединение не устанавливает... в логах модема:
pptp[1622]: anon fatal[callmgr_main:pptp_callmgr.c:124]: Could not open control connection to vpn_сервер_прова

Посоветуйте, что делать!
Ждать полгода-год новой прошивки?
Какие варианты?
Заранее - спасибо!

P.S Откатил на родную, заводскую прошивку(2.0), стал поднимать PPTP.

Результат - ничего не получается.
Через MER получает модем ip адрес, вроде как модем поднимает и pptp соединение, но не работает.
Пакеты не доходят. Кривая маршрутизация на самом модеме.
Как это исправить - ХЗ.

P.S. думаю что это мое последнее оборудование от D-Link, хоть до этого и проработал у меня DSL-2540 три года без сбоев и вопросов.
С такой поддержкой... за 2 недели на форуме производителя даже ответа никакого.

У меня та же проблема, прошивка 2.03 для С2

ЗЫ
прошу дать какой-н ответ, если это кто-то читает

Тоже не работает инет через pptp клиента поверх интерфейса MER. Пингуется и vpn-сервер провайдера и шлюз, по логам вроде даже pptp поднимается - но в инет не идет. Прошивка 2.03 для С2

Для меня не понятны строчки, помеченные красным - это что за IP-адреса, подскажите? И всё-таки кто-нибудь победил 2640 с pptp или нет??
