Subject : pppoe - ppp (LCP) troubles
--------------------------------------------------------------------------------
Hello, All!
Есть 1721, которая должна поднимать 2 клиентские pppoe сессии. До
провайдера - радиоэзернетом, но не суть, т.к. до определенного момента
все работало нормально. Однажды провайдер поменял сетку (ип-адреса) - ну
казалось бы, что в этом такого - для клиентов должно быть все прозрачно.
Ан нет, поднятие сессии может продолжаться больше часа - таймауты на
фазе LCP. Причем не важно, одна сессия пытается подняться или обе сразу.
Конфиг и дебаги ниже

То есть не доходит даже до аутентификации. Самое обидное, что
подставляешь писюк с RASPPPOE - все проходит на ура. Да и раньше ведь
работало...
Да, и еще:
