Добрый день товарищи форумчане, нуждаюсь в помощи, а именно по встроенному в freebsd демону pppoed, который перестал пускать клиентов, не принимает протоколы шифрования.

Клиенты под win xp, в один момент перестали работать все, ошибка 691, в логах ругань на шифрование и маршрут, игра с выбором протокола на сервере\клиенте - безуспешна, пароль\логин верные.
Прошу помощи или наставления на путь истинный.
