ISP-PPOE - OpenVPN не пускает в сеть за роутером и в интернет

[AlexWalex]

Всем добрый день.

Может кто сталкивался. 

Имеем: Keenetc Titan получает интернет от провайдера через PPOE с "динамическим" IP. На Kennetic имеется доменное имя типа xxx.keentic.link и локалкой 192.168.100.0. Также поднят OpenVPN сервер 10.100.100.1, работает, клиенты подключаются без проблем, но не могут видеть сеть за роутером и не могут выходить в интернет.

Вопрос, это какая то особенность, что есть выход в сеть через PPOE, то OpenVPN не работает?

Имеется второй сервер, также на Kenetic Titan, только с традиционным подключением, и все работает без проблем. Правда IP "статический", но наверняка не в IP проблема.
