Разрывается VPN соединение примерно через минуту

[morhad]

VPN сервер на ZyXEL Keenetic Vivo
На Ubuntu 16.04 делаю VPN-соединение, но оно разрывается не больше чем ч/з минуту с текстом "VPN соединение разорвано поскольку служба VPN была остановлена". Привожу лог с помощью нижеследующей команды. В чём проблема и как решить?

Проверил установку соединения через винду и с телефона - полет нормальный. Как тогда в Ubuntu сделать, чтобы стабильно работало? В винде и на Андроиде просто сделал соединение с параметрами по умолчанию и все. А здесь что-то не могу разобраться..
