Проблема с подключением vpn

А как ты подключаешься?

Какие команды вводишь?

Сравните в /var/log/syslog логи от NetworkManager от удачного подключения и от неудачного.

Нужно смотреть логи: /var/log/daemon.log /var/log/syslog

Немного попыток угадать:

Либо в if-up прописаны маршруты, либо это днс. Но по логам будет проще понять.

А как ты подключаешься?

Какие команды вводишь?

Подключаюсь через графическое меню в системном лотке, команд не ввожу.

(Прошу прощения за много букв, но тег «cut» почему-то не хочет работать)

На всякий случай, сохранил также логи NetworkManager для подключения к локальной сети - как при входе в систему, так и после переподключения.
