Настраиваю vpn соединение по этой инструкции -
https://www.rapidvpn.com/setup-vpn-l2tp-mint
Устанавливаю vpn соединение с моим сервером. Соединение устанавливается, но пинги не ходят, страницы в интернете не открываются, доступа к локальной сети за серваком - нет. Как буд-то возникают проблемы с роутингом пакетов после того, как получаю конфигурацию по dhcp от удаленного сервака. Через примерно секунд 20 соединение разрывается.
Сразу оговорюсь, подобное соединение с тем же серваком из под Windows или MacOS работает без проблем. Подключение к инету менять пробовал. Проблема не в провайдере. Плагин xl2tpd в нетворк-менеджере подменял на kl2tpd. Проблема не уходит. До переустановки линукса, vpn клиент работал.
Что не так сконфигурировано на Linux Mint? Логи с клиента прилагаются
