Добавляем в нашу таблицу роутинга статические маршруты на VPN- и DNS-сервера:
?  ip r a 10.198.123.1 via 10.198.123.254
ip r d default
ip r
Проверка: мы должны успешно пинговать DNS- и VPN-сервера:
ping -c 3 10.198.123.254

Убеждаемся, что в файле /etc/ppp/options нет незакомментированных параметров, которыми бы система могла затереть наши настройки. Если есть - комментируем. Очищать содержимое файлов /etc/ppp/chap-secrets, /etc/ppp/pap-secrets необязательно, так как пароль у нас уже вписан в файл /etc/ppp/peers/mediana, поэтому файлы /etc/ppp/chap-secrets, /etc/ppp/pap-secrets сами использоваться не будут. Просто установим права доступа на /etc/ppp/peers/mediana:
chmod 600 /etc/ppp/peers/mediana
pppd call mediana debug nodetach
На соседнем терминале убедимся, что VPN-соединение установлено. Должен появиться сетевой интерфейс ppp0:
ip addr show или ip link show
route add default dev ppp0
