Ставим OpenVPN на OpenWRT для VPNKI.ru

Иии? прямо п.5 не получается?

Посмотрел по логам - соединения были успешны, но... они отключаются каждые 2 минуты и это странно.

Вот выдержка из лога:

В сухом остатке
- вы уверены, что вы вставили в настройки соединения тот конфиг, который скачали с сервера (без шифрования) ?
- возможно проблема в размере MTU - на сервере link-mtu 1525, а на клиенте link-mtu 1557. Можно попробовать изменить размер MTU в файле конфигурации клиента, поставить link-mtu 1525 и перезапустить OpenWRT
