В скрипте eth по умолчанию используется ethtool, который не будет работать с ppp-ссылкой.
Также сценарий eth использует COUNTER вместо DERIVE, который будет давать вам плохие пики каждый раз, когда вы повторно подключаетесь к ppp-ссылке.
Вот мой скрипт (измените up.max, down.max на вашу пропускную способность ppp-ссылок) ...
