есть 1811
настроена на 2 канала и нат вовнутрь.
один канал статика (основной), второй - PPPOE
как указать кошке что собственно основной первый и с него спрыгивать только при падении онного и возврат сразу по появлении, ато он любой выбирает как захочет

192.168.0.1 - шлюз PPPOE
второй - шлюз статики
