Провайдер изменил условия подключения и вместо Static теперь 4 подключения PPPoE (4 разных логина/пассворда). Т.к. локальная сеть питается инетом через меня, то надо держать все 4.
По одному поднимаю без проблем (уверен, что можно подключать несколько одновременно).
В процессе экспериментов поднять 2 соединения не получилось

только у ng1 IP отсутствует.

судя по вебморде mpd - все хорошо (ng0 и ng1 неотличаются и во вкладках тоже)

Курить маны уже не помогает, а в инете ничего найти не удалось.
Пользователи уже мозк склевали - инет, оказывается, хороший наркотик ;)
