Добрый. А с другой стороны в логах что?

[mertverik]

с другой стороны тишина

[Chupaka]

А Tools -> Torch на аплинк-интерфейсе пакеты улетающие показывает?

ПК, который нормально поднимает соединение, находится за первым роутером?

[mertverik]

Да пакеты уходят. 1 микротик это сервер, второй в удаленном офисе. вот со второго микротика сессия не поднимается, хотя ПК находящиися за ним нормально поднимает ВПН
