Привет, я настроил на RouterBOARD 450G (версия RouterOS 5.26) правила для изменения IP и MAC адресов источника мультимедийных кадров. Но я вижу потерю пакетов между входным и выходным интерфейсами в таблице Overall Stats. Например: для интерфейса ether4-in-ch2, где приходит мультимедиа: Rx(1024-1528) = 35200. Для интерфейса ether3-out-ch2, Tx(1024-1528) = 35032. Тест проведен с известным потоком. Скорость 40Mbs на 11 секунд. Вот моя конфигурация:

У кого-нибудь есть идеи, где может быть проблема? JBB.
