пакеты IGMP на внешнем и внутреннем интерфейсах есть

Ну вот и отлично! в чём теперь проблема?
По идее то устройство, что генерит multicast (на upstream интерфейсе) должно увидеть IGMP и понять, что на данном сегменте сети есть желающие получть этот трафик. После того, как данное устройство осознало столь значительный факт, ты должен незамедлительно получать multicast на upstream интерфейсе, который уже ядром будет доставлен на downstream интерфейс.

Eugene

Кстати, всем интересующимся. Можете uninstall/install igmpproxy package и попробовать. Патч наконец-то стал доступен.

filosoff96

Я невнимательно посмотрел на внешнем интерфейсе есть IGMP но он от удаленного устройства а не от моего шлюза
IGMP запросы ходят только по внутреннему интерфейсу

PS версию igmpproxy обновил через пакеты

Не уверен, что это корректно, на сколько я помню моя тестовая программулина (какой-то плэйер) слал membership report на 224.0.0.2, а внутри уже был адрес типа 239.255.0.147. Я гляну в RFC, как должно быть.

Попробуй добавить следующее
route add host 239.255.0.147 10.255.189.193

Пардон

так не бывает -)
netstat -rn опять пожалуйста и что говорит igmpproxy если запустить с debug?
