Всем привет.
Есть такая задача:
Надо маршрутизировать мультикаст трафик, который принимается интерфейсом xxx.xxx.xxx на 192.168.0.1. Поставил себе mrouted
/etc/mrouted.conf
tunnel 192.168.0.1 239.0.0.100
запускаю mrouted -c /etc/mrouted.conf -d
[root@nevsky /]# mrouted -c /etc/mrouted.conf -d
debug level 0x2de (pruning,routing,peers,cache,interface,membership,igmp)

вродьбы все как положено, но потом после кучи запросов от машин с сети xxx.xxx.xxx/24 происходит такое:

В чем дело. Я уже лоб поломал.
