Ubuntu 14 - multicast z 2 interfacov

[dzano]

Ahojte,
viete mi prosim niekto pomoct s konfiguraciou siete na Ubuntu 14.
Mám 2 sieťové interface:
eth0 - access interface, prístup na internet + zdroj multicast group 239.0.0.0 255.0.0.0
eth0.1008 - trunk interface, zdroj multicast group 233.0.0.0 255.0.0.0

Nech robím, čo robím, beží mi len multicast z eth0 ale z vlany 1008 nie... unicastové IP z 1008 viem opingovať.

auto eth0
iface eth0 inet static
   address 192.168.43.252
   netmask 255.255.252.0
   network 192.168.40.0
   broadcast 192.168.43.255
   gateway 192.168.43.254
   dns-nameservers 8.8.8.8 8.8.4.4
   post-up route add -net 239.0.0.0 netmask 255.0.0.0 dev eth0
   post-up ifconfig eth0 multicast

auto eth0.1008
iface eth0.1008 inet static
   address 13.0.0.150
   netmask 255.255.255.0
   vlan-raw-device eth0
   post-up route add -net 233.0.0.0 netmask 255.0.0.0 dev eth0.1008
   post-up ifconfig eth0.1008 multicast

Ďakujem za každú pomoc...
