To se mi nezdá...
Vždy ve Firewallech i v NAT je jak označování multicastových adres tak se dá označovat IGMP. Pravda ,v manuálu jsem nenašel jedinou zmínku o Routování Multicastů ,ale pokud vim tak v Linuxu je něco s Multicasty tudíž nevim proč by na MK nemělo být.
A podporuje třeba vaše katra multicasty?:
