When I comment the setsockopt MULTICAST_IF option, all work fine and destination packets to the multicast adress have AH added before IP Header. But when I use the setsockopt MULTICAST_IF, no packets are sended from the interface (packet seems to be destroyed silently by kernel). Is there an issue about using MUTLICAST_IF option and IPsec ? Any help will be greatly appreciated. Regards, spe. -- spe@selectbourse.net
