Yes I understand that, but still I need some advice on how to make that happen, cause its really vital for what I m trying to do. How can I make the QUEUE target of netfilter receive packets as if it was in "promiscuous" mode? to put it in another way, I would like the QUEUE target to receive whatever shows up on ethereal (which is all traffic on the hub). Having both the the primary and the backup share the same IP/MAC, the packets from the primary dont go up netfilter in the backup. How can I make this happen, or at least "fake" something in the backup so that I make it happen.... Thanks for your reply.
