The thing is, such multicast packets might be useful for the upper layers of the protocol stack, but the firewall does not have enough granularity to tell "do not forward this packet but still pass them up". With unicast there is not such a problem (a packet goes only to one place). The warning was there just to remind [me] what was going on. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
