I'm back looking at this, but must admit I'm completely confused now :-) I could add an IPv4 sysctl to control this behaviour: 0 - off 1 - RFC 1122 "SHOULD" 2 - also drop unicast-in-multicast (for wireless) But I guess due to cluster-IP it would have to default to 0. However, talk about ip_local_deliver_finish() in this thread has me wondering if we could just implement it using iptables? I guess ipt_addrtype and ip6t_addrtype would let me do that? johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
