As the NFPROTO_* thing is only internal used by xtables, not by the hooks. The hooks use the protocol family, and we've been using NF_ARP to 0 by now. > Define "does not work". Do you mean arptables sees no packets? arptables sees *no packet at all*. The ARP mangling does not work. Try: arptables -o eth0 -l 6 -I OUTPUT -j mangle --mangle-mac-s 00:15:58:28:5a:30 and tcpdump the arp request. > Perhaps the following helps? Yes, your patch will also work, but it introduces an inconsistency in the naming used to register hooks in the family field. -- "Los honestos son inadaptados sociales" -- Les Luthiers -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
