iptables/netfilter operates at layer 3. therefore, packets generated or
received at layer 2 cannot be blocked with iptables/netfilter.
ethereal/iptraf operate at the BPF layer (layer 2), and arp packets are
layer 2 as well.
iptables/netfilter is not at fault; you have an invalid testing
methodology.
