How exactly are you changing the MAC address? What hardware are you running?

DETAILS The incoming packets can be observed with `tcpdump -lni eth0`, but not with `tcpdump -lni any`, nor do they increase INPUT packet count when observed with `iptables -vL`. The problem goes away immediately when the original mac address is set. WORKAROUND Don't change the MAC address from the original.
