As per above, the tcpdump output suggests a more likely misconfiguration of the cable modem rather than the BSD box.
I'm starting to wonder if it's been deliberately (mis-)configured this way.

It looks like the reset button has been removed! And I can't find a reset button in the web interface---that's probably Motorola's default setting. J
