As per above, the tcpdump output suggests a more likely

I'm starting to wonder if it's been deliberately (mis-)configured
this way.
Thinking to reconfigure the cable-modem box myself (as opposed to

Right, this is what first puzzled me too.
You might use tcpdump or similar on your internal network to
determine what kind of traffic it relates to.

Possibly a silly question -- how are you connecting the cable modem to your

Hi guys,
I recently switched ISPs, and my new ISP (Time-Warner) gave me a
Motorola SBG1000 cable-modem box. My OpenBSD machine, which used to

running a GENERIC 4.0 kernel which has never had any problems with my
hardware.
