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
connect directly to my old ISP's servers, is now behind this box. I'm
running a GENERIC 4.0 kernel which has never had any problems with my
hardware.

And, as far as getting the obsd box to talk to the modem was concerned,
that's it! There is other stuff involved in getting the box to talk to
the lan and v/v. I found it useful getting just the box to work with the
modem, it's not clear in your message if that is also your situation.

Possibly a silly question -- how are you connecting the cable modem to your
OpenBSD server's external interface? Are they all plugged into a switch or
hub or are you using a cable from the external interface directly to the
cable modem?

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.
Thinking to reconfigure the cable-modem box myself (as opposed to
going with th
Also, I just noticed in my cable-modem box's configuration page that
the WAN gateway is 24.145.134.65, which reverse dns shows to be
user-0c931i1.cable.mindspring.com.
Isn't it odd that my gateway is another user rather than the ISP?
Should I be worried about all this?
