Greetings,

I have had this error before but I was always able to find the problem (or
blame the service provider).  I have a cable modem, FreeBSD-3.1-RELEASE,
and I am running NATD for my home network just fine.  I set up a
3.2-RELEASE box for a friend with a cable modem (same provider) and when I
bring the FreeBSD box online I get the dreaded "natd: failed to write
packed back" error.

I know the NIC is good because I used it to communicate on my network
before connecting to my friends cable modem.  I know the cable between the
NIC and the cable modem is good because it is the same one my friend was
using to connect his Win95 box to the cable modem.  I know the cable modem
is good because when we connect the Win95 box back to the modem the service
works just fine.

I configured this machine exactally the same way as I have mine.
IPFIREWALL and IPDIVERT are in the custom kernel, gateway_enable="YES",
NATD interface set correctly, the whole 9 yards.  My friend and I are
actually on the same leg for our service and only 7 IP addresses away from
each other.  We use the same defaultrouter and netmask.  I don't understand
what could be causing the FreeBSD box to not work.  Any insight would be
greatly appreciated.

Thank you,
Matthew Hagerty
