I'm haven't tested this, but I'm pretty sure that this will take care of
the problem...

In the /etc/rc2.d/SXXinet file, hack it so it DOESN'T do a
	ndd -set /dev/ip ip_forwarding 1
and does instead
	ndd -set /dev/ip ip_forwarding 0

That way, if for some reason, the fwd process doesn't start, you aren't
left testing the wind speed with a delicate part of your anatomy.

The reason this works is cuz, fwd (apparently) increments the
ip_forwarding value on start-up.
