If IP Forwarding and IP Firewall are both included in a kernel, shouldn't the
default policy be to not forward anything until the system startup scripts set
the appropriate policies? Otherwise, there's a window of time during boot when
packets will be forwarded but should not be. Worse still, if a crash causes a
reboot that doesn't get far enough to run the startup scripts, a machine might
be left with forwarding turned on indefinitely until someone notices the
problem.
