Unlike IPFW, IPF defaults to "open" (thus the reason for the
IPFILTER_DEFAULT_BLOCK kernel option). Thus IPF won't be blocking any of
the packets that IPNAT is NATing. For example, when I issue a `ipf -F
a`, my IPNAT rules continue to function normally.


The person who takes the banal and ordinary and illuminates it in a new way can 
terrify.  We do not want our ideas changed.  We feel threatened by such 
demands.  "I already know the important things!" we say.  Then Changer comes 
and throws our old ideas away.
