Which is important given the number of NAT setups that only perform NAT
for the ranges they deal with and leave everything else alone. NATing
all traffic may not be ideal in some cases, but filtering traffic that
isn't desired is critical. Establishing an initial connection is, of
course, necessary so that the server recognizes what the source address
should be.
