I don't agree with you in this case. If the server line noted above are
the default (which I support), I think there should also be an exception
for the listening IP subnet(s)/localnets. eg.

        server localnets { bogus no; };

Of course, there is also a difference between packets received from
outside the local net and inside. A local ip from a local server is
fine; the same address from an external server is suspect.
