You can also make a similar argument that if the software requests DNS
lookups and nothing's been firewalled, then the **ONLY** correct behaviour
is to fulfil the request.
There is a contradiction here. An operation is requested and configured to
be available in the firewall, but configuration blocks it elsewhere.
Calling any particular behaviour a 100% solution is IMO naïve.
