Since you have "allow-query {wemadenets;};", clients outside that
network will NOT be allowed to make recursive requests against your
server.
But if you really don't want to change the allow-query option, you can
put "allow-query {any;};" within all the zone stanzas. That will just
allow public queries for those zones, not for recursive or cached data.
