That message means that your slave name server received a dynamic
update, which it normally would have forwarded to its master name
server for the zone.  However, it didn't because either you didn't
have an allow-update-forwarding substatement in the corresponding
zone statement or the allow-update-forwarding substatement didn't
allow forwarding updates from that IP address.
