Easy... don't disable recursive lookups.
Without recursive lookups, your DNS server will only respond to queries
about things that it knows... i.e. the dns entries hosted on your server.
In order for it to resolve domains that it knows nothing
to look up non-local domains. So, I need to be able to restrict the
facility of recursive lookups to the local IPs. I can't see any way to do
that.

I have a problem in that when I disable Recursive look
ups the DNS servers then fail to answer DNS queries
from the local IP addresses.
In BIND you can set the bind.conf file to only allow certain IP address to
be able to initiate a recursive query.
The directive is in the options section:

and do a recursive lookup
