Errr, unless I'm looking at the wrong online manual, DNS relay does
_exactly_ what you want.  You just have to give it a local domain name
and fill in the dhcp reservation table with the related name/ip/mac
sets.  The fact that it wants a name in this table should have been a

After you've set that up, test it with 'dig @ name.localdomain'.
