classless in-addr.arpa and recursion

[Evaldas Auryla]

Hello,

Software: BIND 8.2.2-P5 server with some security options (recursive
queries allowed only to local clients). This server is primary for some
zone "X" and has delegated classless in-addr.arpa for that zone.

Situation: Only local clients are able to resolve in-addr.arpa for that
zone "X", external queries are refused, because recursion is disabled -
it is however required for this zone to ask the secondary server
(usually ISP) what does that a.some-subnet-mask.b.c.d resolves to (CNAME
pointing to the real IP on ISPs server).

Question: Is there any way to enable recursion for some zones
(in-add.arpa) while keeping it off globally ?

Thank you,
Evaldas
