Recursive query

[Hisham Al Saad]

Hi,

I'm running BIND 9.2.5 on a linux server, currently recursion is
allowed for all,  i need to allow it to do global recursive queries
only from my specific set of authorized networks (clients).
At the same time i need to allow all foreign addresses to query my local zo=
nes.=20
Is all what i have to do here is to add an allow-recursion statement
and list all my networks ??
Please advice,
Thanks in advance.
Hisham
