Hi
   Thanks for your interest for the same .
actually if i want to block some zones in my dnsserver for users or for particular network or particular dns server (slave server )
at this point we need to put some acl for dns server right ??
i just want to understand how to allow or deny for slave servers or network or anything .
Am  not expert in dns server but i know how to make a server as a dnsserver  and i want to know how to make auto update to dns slave server

If u want to anymore questions for my doubt i can explain  again

One more time thanks for ur interest i really waiting for ur reply

Ya .. u can do it with iptables.......

I dont remember the dns port .. acc to me its 53 , plzz check

#iptables -A INPUT -s 192.168.8.2 -p tcp --dport 53 -j DROP

U can also update slave dns servers....by just changing
serial in forward zone...

Cheers
