did you mean to say you dont wont others accessing your DNS server from outside your network?
If so, use iptables and block port 53 for any incoming connection apart from your lan.

You can do that with iptables as well by allowing port 53 from certain IPs

NOTE: When reading the man page on the above options, make sure you understand in which context the above options can be used. i.e. global, view, zone, etc...
