Here's some snippets from my named.conf that has internal and external
views.  I've chopped out a bunch to make it shorter for posting but
there should be enough there to give you the idea as to what you're
looking to do.  I am assuming you're running bind 9.  If you're still at
bind 8, you need to upgrade.

# Local networks
acl "local-nets" { 192.168.0.0/16; 127.0.0.0/24; };

view "internal" {
   match-clients { local-nets; };
   recursion yes;
   allow-query { local-nets; };
   allow-transfer { local-nets; };
   zone "." {
	type hint;
	file "named.ca";
   };
   zone "0.0.127.in-addr.arpa"{
	type master;
	file "named.local";
   };
   zone "ewilts.org"{
	type master;
	file "ewilts.org-internal";
   };
   zone "0.168.192.in-addr.arpa"{
	type master;
	file "0.168.192.in-addr.arpa";
   };
   zone  "localhost" {
        type master;
        file  "localhost.zone";
   };
};

view "external" {
   match-clients { any; };
   recursion no;
   allow-query { any; };
   zone "." {
	type hint;
	file "named.ca";
   };
};
