named.conf.master ISPconfig duplication
 
Our team had modified named.conf.master to make external view and internal view to enhance security.
But the problem is, that ISPconfig, when it use the template, it double each zone in each view: internal and external......
So in named.conf there is four same zones, but i only want two.

here a sample of named.conf

Code:

view "internal-in" in {
        // Our internal (trusted) view. We permit the internal networks
        // to freely access this view. We perform recursion for our
        // internal hosts, and retrieve data from the cache for them.

        match-clients { trusted; };
        recursion yes;
        additional-from-auth yes;
        additional-from-cache yes;
        allow-query {
                any;
        };

        allow-transfer {
                any;
        };

        // prime the server with knowledge of the root servers
        zone "." {
                type hint;
                file "db.root";
        };

        // be authoritative for the localhost forward and reverse zones, and for
        // broadcast zones as per RFC 1912

        zone "localhost" {
                type master;
                file "db.local";
        };

        zone "127.in-addr.arpa" {
                type master;
                file "db.127";
        };

        zone "0.in-addr.arpa" {
                type master;
                file "db.0";
        };

        zone "255.in-addr.arpa" {
                type master;
                file "db.255";
        };

        zone "XX.191.88.in-addr.arpa" {
                type master;
                file "pri.XX.191.88.in-addr.arpa";
        };
        zone "XX.191.88.in-addr.arpa" {
                type master;
                file "pri.XX.191.88.in-addr.arpa";
        };


        zone "sd-XXXX.dedibox.fr" {
                type master;
                file "pri.sd-XXXX.dedibox.fr";
                allow-query { any; };
        };
        zone "sd-XXXX.dedibox.fr" {
                type master;
                file "pri.sd-XXXX.dedibox.fr";
                allow-query { any; };
        };


};

view "external-in" in {
        // Our external (untrusted) view. We permit any client to access
        // portions of this view. We do not perform recursion or cache
        // access for hosts using this view.

        match-clients { any; };
        recursion no;
        additional-from-auth no;
        additional-from-cache no;
        // Link in our zones
        // prime the server with knowledge of the root servers
        zone "." {
                type hint;
                file "db.root";
        };

        // be authoritative for the localhost forward and reverse zones, and for
        // broadcast zones as per RFC 1912

        zone "XX.191.88.in-addr.arpa" {
                type master;
                file "pri.XX.191.88.in-addr.arpa";
        };
        zone "XX.191.88.in-addr.arpa" {
                type master;
                file "pri.XX.191.88.in-addr.arpa";
        };


        zone "sd-XXXX.dedibox.fr" {
                type master;
                file "pri.sd-XXXX.dedibox.fr";
                allow-query { any; };
        };
        zone "sd-XXXX.dedibox.fr" {
                type master;
                file "pri.sd-XXXX.dedibox.fr";
                allow-query { any; };
        };


};

here's a sample of named.conf.master
Code:

acl "xfer" {
        127.0.0.1;
};

acl "trusted" {
        127.0.0.1;
};

options {
        pid-file "/var/run/bind/run/named.pid";

these samples are from http://www.howtoforge.com/forums/showthread.php?t=5865
we have the same problem, someone said that the problem is in this file:

/root/ispconfig/scripts/lib/classes/ispconfig_bind.lib.php
so here's a sample of it
tell me what we should modify in it.
