nastaveni Bindu

Dobry den, chtel bych poprosit o pomoc s astavenim DNS serveru BIND. Mam domenu mojedomena.cz a server nekde pod verejnou adresou 1.2.3.4 Potreboval bych udelat to ze kdyz si z lokalni site zadam do prohlizece www.mojedomena.cz tak aby se to smerovalo na stranky www.mojedomena.cz ktere hostuji nekde jinede nez na serveru 1.2.3.4 ale pokud zadam webmail.mojedomena.cz tak aby se mi rozjelo roundcube na mem serveru za verejnou IP 1.2.3.4 Bind mam nastaveny takto:

named.conf

cat named.conf
// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind/README.Debian for information on the
// structure of BIND configuration files in Debian for BIND versions 8.2.1
// and later, *BEFORE* you customize this configuration file.
//

include "/etc/bind/named.conf.options";

// reduce log verbosity on issues outside our control
logging {
        category lame-servers { null; };
        category cname { null; };
};

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

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

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

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

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

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

zone "mojedomena.cz" {
        type master;
        file "/etc/bind/named.mojedomena.cz";
};

// add local zone definitions here
include "/etc/bind/named.conf.local";

// add local zone definitions here
include "/etc/bind/named.conf.local";

named.mojedomena.cz

cat named.mojedomena.cz
;
; BIND data file for local loopback interface
;
$TTL 86400
@ IN SOA mojedomena.cz. root.mojedomena.cz. (
2008081600 ; Serial

@ IN NS mojedomena.cz.
@ IN MX 10 mail.mojedomena.cz.
ns IN A 192.168.10.1
mail IN A 192.168.10.1
webmail.mojedomena.cz. IN A 192.168.10.1
www IN CNAME 192.168.10.1
smtp IN CNAME mojedomena.cz.

Pokud zadam do localniho postaka mail.mojedomena.cz tak vse funguje jak ma, pokud zadam lokalne webmail.mojedoman.cz tak se dostanu na stranky roundcube kde mam postu na lokalni serveru ale pokud zadam www.mojedomena.cz tak mi napise ze nemuze domenu najit, takhle blbe to chodi jen lokalne. Pomuze mi prosim nekdo z nastavenim Bindu?
