nastaveni DNS

[Petr Hudeček <pheek zavinac seznam bod cz>]

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
10800 ; Refresh
1800 ; Retry
1209600 ; Expire
604800 ) ; Negative Cache TTL

@ IN NS mojedomena.cz.
@ IN MX 10 mail.mojedomena.cz.
ns IN A 192.168.10.1
mail IN A 192.168.10.1
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?
