Delegating subzone of a not valid domain.

[Samuel Abreu de Paula]

Hi, in my lan domain im trying to delegate subzones to others name
servers, but im failing hard.

Lets say domain "acme":

ns1.acme server, file acme.zone:
$TTL    604800
@       IN      SOA     ns1.acme. admin.acme. (
                                    19         ; Serial
                                  7200         ; Refresh
                                   120         ; Retry
                               2419200         ; Expire
                                604800)        ; Default TTL
;
@                                       IN      NS              ns1.acme.
acme.                                   IN      A               10.0.0.3
ns1                                     IN      A               10.0.0.3
www                                   IN      A               10.0.0.1

sub1.acme.                          IN      NS            ns1.sub1.acme
ns1.sub1.acme.                    IN      A               192.168.1.3



ns1.sub1.acme server, file sub1.acme.zone:
$TTL    604800
@       IN      SOA     ns1.sub1.acme. admin.sub1.acme. (
                                     3         ; Serial
                                  7200         ; Refresh
                                   120         ; Retry
                               2419200         ; Expire
                                604800)        ; Default TTL
;
@                                       IN      NS              ns1.sub1.acme.
sub1.acme.                              IN      A               192.168.1.3
ns1                                     IN      A               192.168.1.3
www                                   IN      A                192.168.1.1


Now, if i do: dig @192.168.1.3 www.sub1.acme
Returns ok.

If i try: dig @10.0.0.3 www.acme
Returns ok

But if i try: dig @10.0.0.3 www.sub1.acme
Returns NXDOMAIN

To make it work, i only finded 2 solutions.

Add a forward zone on ns1.acme for the domain ns1.sub1.acme, or add
ns1.acme (10.0.0.3) as a slave for sub1.acme domain.

What i want, is not need the forward zone or the top name server as a
slave to the sub zone, but dont know what im missing.

Thanks.
