Question : can't transfare only on zone (on-authoritative answer )

I am having problem transfaring only (db.external.192.168.1) zone from master to slave. all other zones copied from master to slave except this one, the error i am getting is:

###Jul 21 17:31:14 BINDt-test named[17492]: zone 1.168.192.in-addr.arpa/IN/external: refresh: non-authoritative answer from master 10.1.3.30#53 (source 0.0.0.0#0)###

master IP:10.1.3.30
slave IP: 10.1.3.176

Any idea why is that?

1-  master server zones

view "external" {
    match-clients { ANY; };
    recursion no;
    additional-from-auth no;
    additional-from-cache no;

    zone "testserver.org" in {
        type master;
        file "db.external_auis.org";
        allow-update { none; };
        allow-transfer { 10.1.3.17; };
    };

    zone "1.168.192.in-addr.arpa" in {
        type ;
        file "db.external.192.168.1";
        allow-update { none; };
        allow-transfer { 10.1.3.17; };
 };

};

include "/etc/tsig.key";

2- slave server zones:
view "external" {
    match-clients { ANY; };
    recursion no;

    zone "testserver.org" in {
        type slave;
        file "bak.external_auis.org";
        masters { 10.1.3.30; };
    };

   zone "1.168.192.in-addr.arpa" in {
        type slave;
        file "bak.externali_auis.org";
        masters { 10.1.3.30; };
    };

};


Zone File ( db.external.192.168.1)
TTL    86400
$ORIGIN        1.168.192.IN-ADDR.ARPA.
@              IN SOA  testserver.org. admin.testserver.org. (

                                        3H              ; refresh
                                        15M             ; retry
                                        1W              ; expiry
                                        1D )            ; minimum
; server host definitions
        IN  NS          ns1.testserver.org.

Answer : can't transfare only on zone (on-authoritative answer )

This just an edit typo in your reverse lookup zone definition?

>         type ;

I suggest you make that "type master;".
