    Hi guys!

    I have setup a CENTOS 5 dns server.
    Everything is working fine, even the load balance feature.
    Now the problem starts when I login to remote linux server and type
    the command:

    [[email protected] ~]# nslookup mydomain.com
    ;; reply from unexpected source: 196.28.239.xx#53, expected
    ;; reply from unexpected source: 196.28.239.xx#53, expected
    ;; connection timed out; no servers could be reached

    [[email protected] ~]# nslookup mydomain.com
    Server: 196.28.239.xx
    Address: 196.28.239.xx#53

    Name: mydomain.com
    Address: 196.28.239.xx
    Name: mydomain.com
    Address: 196.46.2.xx

    Sometimes the answer comes from my WAN1 and sometimes answer comes
    from WAN2.
    This is not good, I want to get the answer from the ip I requested.

    Any help please?

    Check the named.conf configuration below:
    recursive-clients 100;
    //interface-interval 0;
    minimal-responses yes;
    //notify no;
    recursion yes;
    version "";
    transfer-format many-answers;
    allow-recursion {;;};
    //allow-notify { localhost; };
    allow-transfer { localhost; };
    forwarders { 196.28.xx.xx; 196.46.0.xx;};
    listen-on port 53 {any;};
    query-source address * port 53;
    notify-source * port 53;
    transfer-source * port 53;
    auth-nxdomain no;
    directory "/var/named";
    dump-file "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";

    The router is a Dlink LB604. Load balance is enabled, but I don´t
    think that´s the problem since i have tested with load balance
