mydns and named

hello, i have a ispconfig 3 on a centos 5.3 i386 installed, and today i tried to make my ispconfig server secondary client DNS server .... what i mean exactly?

i have a routing server for my company, for my network, on wich i use named to make DNS forward like this:

/var/named/chroot/etc/named.conf

options {
// Relative to the chroot directory, if any
directory "/etc";
pid-file "/var/run/named/pid";
dump-file "/var/dump/named_dump.db";
statistics-file "/var/stats/named.stats";
// listen-on { 127.0.0.1; 193.xxx.xxx.1;};
// query-source address 193.xxx.xxx.1 port 53;
allow-query { any; };
forwarders {
193.xxx.xxx.10;
193.xxx.xxx.2;
};
};


this is the config from my network routing server.
i tried to create same named.conf on the ispconfig server,but when i started named, all the domains registered on the server just stopped .... not being recognized ......

i know there a conflict between namd and mydns, so i want to ask u if u can help me configure the mydns to usr as a DNS forwarder for my Internet Service Provider DNS`s, exactly as i m using the network router.

thanks in advance
