[CentOS] Centos 6 - named with internal zone file and forwarding

Hi All,

I have two Centos 6 servers running BIND.

I have configured the two servers to run internal zones as a master /
slave setup.

My gateway runs DNSmasq and I would like all other requests for lookups to
be sent to the DNSmasq system.

I have added the following:

forward first;
  forwarders {
    172.16.0.1;
  };

Where 172.16.0.1 is the host running DNSmasq.

For some reason I still cannot resolve anything outside my network.

Any pointers?

Thanks

Giles
