Just put a "listen-on" directive in your /etc/named.conf (assuming you are
running bind 8).  I use

        listen-on {
                192.168.0/24;
                127/8;
        };

You will of course need to modify this for your setup.  Check the
documentation in the bind-doc package for details.
