Basic setup problem

[Bruce]

I have what I am assuming is a pretty basic problem in setting up
bind, due most likely to my having overlooked something obvious.

I have a web server "nancy" running Debian, which sits in a DMZ behind
a router. The server has a firewall, with the necessary ports for bind
open. I have a static IP address, say 0.0.0.0, which is forwarded to
"nancy" by the router.

I registered my domain name as example.org, and had my registrar
forward example.org to my static ip address, 0.0.0.0.

Having never set up my own domain name on my own box, what happened
with the above setup is that anyone typing http://www.example.org into
their browser would end up at my site; however, the address bar of
their browser would now read http://0.0.0.0 instead of
http://www.example.org.

I don't want this; I want the address to stay as www.example.org in
their address bar. A little research suggested that I have to install
a DNS server on my machine that will act as master for my domain
example.org, and that this would take care of the problem. From
reading the docs, it sounds as though I want to set this up as an
authoritative-only DNS server.

So, I installed the current version of bind9 (v. 9.2) from Debian
testing, and put the sample configuration for an authoritative-only
server from the bind manual
(http://www.bind9.net/Bv9ARM.ch03.html#sample_configuration) into
/etc/named.conf.local, changed all the references to "example.com" in
that file to my own domain, commented out anything about slave servers
(I don't have any (or perhaps don't understand what I am doing). This
is what I put in /etc/bind/named.conf.local:

  options {
     directory "/etc/namedb";           // Working directory
     allow-query { any; };              // This is the default
     recursion no;                      // Do not provide recursive
service
  };

  // Provide a reverse mapping for the 
  // loopback address 127.0.0.1
  zone "0.0.127.in-addr.arpa" {
     type master;
     file "localhost.rev";
     notify no;
  };
  // We are the master server for example.org
  zone "example.org" {
       type master;
       file "example.org.db";
  };

I now start up bind with /etc/init.d/bind9 restart. From the server
itself, everything works fine and going to www.example.org stays as
www.example.org in the address bar. However, from any other machine
going to www.example.org, the address bar still changes to the IP
address.

I am sure this is pretty basic, but I just haven't managed to figure
out where I went wrong. Any suggestions?

Thanks,
