Vps – Name Servers not resolving

bindcentos6domain-name-systemvps

I just got myself an unmanaged Dedicated VPS from OVH and I don't have a prior experience of setting up servers or DNS servers but I followed a couple of tuts and installed webmin and created NS Zones for my Domain but now I'm having a weird issue where mxtoolbox and intodns.com are saying that no NS records are found for my Domain although I did register ns1.example.com and ns2.example.com with my domain registrar (which is Network Solutions in this case) but it still keeps failing and I am unable to access the website. I have been looking for a solution for 2 days now and I still haven't gotten one. Also, I am using CentOs 6.3. Here is my BIND config which I got from Webmin

//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.

My hosts file:-

Do not remove the following line, or various programs
that require network functionality will fail.

127.0.0.1       localhost.localdomain localhost

198.245.51.xxx  ns1

198.245.51.xxx  example.org

198.245.51.xxx  ns1.example.org

198.245.51.xxx  ns1.example.org.

My resolv.conf file:-

namserver 198.245.51.xxx
ns1.example.org 198.245.51.xxx
ns2.example.org 8.33.137.xxx
nameserver 127.0.0.1
nameserver 213.186.33.xx
search ovh.net

intodns.com results:-

Note:- Just in case there is any confusion regarding the domain example.org, I just use this alias to mask my domain name but I'm pretty sure you guys already figured that out so just putting it out there.

Thank you very much for your reply!

Please let me know if you need anymore info.

You may have a firewall running, and as i remember CentOS's default firewall block port 53 (though i may be wrong here).

Change 

allow-query     { localhost; any; };

with 

allow-query     { any; };

maybe that causing some problem. Also delete the : 

forwarders {
198.245.51.xxx;
8.33.137.xxx;
};

since i believe that 2 IP is your own IP.

Restart bind, and after restart check that is really running with ps -ef | grep bind .
