Nameservers Not Resolving
Here is my problem, I recently set up 2 dedicated boxes, and the idea is to have them server as a master and slave nameserver. I used some guides to create the different zone files for my domain.
I set up my two nameservers to be (ns1.lb-leo.com) and (ns2.lb-leo.com). I also went into my Godaddy account and added the ns1 and ns2 to the host summary pointing each of them to their static IP address, and then added the two nameservers to the actual domain.
This seems like I have the right solution, but here is my result:
I can ping my IP address from anywhere with no problem. I can even point directly to the IP address without a problem. However, I can't ping anything to do with the domain name. I thought this might be a firewall issue, so I turned the firewall completely off. If you do a port scan on the ip you will notice port 53 is open. On top of that, when I ping the actual nameserver ns1.lb-leo.com or ns2.lb-leo.com, it shows that it resolves to the IP but then the request times out. (I am not sure how ping really works behind the scene, but it shows the correct IP for a second).
Nslookup or ping on either of those servers, or even another server on the local network shows the correct results, but as soon as I go to an external location and ping or nslookup, it times out.
I also used DNS Stuff and it came back saying that all DNS servers have A records, but then when it checks the NS, it gives the error (A timeout occurred getting the NS records from your nameservers!)
Please help, I have tried everything I can think of or find on the internet, but no one has any answers.
This is my zone file:
$ORIGIN . $TTL 86400 ; 1 day lb-leo.com IN SOA ns1.lb-leo.com. webmaster.lb-leo.com. ( 2007122615 ; serial 10800 ; refresh (3 hours) 3600 ; retry (1 hour) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS ns1.lb-leo.com. NS ns2.lb-leo.com.

Welcome to the forums, pblackmon!
I don't know much at all about networking, but I think it can take up to a few days for nameserver changes to migrate across the web so that you can pull up a domain by name.
Maybe someone will correct if I'm mistaken.oz

OK, it looks like the provider is serving up the correct responses.

What is inportant is, are you using Views in your config file? It would help if we could see your named.conf file also.
Since you turned off the firewall and it still is not working I'm leaning towards the config file but cannot say that is the problem until I can see it.
It still might be nice to se the firewall rules just to be on the safe side that once the DNS config is fixed that the rules will allow everything to work.
The adventure of a life time.
