Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have BIND9 set up with proper recorders for my domain example.com, something.example.com is actually working...

When I have my DHCP server pointing at this DNS server I can get to webmin (https://something.example.com:10000) for the server it's pointing to. However I cannot get to any external websites (google.ca, serverfault.com, etc.)

I have my forwarders set in the named.conf.options file

options {
    directory "/etc/bind/";
    allow-query-cache { none; };
    allow-query { any; };
    recursion yes;

    forwarders {
        8.8.8.8;  // Google's DNS Server
        8.8.4.4;  // ''
    };
};

//zones here for example.com and reverse dns

But it doesn't seem to be forwarding requests to their servers. Where am I going wrong? Is there anything I can do to probe to get more information?

can this server actually use Google's DNS Servers? There might be a problem there, try for example a "dig @8.8.8.8 www.google.com" and see if it gives you reasonable results. –  Marcel G Jul 6 '11 at 20:50
    
Yes, it does work. Resolved, see below. –  user29600 Jul 6 '11 at 21:22

More of the config would be good; I'm going to guess you're missing one of the following items:

recursion yes; or allow-recursion { 10.x.x.x/8; }; (where 10.x.x.x/8 is your internal network)

recursion was set to no; set it to yes and it's still not working. I'll post the whole config, just didn't want to flood the page with useless crap. –  user29600 Jul 6 '11 at 20:38
    
I'm not seeing an allow-recursion block. Both of the snippets I listed are required. –  Shane Madden Jul 6 '11 at 21:01
    
Additionally, your allow-query-cache is, specifically, intentionally(?), blocking recursive queries. –  Shane Madden Jul 6 '11 at 21:10
    
Not intentionally, I was following an example I saw... should i have the allow-query in there? –  user29600 Jul 6 '11 at 21:12
    
Probably, yeah. Your exact settings depend on what this server does (any authoritative internet resolution, or just internal?), but generally speaking allow-query can probably be any;, while you'll want to set allow-query-cache and allow-recursion to internal subnets only. –  Shane Madden Jul 6 '11 at 21:15
