BIND9 forwarders not working. Internal DNS resolves but doesn't forward requests it can't process

  • 772

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?

    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)
