SV: Tricky DNS configuration. Help!

[Johnny Damtoft]

Hi...



We have the forwarders 10.10.10.*, you have some options on this kinds
forwarding.. first, always or default

If you do it like this, every query that comes to the DNSserver (non
intranet) goes to your Internet Forwarders.

And if its a query for the domain.intra it askes the 10.10.10.1 server =
for
that.


options {
	directory "/etc/dns";
	pid-file "/var/run/named.pid";
	forward first;
	forwarders {
		10.10.10.1;
		10.10.10.2;
		};
	};

zone "domain.intra" {
        type master;
        file "/etc/namedb/intra/domain.intra";
        forwarders { 10.10.10.1; };
        also-notify {
                10.10.20.2;
                };
        notify yes;
        };

I hope that this helps you :)
