启用DNS转发Bind9

Question

我在Ubuntu有一个bind9。它可以很好地为我的实验室域xutilab.local解析DNS名称，但是如果我请求类似于www.google.com的内容，它就不能工作了。

这是named.conf.options文件：

options {
    directory "/var/cache/bind";

    // If there is a firewall between you and nameservers you want
    // to talk to, you may need to fix the firewall to allow multiple
    // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

    // If your ISP provided one or more IP addresses for stable
    // nameservers, you probably want to use them as forwarders.
    // Uncomment the following block, and insert the addresses replacing
    // the all-0's placeholder.
     allow-query {
        any;
    };

    forwarders {
            8.8.8.8;
    };

    //========================================================================
    // If BIND logs error messages about the root key being expired,
    // you will need to update your keys.  See https://www.isc.org/bind-keys
    //========================================================================
    dnssec-validation auto;

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { any; };
    notify yes;
    allow-transfer { any; };

这里有遗漏的选项吗？

非常感谢。

Answer 1

最后，我发现问题在我的路由器中，它有一个与DNS中的安全性相关的选项。禁用它，Bind9就能够将请求转发到当前配置。

谢谢!

在这个块中(选项)，尝试添加：

allow-recursion { any; };
allow-query { any; };
allow-query-cache { any; };
