启用 DNS 转发 Bind9

问题描述

我在 Ubuntu 中有一个 bind9。它可以很好地解析我实验室域 xutilab.local 的 DNS 名称，但是如果我请求类似 www.google.com

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; };

这里缺少任何选项吗？

非常感谢。

解决方法

在此块（选项）内，尝试添加：

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

,

我终于发现问题出在我的路由器上，它有一个与 DNS 安全相关的选项。禁用它，Bind9 能够以当前配置正常转发请求。

谢谢！
