Bind9 在同一服务器上被拒绝

Bind9 在同一服务器上被拒绝

我有一个在 Docker 容器中运行的本地 BIND9 DNS 服务器。在另一个容器中，我运行 Wireguard，我用它从外部连接到我的家庭网络。

我遇到的问题是，当我选择服务器IP作为wireguard的DNS时，BIND9一直拒绝查询。如果我选择我的路由器作为 DNS（然后转发到 BIND9 DNS），一切都会按预期工作。

命名.conf.选项

# BEGIN MANAGED HOMENETWORK BLOCK
acl homenetwork {
  192.168.1.0/24; # home network
  172.17.0.1; # docker host
  192.168.4.0/24; # Wireguard network
  localhost;
  localnets;
};
# END MANAGED HOMENETWORK BLOCK
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.

    // forwarders {
    //  0.0.0.0;
    // };

有问题的 IP 是 BIND (Docker) 的 172.17.0.5、Wireguard (Docker) 的 172.17.0.7 和 192.168.4.2（Wireguard 客户端）。

错误

03-Oct-2023 20:44:52.999 client @0x7ff680007460 172.17.0.1#60081 (gitlab.lan): query 'gitlab.lan/A/IN' denied

我尝试将其设置acl为any;但产生了相同的错误，所以它一定是其他东西。有什么提示吗？

事实证明我zone也有这样的设置：

zone "lan" {
  type master;
  file "/var/lib/bind/lan.hosts";
  allow-query {
    192.168.1.0/24;
  };
};

我还需要更新该允许查询才能使其正常工作。我的最终配置现在如下所示：

命名.conf.local

zone "lan" {
  type master;
  file "/var/lib/bind/lan.hosts";
  allow-query {
    192.168.1.0/24;
    172.17.0.1; 
  };
};

命名.conf.选项

acl homenetwork {
  # home network
  192.168.1.0/24; 
  # docker host
  172.17.0.1; 
  localhost;
  localnets;
};
