会社のLANでいくつかのテストを実行するために内部専用サーバーを設定します。内部ドメインとホストについては信頼できますが、インターネット(Google、Yahooなど)のコンテンツを解析できるようにしたいです。
内部的な部分はうまくいくことができますが、公開的な問題を解決しようとすると失敗します。私の/etc/named.confに単純なフラグがありません(RHEL 7.3は私のOSです。btw)。
構成コンテンツを貼り付けることもできますが、ここから始めたいです。
私はそれを動作させるために非常に簡単に始めて、進行中にもっと追加する予定でした。現在経験している外部ソリューションの問題を解決するだけです。
ありがとうございます!

編集者:神経症。私はそれを見つけたと思います。オプションセクションで「転送者」を設定し、再帰をオンにする必要がありました。今私が望む方法で動作しています。

ここに私がDebianにあるものがあります/etc/bind
