我正在尝试使用 Bind9 (Linux) 部署 A dns Forwarder。我希望我的服务器能够分析请求并将其转发到外部 DNS（互联网）或内部使用条件实现。因此，我们将使用： DNS 转发器：将分析请求并将请求转发到内部或外部 DNS 的服务器 内部 DNS：仅解析内部名称（domain.company）的服务器 DNS：8.8.8.8 ：解析外部地址

所以目标是当我尝试解析域名/URI 时。如果是内部请求，则应将其转发到内部 DNS，否则应将其转发到 8.8.8.8

Exemple1 : nslookup google.com should be forwarded to 8.8.8.8

Exemple2 : nslookup application.domain.company should be forwarded to internal dnsserver

这里是 /etc/named.conf 的内容

//
// named.conf


options {
        listen-on port 53 { 127.0.0.1; };
        listen-on-v6  { any; };
        auth-nxdomain no;
        directory       "/var/named";
        dump-file       "/var/named/data/cache_dump.db";
        statistics-file "/var/named/data/named_stats.txt";
        memstatistics-file "/var/named/data/named_mem_stats.txt";
        recursing-file  "/var/named/data/named.recursing";
        secroots-file   "/var/named/data/named.secroots";
        recursion yes;
        allow-query     { 127.0.0.1; IPCLIENT2; IPclient1; };
        forwarders {
                8.8.8.8;
                        };
        forward first;


        dnssec-enable yes;
        dnssec-validation auto;

        /* Path to ISC DLV key */
        bindkeys-file "/etc/named.root.key";

        managed-keys-directory "/var/named/dynamic";

        pid-file "/run/named/named.pid";
        session-keyfile "/run/named/session.key";
};

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};
zone "domain.compagny" IN {
        type forward;
        forward only;
        forwarders { IP_internaldns; };
};
    zone "domain2.compagny" IN {
        type forward;
        forward only;
        forwarders { IP_internaldns; };
};

#include "/etc/named.rfc1912.zones";
#include "/etc/named.root.key";

在这里，如果我执行：nslookup google.com or yahoo它会正确解析但是如果我执行nslookup application.domain.compagny它会显示：找不到 XXXXXXXX: SERVFAIL

谢谢

您指的是 "company" 还是 "compagny" ?

尝试以下区域配置：

zone "domain.company" {
        type forward;
        forwarders { IP_internaldns; };
};
zone "domain2.company" {
        type forward;
        forwarders { IP_internaldns; };
};
