多宿主前向区域DDNS更新总是发送出相同的networking接口

我有一个多networking服务器“dhcp1”，networking接口“192.168.10.151”（eth0）和“192.168.0.151”（eth1）。 机器正在尝试使用具有networking接口“192.168.10.131”（eth0）和“192.168.0.131”（eth1）的名称服务器“ns1”的DDNS。 希望这些是我的dhcpd.conf的相关部分：

ddns-update-style interim; key DHCP_UPDATER { algorithm HMAC-MD5; secret "A6...=="; }; # The 'private' network. subnet 192.168.10.0 netmask 255.255.255.0 { zone example.com. { primary 192.168.10.131; key DHCP_UPDATER; } zone 10.168.192.in-addr.arpa. { primary 192.168.10.131; key DHCP_UPDATER; } ddns-domainname "example.com."; ddns-rev-domainname "in-addr.arpa."; option domain-name "example.com"; host client-private { hardware ethernet ...; fixed-address 192.168.10.13; } ... } # The 'public' network. subnet 192.168.0.0 netmask 255.255.255.0 { zone example.com. { primary 192.168.0.131; key DHCP_UPDATER; } zone 0.168.192.in-addr.arpa. { primary 192.168.0.131; key DHCP_UPDATER; } ddns-domainname "example.com."; ddns-rev-domainname "in-addr.arpa."; option domain-name "example.com"; host client-public { hardware ethernet ...; fixed-address 192.168.0.13; } ... } 

'ns1'服务器运行两个'named'实例，一个监听环回和专用networking接口，另一个监听公共接口。

问题

我的期望是当客户端请求在专用networking上'dhcp1'将在相应的专用接口（即'192.168.10.131'）上更新'ns1'的IP地址。 当客户端请求在该networking上的IP地址时，我也希望'dhcp1'在公共接口'192.168.0.131'上更新'ns1'。 虽然反向区域更新发生在相应的接口上，但是“dhcp1”总是启动两个networking的前向区域更新到名称服务器的公共接口（即“192.168.0.131”）。

我做错了什么，这是一个错误在isc-dhcp-server，function等？ 如果我没有提供足够的具体信息，请让我知道。 有关使用isc-dhcp-server和bind9的多宿主方法的networkingsearch对我而言并没有太多回报。

任何信息，你可以提供在赞赏。 谢谢。
