VPND（Virtual Private Network）是通过使用服务器和防火墙技术将外部IP地址映射到内部服务器，以实现内部网络的访问和管理，在配置VPND时，需要设置相关的配置文件，如VPND.DNS文件和VPND.DNS settings文件,以控制服务器的访问权限和防火墙的配置。
安装和配置DNS服务器
- 确保您有一个服务器，通常用于VPND，配置一个内部DNS服务器，可能需要使用
DNS-Server工具来为服务器配置IP地址、端口和日志等信息。 - 确保防火墙（如
iptables、pamfirewall等）支持VPND配置。
设置VPND.DNS文件
VPND.DNS文件是配置VPND的基础文件,格式如下：
[root@server] dpn
[root@server]：表示您正在管理server服务器。dpn：表示您正在创建VPND配置。root：表示您正在管理根用户。server：表示您正在管理server服务器。
设置VPND配置
在VPND.DNS文件中,设置VPND的配置项：
- VPNNIP：指定VPNN的IP地址。
- VPNNPort：指定VPNN的端口编号。
- VPNNName：指定VPNN的名称（可选，如果只使用IP地址，名称可以省略）。
- VPNNAuth：指定VPNN的 auth 配件名称（可选，如果只使用IP地址，auth 配件名称可以省略）。
- VPNNPass：指定VPNN的 pass 配件名称（可选）。
- VPNNDir：指定VPNN的子网IP的起始IP地址。
- VPNNAutoSave：指定是否自动保存VPNN配置（默认为“是”）。
[root@server] dpn VPNNIP: 192.168.1.1 VPNNPort: 8 VPNNName: www VPNNAuth: alice VPNNPass: password VPNNDir: /server VPNNAutoSave: yes
设置VPNN防火墙规则
在VPNN防火墙规则中,设置规则以阻止外部IP地址访问VPNN：
- 规则1：阻止所有外部IP地址访问VPNN。
- 规则2：如果VPNN支持子网掩码（如IP地址），设置规则以阻止外部IP地址访问VPNN的子网IP。
设置VPNN的 auth 配件
如果您使用 auth 配件，您需要为VPNN配置 auth 配件：
- 在VPNN.DNS文件中，添加以下内容：
VPNNAuth: alice VPNNPass: password
- 在VPNN auth 配件中，设置以下内容：
alice: www www: 8 https: 443 https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https: https https
