问题 问答题

【说明】
某公司基于Windows Server 2003操作系统的服务器安装并配置NAT+ DHCP服务,客户机可以通过该 NAT服务器访问Internet。内部局城网采用一台普通交换机连接工作站PC1~PCn,如图8-6所示。


【问题1】
在Server上进行NAT服务器配置时,若“接口2”的配置如图8-7所示,则其IP地址应设置为 (1) ,子网掩码应设置为 (2)

答案

参考答案:(1)202.200.117.34
(2)255.255.255.0

解析:这是一道要求读者根据具体应用环境掌握NAT服务器网卡的TCP/IP参数配置的分析理解题。本题的解答步骤如下。
在图8-6拓扑结构中的代理服务器上,依次单击“开始→程序→管理工具→路由与远程访问”,并在系统弹出的界面中打开“IP路由选择”目录树,然后用鼠标右键单击“NAT/基本防火墙”,选择“新增接口”命令。接着若选择接口1的“本地连接”,将进入到如图8-7所示的配置界面。
从图8-7所示的配置界面中可知,代理服务器的接口2被设置为连接到Internet网的公用接口。结合图8-6拓扑结构可知,分配给代理服务器的外网卡的IP地址是“202.217.6.34”,即,Internet服务提供商(ISP)分配给该企业的IP地址是202.200.117.34。因此(1)空缺处所填写的IP地址是“202.217.6.34”。
由于地址202.217.6.34是一个C类的IP地址,其默认的子网掩码为255.255.255.0,因此(2)空缺处所填写的子网掩码是“255.255.255.0.”。
