路由器配置中,创建一个名字为cisco含有30个地址的动态NAT池的命令是()。
第1题:
随着Internet迅速发展,公网IP地址短缺已成为一个十分突出的问题。为了解决这一问题,出现了多种解决方案。而使用路由器的NAT/NAPT(Network Address Translation/Network Address Port Translation)功能是其中一种解决方法。
如图5-1所示,某企业通过租用ISP的线路(获得的公网IP网段为:218.94.86.0/29,除去两个互联的IP地址),实现企业的电子商务。其中,有一对外的Web服务器(内网IP地址为192.168.0.100/24),一OA服务器(内网IP地址为192.168.0.101/24)。

以下是本端路由器的配置摘要,请解释其中部分语句的含义(“//”后为注释内容)。
version 11.2 //版本
!
hostname RouterCOM //路由器名称
!
interface Seria10 //串口0
ip address 218.94.86.2 255.255.255.248 //串口0的ip地址
ip nat outside (1)
!

● 试题五
NAT英文全称是"Network Address Translation",中文意思是"网络地址转换",它是一个IETF(Internet Engineering Task Force,Internet工程任务组)标准,允许一个整体机构以一个公用IP(Internet Protocol)地址出现在Internet上。顾名思义,它是一种把内部私有网络地址(IP地址)翻译成合法网络IP地址的技术,如图4所示。
某公司通过专线上网,申请的合法Internet IP地址段为192.1.1.1~192.1.1.10,使用路由器的NAT功能进行地址转换,具体配置如下:
Current configuration:
version 11.3
no service password-encryption
hostname 2501
ip nat pool aaa 192.1.1.2 192.1.1.10 netmask 255.255.255.0
ip nat inside source list 1 pool aaa
interface Ethernet0
ip address 10.1.1.1 255.255.255.0
ip nat inside
interface Serial0
ip address 192.1.1.1 255.255.255.0
ip nat outside
no ip mroute-cache
bandwidth 2000
no fair-queue
clockrate 2000000
interface Serial1
no ip address
shutdown
no ip classless
ip route 0.0.0.0.0.0.0.0 Serial0
access-list 1 permit 10.1.1.0.0.0.0.255
line con 0
line aux 0
line vty 0 4
password cisco
