第1题:
NAT(Network Address Translation)通过改变数据包的源(目的)(8)地址、源(目的)(9)来实现网络地址转换。 在Linux网关服务器中用iptables命令设置NAT规则。设Linux网关服务器有两个网卡,eth0接内网,eth1接外网。NAT服务配置命令如下:

(8)~(11)备选答案: A.POSTROUTING B. OUTPUT
C.PREROUTING D.IP
E.MAC F.端口号 G.192.168.1.0/24 H. 222.35.40.9/24
第2题:
● 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
end
[问题1]NAT按技术类型分为哪3种转换方式?
[问题2]请解释画线部分内容含义?
[问题3]此配置中采用了那种转换方式?

第13题:
Interface ge-0/0/2.0 of your device is attached to the Internet and is configured with an IP address and network mask of 71.33.252.17/24. A Web server with IP address 10.20.20.1 is running an HTTP service on TCP port 8080. The Web server is attached to the ge-0/0/0.0 interface of your device.

第20题:
Your network contains a server named Server1 that has the Routing role service installed. Server1 has two network connections. One network connection connects to the internal network. The other network connection connects to the Internet.All network connections connected to the internal network use private IP addresses. You install a Web server named Web1. Web1 hosts a secured Web site that only allows connections over TCP port 8281. Web1 is connected to the internal network.You need to ensure that the secure Web site can be accessed from the Internet.What should you do from the Routing and Remote Access console?()
