考题
You have just installed a new web server on the Testking network. You are required to ensure that the web server is accessible from the Internet. The network uses private addressing, so an IP-to-registered address mapping is required.To do this, you enter the following command:TestKing(config) ip nat inside source static 192.168.2.1 198.18.1.254 You unsuccessfully try to ping the Internet from a PC host on the LAN. During the troubleshooting process, you enter the show ip nat translations command but the output is blank.What is the most likely cause of the problem?()A. The keyword overload is missing from the command.B. The NAT pool must be defined first.C. An access list must be defined to create static NAT translations.D. The interfaces must be configured for NAT.E. None of the above
考题
Refer to the exhibit. Which command would allow the translations to be created on the router?()
A.ip nat pool mynats 1.1.128.1 1.1.135.254 prefix-length 19B.ip nat outside mynats 1.1.128.1 1.1.135.254 prefix-length 19C.ip nat pool mynats 1.1.128.1 1.1.135.254 prefix-length 18D.ip nat outside mynats 1.1.128.1 1.1.135.254 prefix-length 18
考题
查看静态NAT映射条目的命令为()
A.show ip interfaceB.show ip nat routeC.show ip nat statisticsD.show nat ip statistics
考题
阅读以下说明,回答问题1至问题4,将解答填入答题纸对应的解答栏内。
【说明】
某公司上网用户较少(约50台上网机器),因此公司网管申请了公网IP地址(117.112.2.101/30),拟通过NAT方式结合ACL提供公司内部员工上网,公司内网IP地址段为192.168.1.0/24。
该公司的网络拓扑结构如图3-1所示。
【问题3】(6分)
为实现该公司员工通过出口设备访问互联网的需求,必须在路由器Rl上配置基于端口的动态地址转换,也就是PAT,请解释或完成下列配置命令。
.....
Rl(config)# ip route 0.0.0.0 0.0.0.0 s0 // (12)
Rl(config)# access-list 1 permit 192.168.1.0 0.0.0.255 // (13)
R1 (config)#ip nat pool public 117.112.2.101 117.112.2.101 netmask 255.255.255.0
Rl(config)#ip nat inside source list l pool public // 定义NAT转换关系
Rl(config)#interface (14)
Rl(config-if)#ip nat inside
lRl(config)#interhce (15)
Rl(config-if)#ip nat outside // 定义NAT的内部和外部接口
......
Rl#show ip nat transWions // 显示NAT转换表
Rl#show ip nat statistics // 显示当前NAT状态
Rl#write // (16)
Rl#reload // (17)
......
