Config Lab Challenge 1 (NAT)

September 1st, 2015 Go to comments

Refer to the exhibit. You are tasked to configure Internet access for the users in your company. Your ISP has given you six public IP addresses in the range of 45.9.1.65 45.9.1.70/29 .
Your company has 62 hosts that need to access internet at the same time. They are using private IP addresses in the 172.16.4.65 – 172.16.4.126/26 range.

Basic router configuration has been configured. Your tasks are:
+ Configure NAT on R1 so that all hosts can have Internet access at the same time
+ Configure appropriate interfaces for NAT translation

    @cisco lover: It is not the same way. In the real exam you will click on the Console PC to connect to routers/switches. A window will appear like the Console window for typing commands. You can use this demo link to see how real exam works: http://www.cisco.com/web/learning/wwtraining/certprog/training/cert_exam_tutorial.html

    why is “access list 1 permit 172.16.4.64 0.0.0.63” command not wroking while “access list 10 permit 172.16.4.64 0.0.0.63” is working…

    2. Create a standard access control list that permits the addresses that are to be translated
    R1(config)#access-list 1 permit 172.16.4.64 0.0.0.63

    But, why can’t has been, too.
    R1(config)#access-list 1 permit 172.16.4.65 0.0.0.63, Is this must be funtionality?

    Why yes, or Why no?

    @marco, you can’t use access-list 1 permit 172.16.4.65 0.0.0.63, becuase .65 is not your network
