Config Lab Challenge 1 (NAT)

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

    Flash Player does not work on browser, I cannot answer the question but the config is:

    interface E0/0
    ip nat inside
    interface S1/0
    ip nat outside
    exit
    ip access-list standard NAT_SOURCES
    permit 172.16.4.64 0.0.0.63
    exit
    ip nat pool ISP-POOL 45.9.1.65 45.9.1.70 netmask 255.255.255.248
    ip nat inside source list NAT_SOURCES pool ISP-POOL overload
    end

    @Fer: This lab is based on Flash but it was retired so we are finding another way to fix this issue. Please ignore these labs.
