Use the following requirements:
In the NAT configuration, the first bullet point tells you what addresses you will use in the ACL that is tied to nat. The second bullet tells you the range of addresses that you will use in the ip nat pool command. And the third bullet point tells you that you need a static NAT entry for the DNS server.
This assumes you are using the CLI. For the CCENT or ICND1 material you would use SDM to do this via the GUI. I don't know if that's what you are trying to do, but hopefully I gave you a little push, without just giving you the answer.
Let me know if you need more assistance.
Let's start with the question. Do you understand exactly what it is asking for? If so, you might read the following page and see if you can apply the question to those examples. You can post back here if you want us to look it over, or if you are stuck.
