    Not everyone has Packet Tracer installed, is there anyway for you to dump the output of a show run and then post that up. You'll get a quicker response that way.

    You don't have NAT configured on any of those routers. What did you try before you posted up here?

    Have you read the study material on it? Post up a network diagram and I'll have a look. Plenty of docs on the web that go through configuring NAT. Try it in a simple situation first, then move on to something more complex.

    From the horses mouth -


    http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080094e77.shtml

    If you are studying CCNA you should have covered this / saw it in a book.

    Everything you need for EVERY subject can be found by going to cisco.com here:

    http://www.cisco.com/en/US/products/ps6350/products_installation_and_configuration_guides_list.html

    Also, to the best of my knowledge (and based on my experience), the exams are compiled based on the information in those docs.

    Also - if you dont receive material about this / have it explained to you make sure you ask why not.
