  1. Hi,

    Excellent article. I especially like this kind of setup because they are rare and enforce us to make our brain work harder.
    I think there’s some kind of typo in the beginning, in the basic configuration of R2. The following line seems to be missing:

    R2(config)#interface fa0/0
    R2(config-if)#no shutdown
    R2(config-if)#ip address
    R2(config-if)#interface loopback 0       <- This one
    R2(config-if)#ip address

    Great article! thanks for sharing.

    I am wondering if there is a real world scenario where you would need to apply Nat on a Stick, specially the second exercise…



  3. Very interesting ; but, I have some questions.

    * Question-1

    I do not see the signification of “PBR” in the lesson ?

    * Question-2

    In the first scenario, the answer is return back by a “Reply” arrow. But, in second and third scenarios, the answer is returned by a “NAT” arrow. What is the difference between “Reply” and “NAT” answers ?

  4. Hello Maodo

    If you notice after the second diagram, it states that any traceroute initiated from R1 to R2 will cause FastEthernet 0/0 to respond rather than going all the way to the loopback interface and back triggering a NAT translation. This is remedied by using PBR.
