  3. Hi Rene! Great Lesson. Just wanted to point out a typo that may need to be fixed. In the beginning of the lesson I think the webserver IP is supposed to indicate “192.168.1.2” not “192.168.2.2”. Please see below:

    “Above we have a webserver using IP address 192.168.2.2 on our internal LAN. The ASA is configured so that IP address 192.168.2.220 on the outside is translated to IP address 192.168.1.2. This allows users on the Internet to access our webserver.”

  4. Rene, you are doing a great job. A very difficult topic explained in simple way.

    Just to add, one reason why we need hairpining is that there are some applications in the DC which need to create control channels on the public IP in order to communicate hence they need inside to inside NAT.

  5. Hi Rene,
    Seem picture mismatch with config , OUSIDE IP for Webserver is 192.168.2.220 or 192.168.2.200

    object network WEB_SERVER
    nat (INSIDE,OUTSIDE) static 192.168.2.200
