    - In Part 2, I cover NAT overload translation or PAT, and dynamic NAT using a NAT pool of public addresses.
    - In Part 1, I cover all of the basics regarding NAT and how to configure it for the CCENT and CCNA certification exams. The video demonstrates static NAT translation, and port forwarding.

    17 YEARS ... I've been waiting for a CLEAR... NAT explanation from Cisco!

    Incredible! I was afraid I wouldn't understand NAT and all its features, but your careful instruction, coupled with my writing it all down as I went along, made this simpler to comprehend than I had thought. Thank you!

    Man, I need to up my game with my CCNA studies. For me it's all about retention. I understand the concepts, and the practicum, but you sure make it look so darn easy while I have brain cramps just trying to remember the Cisco commands. You do such a great job explaining your CCNA knowledge.

    i have a question about the bit input the serial interface
    to start, I have ping from my pc (ping 1.1.1.2 -l 1000 -t) on the other router (WAN CONNECTON) and when I'm on the router that I ping him with the show interface serial command 1 / 0 and in (30 second input rate 0 bits / sec, 0 packets / sec) I received only 8000 bits while than the transmission ping contunu (ping 1.1.1.2 -l 1000 -t), but why I always receives 8000 bits and my ping always contunus.

    • @danscourses
      @danscourses  5 ปีที่แล้ว +2

      Did you setup routing> I think I used default static routes in the video so the routers know to forward the packets. Also check that you have the router interfaces configured with ip nat inside and ip nat outside

    are you using a routing protocol or is NAT it's own routing protocol? I'll download the file tomorrow in case you're busy and cannot find time to answer. TY for the video!! great material for sure

    • @danscourses
      @danscourses  6 ปีที่แล้ว +1

      I forget if I used static routes or a dynamic routing protocol. NAT is not its own routing protocol it is typically used only for translating public to private addresses and vice versa when the packets pass through the router

      @TheDave000 6 ปีที่แล้ว

      You are trying to create a standard ACL. This needs to be numbered upto 99. 101 would be an extended ACL, so the command is expecting a TCP/UDP statement. Number it anything from 1-99 and the command will work.
