  1. Hello Rene,
    Great video. I have a suggestion please. Can you start doing like a CCIE video series, many people understand better with videos and the way you explain topics is very great and straight forward, i hope you can implement this idea which will be so great. thanks

    Ammar,

  2. Hi Ammar,

    Glad to hear you like it. About the videos, I will. My goal is to have a video for each of the tutorials I have.

  3. Hello Rene,
    That would be perfect. People like videos and prefer them more that going through books haha , i am looking forward for the videos. Thanks

  4. Hi Rakesh,

    PAT means port address translation, this doesn’t mean that the source port is always changed though. Take a look at this example:

    How to configure PAT on Cisco IOS Router

    Look for the show ip nat translations command in that lesson. You can see the source ports remain the same, the router will only change these if two hosts happen to pick the same source port number.

    CGNAT stands for Carrier Grade NAT. Some ISPs don’t give their customers public IP addresses anymore but private IP addresses. The ISP will use NAT/PAT to put many customers behind a single public IP address.

  5. Please explain what is a bidirectional NAT
