    Pieter, you have a gift for teaching. Please consider making more videos. I've been learning CompTIA Network+ Objectives for the exam and am brand new to networking, and your teaching style and presentation is perfect. The visuals are super high quality and helpful. Thanks for doing what you do. Your materials are some of the best on the internet.... but you need more videos! Lol

    I've been having trouble understanding NAT and your video is what did it for me, thanks a lot! I had trouble realizing that private IP addresses can be reused on different networks, something I kind of already knew, and understanding how the router knows which device to send the packets to. You explained it wonderfully

    Also these videos are exceptionally well structured and your voice is very clear.

  • @seetsamolapo5600
    @seetsamolapo5600 ปีที่แล้ว

    Please make more videos. This was hands down the best explanation for NAT
    Don't mind me just making myself some notes here:
    -There are more people available who even use more devices than there are IPv4 addresses
    -Local machines in a local network are all connected to a router, which is in turn connected to the internet - external public networks
    - To reach a public server, the packet from a local private IP has to go through the home/local router. Then through the internet - multiple routes. Then finally the webserver.
    - The home router changes the packet private IP source address into its own public IP address
    - The home router also creates a NAT forwarding table which helps with return packets to know which packets go to which host in the local network by mapping host's private addresses to reserved public addresses in it
    - The web server creates a response packet with it's destination as a the home router which is a public IP
    - At the home router the packet's destination IP address is changed to the corresponding/matching local private IP address on the NAT forwarding table. Then the packet will be forwarded to the local host
