Every time learning from you i am finding something new, doesn't whatever i have learned in Cisco so far. Its the way you are making it so easy for all. We love you Keith :)
Still I don't get that idea of the ip address pool for the outside interface. It is assigned the ip addr 192.168.1.5 as we saw at 27:04. So when doing NAT, does it change its IP address dynamically?
Thank you for the question. The pool represents a range of addresses that can be used by the router with NAT. So even if the interface has the IP address of 192.168.1.5, if using NAT, (not PAT), the router will dynamically identify when packets need to be translated from Bob's internal IP (using source dynamic NAT), select an available IP from the pool and use that IP for the translation for Bob's computer. If another computer, Lois, sends a packet through that also needs to be translated, the router will select another (different) IP that is available from the pool, and use that one for the translation for Lois's computer. All the this time, the router will still use it's own IP address for it's own communications AND it will use the translated address for Bob and Lois ONLY when the router is forwarding packets on behalf of Bob or Lois. Let me know if that helps, or if you have other questions, and I would be happy to assist. Catch the whole CCNA playlist here: ogit.online/sloth Thanks again, and happy studies.
@@KeithBarker TOP answer, thank you very much! Keith, I can't thank you enough for giving us these tutorials. They make learning a breeze even if I have hard times going through the books. And yes, I want to become a very good network administrator, want to enable people to communicate and solve problems. You are part of the solution, thank you so much!!!
@@KeithBarker inside local inside global outside local outside global NAT You can explain me Static routing is our job on machine? Dynamic routing is job of machine?
sor sir you hv confused me concering the pool you created what i know is that it should hv a public ip address and not private ip address,pliz elaborate to me about it
Thank you for the question Tunga. The pool represents the addresses we can use for dynamic translation. They don't have to be globally routable addresses, but they are on the "outside" of the network from a NAT perspective. I added another NAT related video in the playlist last week also that may help. Here is the playlist ogit.online/sloth Thanks for watching, and happy studies.
I am a bit confused in the term " inside global, inside local & outside local, outside global". Could you please explain a little bit more in detail. pls
Thank you for the feedback shocker147! I see and hear your point. Will make a note for future NAT/PAT videos to leverage Private on the inside, and Public on the outside. I appreciate the feedback.
thanks for video.for me ask why i nat 1 address static in nat static one to one but all address can connect to the internet.i show nat table only 1 address nat.please help me
Thank you for the question Sơn Nguyễn. When implementing a NAT translation, we can allow a thousands of internal addresses to map to a single routable address. That technique is referred to as PAT, Port Address Translation.

Thank you Gulab! I appreciate that very much.
I have tried to understand NAT for a while now and this has simplified it.
Thanks Keith!
A man full of positive energy.
Thank you Lo Lo!
Thank you, Keith. You are good for the earth. Love you.
Thank you firminorules!
Thank You for the video. I had a doubt regarding nat pool, and this video helped me understand the concept better.
Always love to learn concept from you Keith
Thank you Sameer
Wow! Complex stuff yet a simple explaination! Thank you, Keith! For this amazing Stuff!
This video does not have enough likes. Thanks for the depth on the video I understood nat however is great to see it don
I appreciate that!
This really helped me out alot, thank you!
No problem!
Have a nice day 😊
Thanks for the visit
"Thats the Story and im sticking too" x-DDD great save :-DD
Glad you enjoyed
@@KeithBarker Big THX for the VIdeos Keith. Realy Helpfull.
Yes keep the round picture!
Awesome! Thank you for that feedback, I will. Cheers.
I agree, maybe its because I'm so familiar with Twitch.tv but having a box (of any shape) with the cam footage helps me stay focused/engaged.
Thank you!!!
Whenever I search for something related to networking I append Keith Barker to it

@@KeithBarker I'm beginner for understanding concepts I am getting ideas with you
@@KeithBarker inside local inside global outside local outside global NAT
You can explain me
Static routing is our job on machine?
Dynamic routing is job of machine?

Avinash thanks for your input! That is definitely in my queue. I will be including that in a future video or live stream. Thank you for the question.
Inside (Your Network) Outside (Another Network)
Local (Private IP) Global (Public IP)
Inside local = Local IP
Inside Global = Public IP of Your router (taken from ISP)
Outside local = someone private IP
Putside Global= someone Public IP
Extremely confusing for people new to networking when you use private addresses for public purposes and vice versa.

"Dear Mr Router..." lol
Thank you voiceofreason314!
I need more example of the NAT
Thank you Leku. Will have more on NAT/PAT. Including examples. Let me know if there are any other specifics you would like to see. Thanks.
I want to try this with my Cable internet so I'm going to have to bridge the modem
Sweet
Thank you Glenn.
