If you want to help your Sister, Parents and yourself then you must do one thing at a time.

You can't do everything at once.

I think if you want to get into networking as your job then YOU MUST do a basic course or self study the N+.

You are trying to learn too many topics at once and are confusing yourself, stick with one topic untill you really understand the subject then move on to the next topic.

So if you get the N+ book read the first chapter untill you understand EVERYTHING in it then move on to chapter 2.

you forgot two things here

1- lack of money
2- i have a thesis to do and my subject is ipv6 AND I HAVE TO DELIVER IT

 

you can self study for the N+, you must be able to afford a book.

And if you have a thesis to do why are you on the internet and not doing it.

You must be able to get some research or do some for your thesis.

 

because my only research source is internet!

 

is there no such thing as a library near you?

They have these things called books in them, they have information in them.

 

maybe in my school!

i have to overcome NAT question for going on my thesis study

wait a minute and i will ask it with a picture

 

The NAT question has been answered for you, the reason you are not realizing this is because you don't fully understand the concepts of what you are learning.

Anyone can pass an exam or course but the real skill is understanding the concepts and being able to apply those concepts in real life. But if you don't fully understand those concepts then it will end in failure for you.

I am sorry to say this, but the internet is not your only source of information you are being lazy, you can go to a library and read some books, you can ask other students and teachers at the school you attend etc etc.

 

wait now it is ready





regarding to this pic , think i am using the one of the computers of graphics dept. , and as you see
there are three different locations connected each other(westfield , eastfield and northfield)

1-considering this pic , can't i use NAT in westfield router cause link between westfield and others
shows public area and we have to protect our internal network from others ?


another pic is coming





here , accounting computer wants to reach internet , should i use NAT and if where ?

also due to this pic , assume human resources server is another place , should i use NAT ?

2-what is internet exactly ? other than branch offices of a same corporation other than
different continental offices of a same corporation ?(for example cisco san francisco and cisco
istanbul)




.............

3- am i able to use more than one router in a same building ?

 

WHY are you not listening to any advice?

WHY are you doing a thesis on something you know little about?

WHY wont you realize that you do not know as much as you think?

 

WHY do you bother GBL?

 

I like to help.

But I am having seconds thoughts on this guy he just wont listen.

 

Kobem,

Was NAT / ip v4b / ip v6 not covered at all in your course or was it totally CISCO relating and did not mention any fundementals of networking at all?

 

I see no point in using NAT in the published diagrams.

http://en.wikipedia.org/wiki/Internetworking

See this page and look where the wikipedia guys point you for references..

See a patern emerging?

 

why not?

in the first pic , i am a user of graph.dept. and i want to reach internet for example google?

in the second one , as an accounting user i want to reach internet again! NAT should be used?

 

NO it does not.

 

Holy shite.

IPv6 and you don't even understand the fundamentals of IPv4 yet? You are in trouble Kobem. Since you don't seem willing to take anyone's advice, I'm going to say this once more to you, then not reply to any more of your posts.

You will never, ever work in this industry if you don't know the basics. NAT is NOT a basic concept! You are wasting your time trying to understand it without having a grasp of more simple elements of networking. We have advised you on here to buy a book on the N+ exam - there are decent ones for about $40 - which surely cannot be out of reach - if your parents are both teachers then they must be able to lend you the money to buy one book! Buy it - read it cover to cover. Even if you don't subsequently take the exam, you will at least have learned the basics of networking. Trust me, when you have, the rest will be so much easier for you to comprehend. Don't get me wrong - I'm not saying any of it will be 'easy' - but trying to learn advanced concepts when you don't know the basics is like trying to drive a car when you can't reach the pedals.

 

I think this sums up how much kobem needs to go back to basics... if he doesn't know what the Internet is... then I honestly can't see how he can learn what NAT is. That's like trying to drive a car without knowing what the road is for.

Sorry, kobem. I love helping people, but I cannot help people who refuse to help themselves. Get a Network+ book, study it completely, then I will again be willing to answer questions.

 

But there is no internet shown on your diagrams. If you want the networks to access the Internet then you will need to use NAT, as the addresses you have used are not routable on the Internet.

Harry.

 

Even the cisco course covers NAT, but I hevn't heard of ipv4b just ipv4.
