And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes
this lab will cover the settlement of firewall any any network.
Well you have many computers or many devices which are connected to a specific servers and then you
and your firewall so that the connection from point A to Point B can be interconnected it can go through
the firewall.
All right.
So we use this software Cisco package for Assad.
You can find it on Google tried to go with it.
And according to your version you can download it either if you are on Mark or on Windows or bomb went
do stuff like that you can travel inside.
So before going into the death let's have an overview of what is exactly the Cisco packets the Cisco
packet transferred is a similar to software that is used for similar switches routers and order networking
devices Cisco devices are genuinely expensive and can not invest in them to test and learn different
topic of networking.
And so you while you downloading it so it's better when you are going to learn sheet to turn off your
Internet connection otherwise you have to look again to net Academy account so that you can proceed.
So we would require to First thing first when you get out range your Cisco packet.
So you have to disconnect from the Internet so that you can continue practicing offline.
All right.
First of all you need to in all in this Cisco certified network associate Academy program to download
it for free of course but since August 2017 everyone can download Cisco packets and that is very very
very nice.
So it is a very powerful software from Cisco.
It is a network simulation software helping student as I said earlier two choice packets and test the
multiple test cases without using any external hardware.
For example here we use different computers from a point B we to go.
So a screech and then we connect and wrote a piece in this piece is this specific P.C. which used for
this settlement for a base of the firewall which has all the properties of the firewall.
So that's why we connect it with the firewall with a new keyboard that cable can find it.
And then it's called consort keyboard.
All right.
So when all B.S. here they are going to this switch they have to go form the switch one and then connected
to the server and then go here I.
If we delay or if we used this connection they will go to the firewall.
So here we have two words.
I mean two ways so that they can go either they go straight forward coming here to you and to the window
is you will.
All they can cohere.
But what we can do we can try to erase distilling and put it away.
So now our computer we will have only one way to go to this whether it is from the firewall.
All right.
So let's go.
It is also helpful for network administrator.
All right.
You need to continue as a guest if you want to download it or if you don't want if you have a net kind
of cut any account you can arrange it while you are online while your internet is who is tweeting is
switching on.
OK.
So some features of it the features of Cisco Packet Tracer letters vision you have precision time protocol
P2P and ADP airspeed a and always in an Internet protocol and Internet of Things.
Internet of Things.
I already put Of course I did need I did.
Improved support for the programming tab added in I O E configuration box javascript and CSA as support
added for Cisco TTP server.
That's very cool.
That's very cool poverty and Cisco packets transfers the following application.
That's what a core manager the HCV.
We will show you DNS.
We will show you an issue TB and or a P O P T N T P S M P S S H telnet or loose guy supported by the
Cisco packet choice.
So you will have Y and downloading that you will have a very good tool for networking penetration in
networking testing or simulation to try to configure your firewall configure your server your computer
without needed any kind of external devices.
Okay so now let's let's just let's go to the practical part just we will not start with with D with
you of course not.
We will go step by step it's this step by step process how how you can do it.
Oh right here.
Just for a quick overview we are on we are timed so as usual when you launch your Cisco packet tracer
you have you would have these things here you have to click on the Smart will like that so that you
have a discrete upgrade to abuse you.
So now here we are going to check all on network.
So we have to network.
This is one network and this this this is one network one network and the waters ease and order network
and d point B is the third network.
All right.
So we click here on this icon message as simple PD you click on it we click on any computer from the
eight planed and then we click on any computer from the B point to see if it will be successful.
Here we are successful sometimes after trying you might see that it is failed at the first time.
Don't be so unaware or don't be so my vote would be so sad.
Just try it again go again cricket and click on any click on any so that it would all.
Sometimes it doesn't work according to the network.
OK so it is simulation how the message get transferred from the a point to the B point is here as simulation.
We are going to try it out and we click here.
So let's see.
So it's not working kids that are working it doesn't block doesn't book by 80 by any by a anything all
right.
So this is how it works.
OK now let's switch over and let's let's start a new project.
You have to click new anyone save okay.
Are you sure.
No I don't want.
All right okay.
Now you have a blank page in front of you.
What you have to do down the page you will see some icons and click on the desktop computer in devices.
Here are those icon and then you will click.
So a disease network devices.
What we don't need this.
We need this one in devices.
So we click on it like that.
And then here you can choose.
We can try to win this thing out.
OK.
So you are going to choose the piece in this top if you want or if you want laptop servers the thing
that you want.
You just choose it.
Okay.
And click on the blank page.
We are to win you there do the same thing to win as many as this time you would want your network to
have.
OK.
To do with the cue.
We could kill again you can click.
You can choose as many as you want.
So let's choose this one.
It should be enough.
Okay.
Yeah.
Okay.
So the next step now next to the end device is icon here.
Here you will find an icon.
Which name is it network devices.
This one as I showed earlier.
Choose it and choose switches on switches.
Exactly.
This one.
So then we will pick up a switch.
Twenty nine sixty.
All right.
So we put an a switch here.
Now arguably you see from this starting point would have to connect the Internet.
Campbell Cooper straight through would be found from the connection.
Okay so let's go to the connection and let's try to Cooper Street.
Look at this one.
Now you're going to win or win all of your stuff here when you did women do.
Ok.
Fast internet which was fast internet and then we're winning it here which is any one of them.
What if only we do it step by step.
Again
fast internet.
They will win it here.
The second one no step by step.
We chose it first and then zero again going to switch move on which was this one.
All right.
So far so good.
I think we do it is just click and drag and you can delete them delayed them.
Yeah.
All right.
So you go now.
The third option is you would have the clinic each switch to a particular router.
Let's say that you have one starting point and one destination.
So you have to have then two switches and two orders.
If every you would want wanted to have its happen.
Okay this busy again swishes here switches it here again.
Same is true the same switch.
Here again we connect them as we did earlier.
Forty point a plus in Tunisia will you will one gain let's return it to the will graphic.
All right so here we go.
Now we have to do switches and we're going to choose also to routers where we can find the waters again
we go to here.
Let's see if we own routers so we can choose this one.
And they could do it or you can eat it but again and again.
And only water will be altered to put it here.
All right.
So far so good.
Then click on your order one to change its property slide with two fingers to right side of the salad
page in the physical tab you will see yellow the green light in a mixer click on it to turn it off.
Then choose from the left side which say W I see.
Let's let's just showing you click on here.
We still later say that this is green.
We have to turn it off turn it off.
Now let's go here.
Oh I.
This one one deed that I see one.
Click here.
And we we need he therefore we can again put it on.
All right.
So do the same thing for the second quarter.
We click and we say to Dwight we turn it off.
Go.
Here we choose this one.
So we need air.
And the black page and black oh yea.
And we need it.
Turn it off.
So we turn it on.
OK.
Now it's a green preference.
All right.
So click the mixer icon again to turn the light on as we have just the wow.
OK.
So now you can connect you to what rose by choosing the CEO DC a cable and single 0 0 when clicking
on your computer to put that cable.
All right.
Since we need a quote We have to go into quotation because it Campbell is a connection that joined to
point a and b.
Which one we have to choose the one that said singular DC is this one.
No.
Is this one.
No.
This one no.
Is this one.
No.
Is this one.
No.
This one no.
You know every thing.
Oh.
Oh then they have do names like Eagle beetle.
So this is a good step.
So we'll tweak it and then we click you.
What we have to choose now not fast internet zero because it's a order.
We need to just choose sealed order and then click and wait here.
Oh I see your.
All right.
Okay so Craig now on a P.C. choose the desktop tab and a B continuation let's step by step desktop IP
configuration so that makes them few changes and what we have to do we have to make our IP address.
We have to take any IP not any IP address but it might be good to put it in a specific range.
All right.
Put something like 1 9 2 1 6 8 and so on and so so that you keep it as static.
All right.
So let's go.
We put 1 1 6 8 1 9 2 1 6 8 and then we can take and then say oh we start from 4 4.
All.
So where do we put.
We don't put one because we just leave it.
We just leave it for a default gateway for what did we.
I mean for the seed.
So as you might see so we can just copy in control C or come and see anybody that be okay.
This is an invalid IP whites that invalid.
Okay.
We we know I should be dead from then.
All right.
It's good.
No one told me this is the scene one one's copy that we make those changes.
Is great.
Now if we have a server we can put the server name here.
But as we are not going into the server for now.
So we lead it.
We let it as a default.
Okay.
So click here and close to do the same thing for all of your pieces.
Again they stop IP configuration and type copying bass.
So we were at folks or would you automatically get it has this subclass and plus the default get right
here.
Great control.
The same again and again.
Six
one.
Okay.
Close go here.
So
now as we we we are now at the B point try because scenes this part is a block of computers.
And then this part is a go of computer.
So let's say that they are not in the same range.
So we can put it e now like instead of one.
So we can board.
That's a DCD then and we start again at full C form.
Okay.
So the scene now is the only one.
So it would ten days is exactly how it would look.
All right.
So we copy the seed because we really need it for the contribution of the next device.
So we go here.
This thing direction.
Yeah.
And I use that as well.
Okay.
Copy.
Yeah.
So we cross it now very good
when you are done with your P.C. with all of them click on a router then choose the commentary tab.
So when I try to click here
OK.
Now we click on conflict tab.
Then right after we have to go to the CBO numbers you see our number you see our number is is 1 0 2
0.
Okay.
Now put the clock weight to something like let's say let's say that it is on 2 million.
If I'm seeing it right.
Okay.
So we put it like
one hundred twenty eight dollars.
Anything like that.
And so where and then is IP address mostly different as the computer's address.
All right.
So put it like something.
1 1 9 2 let's say 1 9 2 1 9 2 1 6 8.
And it's neat to see on which side we have this anybody that I know I could feel it yet.
OK.
Let's see 1 4.
It was 1 OK.
So we can put it like
one 1 these days and then let's say it's see on to an unexpected three in here.
Then one one day.
And had to do this that was one that was on.
Okay so and close it do the same thing for all of your photos.
It depends on how many waters you you have put on your network.
So we have only to do so we have to go and do something for you on it for the owner and for the only
one.
All right.
So let's check again output OCD.
OCD one do all of us Ed you used to be do.
All right.
You're gonna say take in a good moment.
We have to check this one.
I need you Stan.
Okay.
Then let's go back.
You know or convened that go here do the same thing.
So what kind of theme I put there.
You would not try to put it on one me eight injuries one to one saves.
It has been on three.
Now let's put it this on the phone.
Okay now let's go here.
So IP address on the seed.
This it was
Seed
1 1.
Okay.
So and what the was click on great Exelon and close it right.
Okay next things you have to do.
So you have to click on on your orders so a different order after clicking on it you're going to try
to go to the common line interface and and type in it to leave the E config.
So let's go right here we've got to go online indifference so here we are.
We are in the global configuration mode since we have config.
And if so we have to take it so that we will leave it.
All right.
So now we have to take IP would IP would be 0 0 0 0 0 0 0 0.
Space we have to put space here.
So we were put into it and then now 1 9 2 1 6 8.
What kind of what kind of seed we had for this one.
It's good.
It is.
Copy.
Copy it is received.
Will you visit yet check it see this see the windows too.
All right.
So let's pass it on so we get an
was it one.
Yep yep yep yep yep.
Good us then me.
And then when I put under invalid input detected in marker.
All right.
Yeah.
So it's not one we have is we these wounds will.
Exactly.
So any any.
And then the IP address.
So this will do it
invalid.
Okay.
Take this one because this is the world.
So we cannot put the same IP wood for it.
Exactly.
So now it's okay.
And then typing it too easy.
So we went into console no default default for a.
What they mean.
They mean that any IP address from the a point from the a planed and then the first the first for the
second for ze will means that any IP address addresses form the second plane in IP address from the
second point being let's say this is B and this is a point all right.
So that's how it is.
Likewise we do the same thing for the single do with the IP would it present the days the seed on which
they would do one or two would do.
He was on.
Okay.
Now you have put it on 3 1.
So this is the base.
All right.
So let's leave the shell now going to the same thing for the two.
So when I go to here.
So first thing first let's check on how it was for 10.
So that means it would be for 1 0.
So we type we to during the global contribution what is it now we can type IP would say it's just past
the comment we have compiled before and here the book for one.
Oh yes.
Is this is this is is your knowledge of be it.
One two three four.
One two.
Okay.
What now.
Each one.
Okay.
All right area.
Here we go.
Perfect.
So we close it.
Get very good now why do we need to do can we test it now.
Absolutely not.
Because the water should have to communicate wheat or sweet cheese.
And this one and this one.
If you had only one would do so and we did so you wouldn't have to connect the switch with the water
and say if I want this switch to communicate with this dress or a click here icon and corporate steward
too and I click on it and I do do I need to hear.
But if I want this switch to belong to this water and this to this water.
So when I have to do is the same is clicking and I create a safety net and don't get here.
Right.
Now when we are at this point what we have to do is Tuesdays came with the same thing
or
when I called well.
So don't forget the gate we here should be the IP the first Internet IP of that order and then the first
etude IP of that would it should be the gateway of these two.
Let's.
Over.
Amount was a hail.
Let's try it.
Okay.
We see the gateway is.
One is then one.
Okay.
We're going to check it out Internet.
It's 10 1.
Exactly.
Oh if you want you can just over a mouse.
And then you would see it then one IP address 1 9 2 1 6 8 10 1 slash 24.
So let's take this one.
The gateway is 1 1 1 1 1 1 should be the same.
1 1.
This should be the same of course.
The Gateway in one way.
Then one.
Perfect.
So 1 1 2 will behave as 1 1.
Exactly.
So let's click on it to make sure it's wide.
All right.
1 1 1.
Now you can try to test your network to see if the connection will match.
So OK let's try to do the connection click here to send messages.
I mean you go to this computer this computer to see we have to check this first successful.
It's chicken only one this one is one success one you do the last one because we don't have many.
So it's a complex view we should all again successful.
So what about to make the connection to the order.
So let's try it out again.
So let's first
this computer do it successful.
So now we might ask.
I want this network to connect these from the a point to connect to the big point to point B.
So okay so it trade but.
What.
OK let's do it for the purpose of this video and then we click on its core here you see.
It's terrific in here.
Put it in think the reason behind this is that these computer cannot which due to this part of the network
because these orders they don't know how to get how to switch to each other you know.
So when the connection start from here and fluently softly it goes to two or switch to here easily.
What we need is here.
This water doesn't know how to call heat because they are not on the same network.
You see they don't know how to get to each other.
What we need to do we have to configure the IP world so that the IP world.
When we say dogs now do we know.
Aha.
I have to go to this world.
I have to go this way.
All right.
So now let's let's start and make it.
We have to click now on the order one.
This is all.
This is always and we have to go to the common light interface see it I away.
So now automatically we are in the global configuration.
This is the global configuration modem.
So we have to exhibit that we can exist existing prisoner preferred.
So now we can type what we want to type in the IP world IP wallet and 0 0 0 0.
As we have said earlier the zoo is a computer it is any computer.
The starting point between space 0 0 0 0 that means a computer from the destination point.
Now we're going to set.
So now we can set the IP of the wonder.
So the IP of the 12 is 1 9 2 0 1 6 8.
And then what next.
The IP of the audit is 1 9 2 1 3 1.
So deceived by the new presenter O K incident
a mistake.
Some students always do or even some potential is by forgetting to put teams in order.
For example they can forget the seed of D and how things are working.
OK.
Let's put things in order for you here.
We have order.
So let's consider it as the first order.
All right.
So what do you do here.
This is represented for us as the first order.
All right.
And then Campbell he might contain in a b d D1 to the order it contains a b b c your IP okay.
So you see your IP
Yeah this one.
And he goes to the router D is an IP address.
This is an IP address and he near who the switch as well.
And here.
OK.
Now every thing that is connected easily keyed to an IP address.
So let's let's type it.
And so Joy we we expand how things is working.
Please say not OK let's do it here.
All right.
So he is 0 to 1 1.
It has an IP address.
Okay.
Now you we have is this silly are you single part of that who do one of your buddies that see young
of the world to see 0 1 0 4 to 1.
And the first internet connection fast internet connection is a wall or who do one food to one.
It's a good one.
One one do it again.
So my future is now on the switch as an IP address.
He right here.
So it is to be switch IP address switch switch switch
and heal from the switch to the P.C. zero.
It has gone out to the edges of the switch.
One is from the switch again and the P.C. to these.
He has an IP address and the cable.
Likewise the third one and the PCC will be seen zero has an IP address you see two
pieces to this one that has an IP address on it put it under NBC do you see two that's an IP address.
OK this is all that we have here.
So far so good but if we want this serial number we can put it away.
Let's control it so that we make this step by step process.
All right.
Now this is our first network now and this again network is to be here again.
What is it.
It is the water serial number now.
Listen closely to it.
You know right.
So let's click here.
So what can be for going into the dip in the water one we can call it the network one.
Just like network one is in order to know it these days forward without this problem.
All right.
So now let's do the same thing for it to do so the CEO has an IP address.
So this is silly on its the
do you do go one on someone produce.
Do you get an IP address.
Wide
look in here.
Again it might have something like
something like what the do you see or hear.
You have something like to do.
You can put it to 50 55.
Oh OK.
Now 55
215 to be doo doo doo doo doo doo.
OK.
So now and this part is to be what you would like.
Okay.
Now what a network with network.
We do the same thing for all network in
right.
So we have order let's say Luke and Nick order is would go to more.
First.
You can try to buy these people it's
work well.
So 0 2 2 what he does it has.
First the first e the last but you good to do it.
It has an IP address.
This port is this port put a switch has an IP address to switch that's an IP address and you switch
who you do this for you.
It has an IP address days or so switch one an IP address and from here.
Do you also switch to now AC to me maybe it's silly for an IP address.
All right let's settle on at work you let's say we will put an IP it's the base 1 in 2 and 1 1 6 8 1
0.
Okay because it's to be the first.
All right.
And it's good on
before.
Each one on this which is all you do is also recorded.
So each one because it is the first one but it's also never mind.
Okay.
So when you just copying past me and then you could tweak it's good I think that's the best thing you
bought for we put.
Here we are.
So this is the 1 2 1 2 1 4 1 5.
Now we are here therefore species 0 is 6 6.
Let's go.
You see two is 7.
This one I mean you seem to use 8 Excellent.
Now it is the same thing for wanted to on it with 2 of course.
It has an IP.
So the IP address can make can be 1 9 2 1 2 8
2.
Now in this law.
All right because here we are on the second network so that's why we put two so that we put them in
order.
So this is exactly all good.
Okay.
So now we are going to copy again and pass it here.
But instead of one we change all bases.
I mean Oh see here we put it like two.
So now we can put these one these these serial of what is this one.
Exactly.
This is 1 9 2 1 6 8 2 1.
Okay.
It would.
It's base here.
All right.
So now we go here.
But again we're going to change this scene from one to two and then now it it is to be to these one.
Okay now let's go to our network here
in on network.
We might be quite the same again but instead of to see we would put a seed is 1 3 and 0.
So we could eat copy so that we don't have to chain you yet again and again.
Right know we're gonna have just copied and pasted it here and change it all when.
But before that we forget to do the basic things we have to save it is if by accident you have to save
it.
Let's going to an S any.
Oh let's try trade.
Try it or let's put it together.
Try it save
it copy paste it you know it used to be one in order to get.
Now we are here in this switch this part so we copy it and then it will be done.
We copy and it do to go down again copy it instead of food we eat again look you see this one is for
this is W and from here to E.
This part is as the very one and here is as we do too.
So when I could get a copy again and their weekly form.
So this is to yeah to to in full this one.
Now P.C. tree.
Oh I know a b is 5 and 6.
So this is exactly how we can configure in a sine and nine feet address for each of your devices.
Note that.
Let me check it for you.
Let's say not Let's put it here.
No know that note that the IBM Joyce that we settle for.
Or would there form he we will be represented for us the gateway.
So I mean the f 0 0 0 1 represent for also presents as the gateway Gateway IP.
It would be accurate.
So this is just we will see that we understand how it is.
All right.
So now let's just make a few configurations so it's not difficult at all.
So okay if we go here
we'll do it okay so we can go to see I I make it all we can what exactly.
So here we are in due to freeze again now since we have setting up everything in order everything that
we have done before was okay.
It was alright but chose to avoid any confusion.
And if fruit you or we could go so that you understand exactly what we meant.
So we're going to make those changes that we have made from what we did to these ones.
All right.
So to do so you're going to click on author so you click on it and either you can choose your command
line interface to write it or you can just go to the configuration it's like it's a problem and then
you're going to make some changes.
Okay.
This is all old news.
So we can change this one to two to one.
Okay.
Now what are we going to do.
We are going to see one.
OK.
Now we are going to change the IP Joyce the first Internet IP address to what we have sitting on.
So what was it.
It was 1 1 1.
Okay so no changes they did.
No we put it on.
Perfect.
So now let's go to or senior or silly all of the way to one.
So this earlier was that CEO of order one is two one.
This one is this.
Here two one.
All right.
So when I'm gone I would see your when this changes.
One two.
Okay.
So we put it on on your seat and I.
You should type no shutdown or no shot.
All right.
So since you click on the here.
So that's it.
And then.
Perfect.
So now we can try to do the same thing for we will do a tool.
OK.
So I work toward Twitter to do that.
So Sylvia King is going to want to tool.
But first thing first.
Let's see if we didn't have some some evil mistakes.
Exactly.
So you know here we go.
So this subnet mask should be fully Syrian.
This alternate is this one to
do
two ups.
Let's see how it's set up.
Okay.
All right.
So now we click on water here.
So we go to config.
Why do you see it on so config.
No Hobson then we're going to put it.
Let's put it like a do do do do.
So this is all hostname and first Internet.
What do so here.
Are we going to do the same thing.
Okay so we are in order to do what you do has to do to as IP address to me.
1 Okay.
Great one this is what we have to change tween 1.
This is for first internet of what you do first.
Lexington N.C. war a war of water 2 excellent 2 1 1.
So you must use these 1 good we say later on that means no shutdown.
Right now we're going to go to our senior Jake Dad.
Why would I be a choice of CEO.
What was it.
Sylvia who do two to do that and she needed to hear it like that.
To do that I changed my game.
And so must was what to too deep to sell and included on it was pretty darn it so we can try to move
again read the news on Oh so you can do and you know it's Gigi's one minute it.
It's it's one
on.
Okay so now we've finished zero order is this but now it's time to just configure this one as we did
it earlier but now it should be much this order so that we can try to be quality
in on its own feet as we configure them so here they stole config PCC walls and go on open season.
Obviously she's a war logs
as see it.
All right so IP address of peace war was one six okay so default gateway one one of course is yes it's
one was good.
Yeah.
One on
equality is
all right.
Same thing though.
Can think address of two towards eight.
Let's try to find this one in Mm mm mm mm mm mm mm mm mm.
Well see we didn't put it this easy.
We meet in busted tail light and change it to five
no known to a six year it's been six oh six Oh
yeah.
Oh you is no one one in seven.
It's chicken yeah.
It's even so still you say one 7 x let's go.
So you do the same thing.
You still confirming and being poor.
You see food see who was 6 2 6 we got six eggs cause in here they stole configure.
You see Queen was funny
to do it.
Here you go.
All right.
So come on here and sign it.
All right.
So now who do you first check for instance.
Let's supervise.
One last time first off.
Okay.
Go.
He'll okay.
It's okay.
You know it this is 0 1 6.
Where is it.
The war is due 1 6.
Okay.
Perfect score.
I'll close.
Close.
You see one is wanted in this one once again.
Let's check in once proof.
You see 2 is 1 8 2 8
1 8.
Default Wait wait wait.
1 1.
Good game.
Now you see for all of these you see for 3 6 6 2 6 different gateway or no no.
If one gateway is 2 1 the same as the order.
6.
Okay okay 2 1 2 1.
Say so.
Check it again see you get to 1 before you gateways.
So this one now for me to be tied to 1.
Okay so now the Constitution is complete.
We can try no 2 2 test or picture or network by clicking on this message icon and from here to here
you have to check this.
I want to see if it's successful it is what let's delete it so that we can try again that we can see
again from this computer this computer successful IT STRAIGHT.
NOW THIS COMPUTER again because we have made in the configuration guys.
So that's why we check it again and again.
And in these two here obviously successful and and is to do it you know because it isn't there would
fail.
All right so so far so good from now.
So we're going to just have to configure the IP world so let's try these first.
The last name.
It was B so this is one and one time here too.
It shouldn't be success one should we find it.
OK.
Delete them OK now.
Now then the task is we have to make your way so that we we see 2 Disorder.
Hey your wallet.
So in that you send the weakest of the messages or the connection to here.
It must be this way.
Well as we have seen earlier because we don't set it up the IP world off of this network.
So if this computer cannot reach this computer so it can just only be here and be here and from here
to here from here to here.
But they get close because they don't know yet they won't.
So as we have seen that weed control squeak.
Or it was already just click here and well we can even see fate so well now we're going to configure
it.
So what we can do it's deleted.
We have to go to war to one and we have to say to him hey you know what man.
I want to go to this destination.
Please make some house so that we can go to it.
So we are in configuration mode so we can take AP Road and stick it out again.
Okay.
And Cupid comments on it.
That means that we are in a good path of tuna.
So we take AP World and then where we want to go.
We want to go to D to a distant network.
So we did did this scene or disconnect with is the network is is the is the third one.
This one is the third one so too easy.
So we're going to stay or we just copy first.
I had it before or wide to zero and then did subnet was 255 255 255 and easy war and clear but we we
need to go to disagree Ah.
So this number was 4.
So we are off to 2.
So euro food 2 was 2 1 not 2 2.
So we placed this again to do and we have to take 2 and then 2.
So now 10 percent of Excel and so where you are now we are really doing the same thing for the water
tool.
Okay.
Close it.
Okay.
Now we click on this will do now.
Creek and we'll go to sea.
I was endure a so that we go to the canoe so that we go to the global configuration.
We take a finger on a finger in case.
Well now we are here.
Now we can contribute.
Now when we are in water to here we need to go to this network.
So we take IP world IP wood and then this network.
This network is so we can just pass it again first instead of one.
It will be one dud.
Zero.
So okay let's check it.
Network 1 0.
Network was 1 0.
Perfect.
Excellent.
So now we want to put the subnet to 5 5 as it was into 1 2 5 5 2 5 5 5 5.
Do not do that as war.
And we are going to since we are here in the world at all we are going to groups to disillusion this
scenario of 4.
One was what it was 2 1.
Okay so now let's just copy.
Let's just play it again and just more if it is 1 2.
Okay now we can present them.
So now your your network must be able to be connected.
So let's close it and got to trade outward.
All right all right.
Now if everything was done properly quickly as we have changed or step by step process we made them
in order so that you understand where is the IP one what is the IP what is there before 6 7 8 and so
on.
So as usual we start from the water then we take the bass as the water it is someone rebranded to see
war and then the next coalition is won the next coalition is 2 3 4 and stuff in stuff like that and
going on.
So that's how we made it.
So now let's let's send a message from the world to what we know to one.
I mean the first B.C. he would click here.
And now we're going to try to say it.
Let's see if you wanna see you
click successful.
Excellent.
Let's try.
Phone on the phone.
Busy too.
And let me put it you know Excel and again.
So now let's meet the communication in reverse.
Obviously.
Let's see if you see one successful exam.
So this is how it works.
So if you want you can go to simulation and you can just get started so that you see how the progress
is made.
You know just wait a little bit.
That's it.
But okay now what if I want to put a password on my order to put passwords so that if you want to paying
someone if you want to go you have to try.
You have to know the password.
So now it's secure or network but before that we are going to show you how you can just ping them in
a timely note.
So yeah.
All right.
So now we can try to just been one of these computers it's here league and stop common bond so let's
say that we will not try to B know which one okay one this is more easy.
Easy one.
OK.
1 9 2 1 1 6 8 1 1 7.
All right okay.
The connection is made.
It's not it's tried to to being b
0 3 5
0 right.
So it is connected to it.
So let's try again because we think that it is time you know we just a mistake.
Okay.
It is okay.
So we can try to being P.C. for it's a and now.
All right.
So this is how it works.
So now we are going to to empower or network I mean to secure it.
So because when your network is opened to any kind of computers it's in that way of course it's in central
core.
So we have seen you know this IP address so that the network knows about them.
But what happens if an attacker added his computer and configure it exactly the same way.
Of course you're going to get the communication too.
OK.
So we have to secure or network so get sick you need.
