Original subtitles

Hi Dad.

This might have that here again.

So in this lecture, I have to show you how you can connect the Mac Decryptor to the internet and also

how to connect my computer, which is behind this micro decryptor to the internet that I'm going to

show you how you can make the upgrade for the process, because as I said, that there are various SD

firmware or SD operating system of the mechanic router board.

So what we need to do is we have to always upgrade their approach to the latest version because migrate

the engineers every couple of weeks they release a new version to fix the box that are or they were

on the old version.

So that's something we are going to do in this lab.

So the dislike, the first measurement we can do is to upgrade to the latest version.

But first we need to connect the micro decryptor to the Internet.

As you can see here, we have a lab of eight bones.

Before I start doing those bones, I will go to the lab scenario to show you what is the scenario.

Then I would come back to the points.

I start going down.

So this is my laptop and I do have a microcontroller which is D AC like I would call it throttle one

which is connected to the internet on its interface, Ethernet one on you connect to I'm connected to

my computer.

So the idea here is that I want this router first to get Internet.

So I need to enable the IP client on the interface Ethernet one because on the internet here or the

ISP actually there is my home router sitting over here which is connected to the Internet.

So this charter has there should be server and there should be is dynamic host configuration protocol.

That means it gives you IP address.

So the subnet mask, the gateway, the DNS and more information, give it to you dynamically without

you put it statically on the interface.

Then as the is said, there should be server and we make this one as there should be client.

Then Ethernet WAN will get an IP address subnet master rather than was then rather one would be able

to go to the internet.

Then after that, we'll have to see how and what we need to do to allow the Internet to be shared from

this router to this computer.

So if you already know about those steps, please skip this part because those are very basic things.

But if you are new to migrating, that is a very good lesson.

So I can show you how you can share the internet from the router out, of course, how you can get the

internet to the router.

So once we do all of this, I'm going to upgrade the router OS.

So the router AOS, which is the operating system that is running inside the microchip rather.

So I have to see what version it has now and how we can upgrade it for the whole course.

I'm going to use the latest ROTHERT OS, which is version seven.

You may have heard that version seven.

We are now in a March 2022.

So version seven, it's already on the stable version.

So I'm going to make all this course based on the Vision seven and not anymore on the version six.

So those are the steps that we're going to do in this lab.

Let's go now back to the points and start doing both.

Number one, look into the micrograph to show how can we look into the microscope?

Of course, these are topics that we and you will also see them on the MVC and a marketing certified

network associate level.

How to connect to the MICROGRAPHS or whether from the web flag, whether from the terminal, whether

from one box or on SSA style that.

So all of those things we see them on the empty and but for this course I'm going to use one box so

what is when box.

Let me first put the picture so we can follow what you are doing and why I'm doing this.

Lab one box is just a tool which is provided by Microsoft.

You can see it.

I have put it already over here.

So this is the tool that is provided by Microsoft.

You can get it from my click website.

You can just go to the browser, let me open the browser and go there.

So from the browser, just write Microsoft dot com and then from here you have to go to software and

it this one box, you just click on it and get the 64 bit and then you get the file that I have showed

you which is over here.

So let's go to it.

And directly this one box will find for me the micro tick rocker, which is at this moment on version

7.1.2.

You can see this on version seven and it say which charter it is.

So this is the board number.

You can see it over here.

That is the model actually the MAX address, it's IP address.

So I'll connect now from to the MAC address of the Mac, the character on the Mac, which you can connect

to the Mac, you can connect to the IP.

So layer two lastly.

So I'll connect to it.

And here to say to you that you have here the following configuration that is installed by default on

the Mac to Crowther.

So you can see they have made some default configuration.

If you want to leave them, you can say, okay, if you want to remove them, you can say remove configuration.

So you don't have any configuration on the microcontroller and you built up your own configured.

So now we're just logging in.

Let's see what is the next step?

Number one is dump what number?

To check the default configuration installed on the market across all of us.

So we go back to here and we were on this place and we can see here that it has already an IP for the

line.

It has the one protected by a firewall.

So you have the wireless enabled, you have some firewall link.

Now let me take this configuration.

I will say here, okay, now we put password later.

So now if you look inside, for example, IP address, you can see that it has an IP received from the

the pushover on Internet one.

It has an IP on the bridge interface.

So the bridge interface, they put inside of it all those ports.

So all those are inside the bridge interface to be like one virtual interface.

That is my lan actually.

And we have some firewall.

We have them, but did not we have here some filter rules already configured.

So all of those things are already configured by the the counter.

That's when you take the rather out of box.

So that's what you get always when you get the rather out of box.

Now for me, I don't want to have any configuration on the other.

So in the next step I have to show you how we can remove this configuration so we can do the confirmation

from scratch and we understand what we are doing.

So don't worry about what you have.

See, now I understand that you might say, what are those configuration where we did it, everything

we would do, the configuration.

I also have to connect the mechanics out of to the internet and chatted the net to the computer because

as it is now, we are connected to the internet.

You can see my router at this moment.

If I make let's go to the tools.

It's better for go to tools and I go to the thing and I try to think a .8.8.8 you see that my router

is connected to the internet.

Also my computer, if I go to the command line and if I make think to Google dot com, you see that

I'm connected to the internet.

So that's what my could do for you that just give you like you out of box, you put it connected, you

have the configuration and it's done.

But this what we really wanted this secure also.

Not really.

We need to do everything ourself.

So let's see what we have to do in the upcoming path.

Number two is dump number three.

Delete the whole configuration from the router and check if it's done successfully.

Very good.

So let's go to the router again.

Now, as we said, we have already the default configuration here to reset that.

The default without any configuration, we have to go to system.

I would have to go to system reset configuration and you have many options.

Again, those options that are explained on the empty Sienna.

But now what I want is to restart it.

That means I want to reset the router here, but I don't want to get any default configuration.

So what we have received from my config engineers that put the default configuration on the wrapper,

I don't want that.

I just want to have no default configuration.

So that means the outer would have no configuration, nothing.

And then I will say here, reset configuration.

And yes.

So now what's going to happen?

The router is going to be rebooted.

And once it is rebooted, we can log in again and check if there is any configuration on the rather.

You see that the problem now is rebooting.

In a moment we are able to connect and see if there will be any configuration on the rather.

So now I see that the Rather has come back online.

Let's connect to it again.

Connect username is admin password.

Nothing.

I will put now a password.

Let's put one, two, three, four, five, six.

Just I know that this security course I'm using one, two, three, four, five, six.

Yeah, that's only now four because it's a lot.

So please use always a very complex password to be at least eight characters put on.

And at the numbers put on it, there's some special characters like exclamation mark and for example

ADD or the question mark.

So all of those things, it's important that you can do one.

You put the password.

But for now, I put just because I'm going to be connecting to the auto many times.

So one, two, three, four, five, six to make it easy.

All right.

So now if we look to the outer, before we looked for the IP address, we saw IP.

That is nothing.

We look to the IP firewall.

We saw some firewallrules.

There is nothing.

No, not nothing.

So you can see there is nothing.

And the easiest way to do it is to go to the terminal and from the terminal.

So because we should log in again.

But that's okay for now.

And the terminal, if we say export, that's a comment.

So when you say export, it will show you what configuration you have on the router.

And at this moment, you can see that is absolutely not any configuration.

So the router has absolutely a blank configuration on it.

Bulk numbers are reasonable number for now.

We need to start connecting to Microsoft to that.

And that's we have to get an IP address automatically on it.

And that's why from the ISP without including the A.P. and the Gateway.

So that's something I have already explained it to you.

Let's expand it again.

I'm going to make we have actually here a router which is my home.

Rather than having the HTP server, there should be server will provide you IP address, subnet mask,

gateway DNS, A.P., many more information if you want automatically.

So you don't need to put the IP address manually on the interface and do something like Match on the

Gateway and so forth.

So there is a there should be server over here.

Why don't I make the internet one?

I should ask the client to receive this information from the server so we can have a communication.

So I'm going to go to Internet wan make a dash because I but this had two things.

Don't add the gateway and don't add the A.P. Of course, you should always add them.

That's but for now, just to show you some a complex slap.

So to see a letter that if you don't have a gateway, you will not have Internet.

All right.

So let's do that.

Let's go to the router.

Let's connect to it.

Now I have a password.

One, two, three, four, five, six.

And let's go directly to IP.

That should be client.

And I will go to the interface, which is Ethan.

That's one.

All right, so here you say that I want to use there should be client on Internet one.

I don't want A.P. That's what I said.

So I uncheck it, and I don't want the default route again.

You always have to keep those checked, like A.P. and the Gateway.

You should always keep them.

Otherwise you will not be able to go to the Internet.

But just to make my lab a little bit more complex for you, I'm just going to take them out to show

you what's going to happen.

So then I will say here, okay, look in the moment, here we go.

I have received an IP address from the DCP server.

Very good.

So that's the step is done.

But number four is done well.

Number five configured the router as there should be server with a range of 1 to 1 28.0.0 slash 24.

What does it mean here?

So if you go back to the picture now we have it in that one is getting the information from the server

which is on the ISP side.

Actually, that is my home router which is over here.

But anyway, you got the idea.

Now I want that anyone who is on the line over here, my computer, either computer, whatever printer.

So anyone which is connect trying to connect to or is connected to the Microsoft to be able to go to

the Internet.

So what I need to do is I need to make the.

Should be server at this time on Ethernet two because this computer is connected to the network.

Right.

So I want to put an IP address on it.

And that's frustrating because if you don't put it out there, you cannot make this should be server.

And I want to make this voice over on Ethernet to say that anyone connected to it in that to it would

get an IP from the range of one night to 168.0. something.

So 0.2.3.4 and so forth.

Okay.

So that's what I need to do.

So now we have to make the recipe server on Ethernet.

And so my computer will have here would be like a there should be client and, and he will communicate

with the server and there should be server will give him an IP address.

You got the idea?

Let's do it.

Let's go to the router.

I would go to IP address first.

We have to put the IP address on ethernet to unless I had to be from the range of 152168.0. something,

so dot one slash 24.

And I'm going to put it on Ethernet too.

If you don't put IP on the interface, you do not do, which is the line that you would not be able

to make that should be server.

Now I'll go to IP, there should be server and now I want to configure the there should be server on

Ethernet.

So we have to click on there should be set up.

There should be sure interface.

It's an actor.

So that's where I want to make the there should be server on Internet2 on that interface so that it

will check the other space one or two and check that 0.0.

That's fine.

The gateway is going to take the IP that we have put it on.

You can actually see that is the IP that we put it on Ethernet two, which is one or 2168.0.1.

So this is going to be the gateway for the LAN users for the Land PCs, correct.

So now I would say you want to give IP addresses automatically from this range from 0.220.254.

Then I'll say yes, of course, dot one would not be in this spool because dot one is for Ethernet two

of the rather.

Then I would say yes, this is the direct you want to give.

That's fine for me and this the time.

So the IP would be leased for 10 minutes then max and that's it.

So now I have configure the ACP server on the internet to block number five is done.

But number six, configure not to allow this IPC to go to the internet.

What does it mean here?

What is not actually not is network address translation.

So now if we make what we have done already now so at this moment my computer should receive an IP from

192168.0. something.

We'll see that it get from the 0.254.

That is the IP that it would get from the server.

Correct.

Now this computer wants to go to the Internet.

It will go to the router and say, I want to go to Google dot com then there otherwise you it's coming

from which source IP address, then it will see us coming from one or 2168.0.254.

That would say 12168.0. something.

That's a private IP address.

Private IP.

Others are not routing to the Internet that cannot go to the internet.

That's how the Iot to have created the IP addresses.

You have public you have private public IP addresses that can go to the Internet, private that cannot

go to the Internet because they are private.

So there are two ways.

Sorry, you have a private IP address.

You cannot go to the internet.

Then my computer will not be able to go to the internet.

So what we need to do, we have to use the non network address translation.

So we make it on the router and we say I, private IP, others coming to us.

We will translate it to be able to go to the internet which translated to our public IP.

But now you can say, but over here you also have a private IP because you have to have seen that the

IP is 192168 or something.

So it's not really technology related.

That's that one.

That's not the gateway.

So you can say, okay, here also it's 1i2.

So yeah, it's also private IP.

How come the other one can go to do that?

Because again, that is not happening over here on that router, on that routing, that is not happening.

So we have showed on that.

But now let's imagine that this IP here is a public IP.

All right.

Not the private IP.

So what's going to happen?

This comes through here and that is it not that it can go to the Internet.

So it's very important to configure to not how to do it.

Let's go to the rather and from here we go to IP.

We go to firewall not.

And I would say over here, I just think coming from the source or source, not me is coming from the

source and it is having one night to 168.0.0 slash unofficial any IP from this source address which

can be 0.2.3.4254 going out from the interface.

It's an so it's coming from the computer, which is why I don't say the zero or something.

And going out from Ethernet one, which is the one interface and the action is to.

Masquerade.

Masquerade means to do not.

And then I will say okay so now we have did not confident what number six is done.

Ball number seven check if the PC can go to the internet if not, solve the problem.

So let's make a review.

We have ethernet one connected getting IP address from the there should be server of my home router

will have this should be served on the router on ethernet internet2 computer.

We will look at the knock the others and that we have met the not.

So let's see if it's going to work now.

First, let's check if my computer has received an IP of 12168.0. something.

Let's go to the computer and let's do IP config.

Here we go.

He has received 19216820.254 and that is his gateway.

Very good.

So that means that if I think the one I to watch get the 0.1 which is his gateway so he can go to the

router.

So if you send his packet to the Internet, he can go to the wrapper.

There are two word mac not and the router should send it to the internet that I'm able to connect to

the internet.

Let's speak to google dot com to see if I can go to the internet.

If I have been to google dot com, we can see.

Hmm it's not really working.

You can see it's not it's not giving a reply.

Shh.

No, it's not working.

What if we think to edit that, which is a DNS IP address?

On the Internet also.

Good question on both.

Okay.

So there is a problem.

So let's see what is the problem?

And the problem is, if we go back to the router, let's check if the problem is able to go to the Internet

tools, being able to not say no or out to host.

So that is a problem on the road.

What is the problem?

Exactly.

The problem is if we go back to the picture, let's clean it a little bit.

The problem is that the computer is able to send everything to the writer and her author has not.

That's no problem.

But the problem is that the writer doesn't have a gateway to tell him to go to the Internet goal from

your gateway.

As I said, that is not the right gateway at this.

Actually, one, not to say that something will sit in a moment.

So there is no gateway.

And if you want, you can see here on the IP routes, look, there also doesn't have any gateway to

go to the Internet.

And the reason is because remember when we were doing the client on Ethernet, Juan, I said to you,

uncheck the default draft.

So let's check it.

Now we put here, I want default and I want the A.P. Look what's going to happen.

Once we do that, you will receive a default draft.

You see, to go to anywhere, go to 121.23.1, which is the router gateway, which is my home router

one.

I don't want to accept a 23.1.

So now we have Gateway.

So if I try to pink 28.8.8, it is working now if I go back to my computer.

I'm on the command line and I tried to think through a bit later today that it's working.

If I try to think of google dot com, it is working.

So my computer now has internet.

Very good.

Number seven is done and the last point is to upgrade the router as to the latest version.

Again, remember that the router should be upgraded to the latest version because Mike Dick engineers

every couple of weeks they released a new version which is fixing the bugs that are on the oldest version.

So how can we upgrade?

So this is the first measurement to be able to harden your microphone is to upgrade it to the latest

version.

So now how to upgrade it and to check if we have a new or to us at this moment.

My daughter is running on the version seven Pulse 1.2.

You can sit over here.

You can also go to System Resources.

And also you can see that it is Division 7.1.2 stable.

So now if I go to system and I go to packages.

Now what we need to do is to make because we have already internet on the mike the creator as you can

just say, check for updates.

And once you do that, we are on the stable version on 7.1, two, two.

That says you have a new version, which is 7.1 for Charlie.

Very good.

We have a new version.

So all you need to do.

Download and install.

You click on that.

Now, before I do that, I'm going to do it in a moment in case you don't have internet on the mixture

either and you want to upgrade it.

So say we don't have it than that now and we want to upgrade it.

We know there is a new version.

So what you can do, you can look to the architecture name, which is Am I BBC?

You see, that is the architecture name of my mike, the character that I have here.

That is something also you can find it from the system resources.

You can look at it.

It's over here.

I'm IP.

SB So what you need to do, you go to the my ticwatch site.

Go.

And then you go to the software on download over here.

You look for divergence of it from the 1.3 stable.

And these are the architectural names of the Micra crop as you look for this one.

Am I be i should be I you install or you download the main package.

So this main package, you downloaded this do that very fast.

So it's not a very big file.

So this has been downloaded now.

Let's put it on.

Over here.

So it is defied.

It's already on my screen here.

And all you need to do.

You just go to the mike, the Crowder, and you just take that one and paste it over here.

It will come inside the file.

As you can see, it's copy now.

It will come to the file list inside.

All right.

Once this file has been copied fully to the file list, all you need to do.

Reboot your router.

That's it.

That's all what you need to do.

So you have two ways to make it.

Whether manually, like I have showed you.

And now it's already here.

Now you can say system reboot.

Do you want to reboot it after you say yes and then it will be rebooted and having the new version.

Now, let me just make it from, as I said before we go to system and we make it from here.

We have to go to packages, check for update, download and install.

So it's going to download it.

She is downloading now to five.

And he's going to install it.

It's rebooting now after the reboot thereafter will be on the version 7.1 Bond Street.

So now my router is back online and let's go through it directly.

We can go now to its IP address.

That's legacy is better.

We connect.

Here we go, 7.1 on three.

And if we go to the system and we go to resources, we can see that it is showing 7.1.3 stable.

All right.

Very good.

Now, the last thing before we finish this lab, I just want to show you, if we go again to the dot

com website inside the software here you have this a change logs.

So here it will show you.

Let's see if we can find the 7.1.3 what they have.

This one, the released 7.1.3.

They say what they have done on this version.

So what?

They have made a fix.

So you can see them as something for the bridging forward, a series three on the series, fixing the

watchdog timing, functionality and so forth.

So you can see that before you upgrade the version to the latest version, look what fix they have done.

So you can see that if you really want to upgrade it with those fixed, then you can do it.

What number eight is done.

And with this point, I have finished the first lap for this course.

So this is the first section.

So now we have understood how we connect the mitraclip to the Internet, and we have gone through all

the steps that I have showed you how you can upgrade your router OS to the latest version.

So I hope that this lecture was informative for you and also in the upcoming election.
