Hello everyone might have that here again.
Number four I'm going to speak about the day I should be Renay.
So why we need to have the spirit and why we need to cooperate with our network.
And as you can see we have ten pounds to do that before I start doing those bonds.
Let me just take you to the interview we discussed there.
What we need to do in this time and then we come back to the boss to do them one by one.
So that is our only option.
We have a computer here connected to Ethernet to Router one and we have the the should be Schober.
You can see it's here connected to internet three or router and that means that the computer which should
get the IP address of the day that the show is on another network than the one where the server is because
the PC is on the network of 170 to 16 that want that zero.
And they should be sure it is on one night to say that one too.
That means if the computer wants to get in I gather from the you'd be sure you would send a broadcast
to Router one.
And that's what we call it.
This should be discovered.
So it is sent by broadcast.
And as we know from the network basics that the router stopped the broadcast.
So the router was there for the broadcast.
All you are a broadcast our stuff stop you then it this way if we stop the broadcast the broadcast cannot
continue the to go to the there should be sure.
But in order to stop the communication to be able to get the IP address candidates these are just not
possible.
So what we need now to do we have to create this router which is Router one to make it a the HTP relay.
There should be a relay that means that he will relay the broadcast coming from the PC to be able to
go to the device should be Schober and vice versa.
So because there are only two different in that direction there is a router in between.
Then as I said the broadcast will stop it.
Then we create Ratha want to become a city relay.
And then there will be communication possible between the device to be server and the desolately client.
In our case which is the computer.
Another thing to mention here that when you want to create on the desk the server the pool so full of
addresses that it needs to take the IP lock of hair so it will give an IP from this range which is 170
to 60 in that one the zero slash 24 because the PC when he wants to make complication with the first
router he needs to communicate on this IP address because this router has on this interface once every
two 16 to 1 2 5 4.
OK.
So this is exactly what is disappearing.
You may say OK why I need to have this superior why should I put the router of the day or should the
server somewhere outside my network and another matter that while its all about these apps for example
if a company has bought another company and they want that of the two companies use the same day C-p
server and then in this case the there should be servers somewhere as another network of that company.
Then there is a router in between that the shuttle you can make it a secure day.
So the communication between the day should be light and there should be Schober can happen.
So that is the basic idea of what I'm going to do in this lab.
It's very straight through.
So we have there should be client you have this lay in the middle and you have the DSP Schober the disappeared
which is in the middle is the one acting to have led the broadcast of the DSP traffic to pass from that
relay to go to the there should be server and vice versa.
So now let's go to the lab and let's apply that on the lab and by critics.
Poltava one locally or connected the router name router 1 and put an IP address on it and two of them
to the 16 the 4.
So then me put the picture here and that's why we need to do.
So we have to go to router 1 and we have to put on it and add two and three hours of 172 that 16 of
1 2 5 4.
So that is what we need to do.
So I will go to box now.
That is from box and I'm not connected to that router you see.
There is not any compression on it are connected in like others.
And then I will go to the IP and then others help with the IP address and this is the picture so we
can see what I'm doing once I get to that 16 to 5 for the full slash 24.
And this cannot happen on Internet to.
So that is the first thing I need to do.
But number one is not actually we have still need to name it after one so let me just give him a name
so I got the system identity and then we would make Rothera one here.
OK.
That Bonta done.
Well number two putting the address on it and of one of one I want to say that wanted to apply for and
that IP address we need to put it on it and three or frother want to be able to communicate with the
city relay.
So lets do that.
I would go here to IP address and I would go here and make an IPO of 1 and 2 1 6 1 2 5 3 slush 24 and
it's going to be on internet 3 which is connected to the disappearing date.
And if you want to come up with a comment here connected to the Internet free of router which is the
dish server actually it's actually.
So then would say OK.
And here I will say OK.
All right.
So this is connected to my computer and this one is the IP address that it's connected to the day I
should be sure.
I would say that should be the day it should be should be server because now we are told that there
should be a delay but the one is the disappear.
OK.
What happened to his darn phone number three log into the same router name attracted to him.
So I'll take the cable from the first shuckers and that's the cable from my computer and are connected
to the same router.
So I have Winbox connectivity and I will go to Winbox now again
and from here I will go to this router.
And this router we need to name it we go here to system identity and we name it router to which then
to be the DST for the server number three is done before put on had an IP address of one night to say
that one of the five for slushed metaphor on the interface is unnecessary.
So what we are going to do now we already have.
If you see here on the graph we have put an IP address on this interface or not the one that we need
to put from the same region that is on the interface router.
So the communication can happen.
They can see each other on their street.
So lets do that.
I will go to the router go to IP address and from here I would go to 1 9 2 6 8 1 2 2 5 4 plus 24.
And thats going to happen on its face it in 3D.
Here we can say connected to internet 3 to 1.
And then I will say OK now we need to check if they can see each other.
I would go to the terminal I would say Thing 1 9 2 1 6 8 1 2 2 5 3 that's the I got this off of one
and we can see they are able to see each other.
The being is giving me a reply.
OK.
Very good point number four is done now Point Number five we have to start now configure and it should
be 7 and the day should be today considered a day should be Sherburne Raptors to having a pool of 1
7 to the 16 that wanted zero.
So we go back into the picture and then you remove this OK.
So what we have done now we have just put the IP addresses as it is on the picture and how we need to
configure the server here because that's the server and it's going to be necessary because that's the
one connected to the Router one but it needs to have the range of this right once and through the 16
to one that something.
OK.
Because when the users really want to get in I gather they should get an IP address which is similar
to this ranch which is on it and.
And that's what they're asking us to do.
Let's go to that two.
Start doing the configuration.
I would rather do.
And from here I will go to IP the server and we say that should be set up.
I want to continue the there should be server on it that I see and hear I want it here because only
the message that is this wrencher IP address I will say I want the range of IP or the network to be
once every two to 16 the one.
You.
Be careful to change that.
And then I would say next.
Now they say OK what is the gateway What is the gateway for the users will get.
I gather this from this ranch.
Actually if you looked at the picture the gateway if we looked at picture here on the other one it is
172 that 16 foot long docked to 5 4.
OK.
Because all the users who are here that would go to that interface.
In my case there's only one laptop but imagine you have here a switch and you have many other PCs.
Then they will all go to this gateway which is once and through the system that want to fight for.
And you have to precisely that on the complication that you are doing here.
So let's do that once I'm through the 16 one 1 to fight for and then next.
Now they are asking if the HTP relay is one sent to this you seem to want to fight for.
Actually that's correct.
But I just want to show you how we can said that manity so I'll disable it for now but you can leave
it but for now I will I will disable it.
OK.
And then I will show you how you can change that later.
All right so let's say we don't have any should be a delay and then we say next.
That is the crash it would get from one cent to the 16 that on the phone still the 5 3.
That's fine.
Next the NSF we want to spend today that they play late next.
And this time and finish.
OK.
So we have configured the dish server on a router to point number five is done.
Number six.
Go to the there should be Schober setting and on a relay put the local IP address on Route 1 which is
once and to the 16 that one took the 5:4.
So we have to say to the DCP server that there is a relay OK there is a relay that you have to communicate
with.
And that is if you go to the two here on the doubleclick you can see that this relay over here and that's
what I told you that I will show you how you can put it in my room you could leave it and to be met
on automatically.
But it's better than the app because I prefer always to be Mundial everything.
So you can put it here once into the system to 5 for and this relay here should be the IP address of
your local router.
OK.
So if you go here on the picture we see let me just clear here we'll see that 172 that 16 that wanted
to fight for is this it is for this IP on this interface once into the system the one that the 5:4.
So I say to the to be sure that this is the IP address of the reader the local.
OK.
Always remember it should be the local one connected to the land.
All right.
So here they said that this IP address once to those who seem to want to fight for.
And we have it here wants something that is in the phone book.
And then I would say OK well Number 6 is done.
And with this part number six we have already finished the work on the dash server side.
Now we need to go to the HP relay which is router 1 and we need to do some work on that router.
OK.
Our phone number seven they said to log to router 1 and then we have to go to IAP there should be in
relay then I will take the cable put it on Router one again for all the wonders that disappeared.
They will go to Winbox
and from here I will go to the MAC address.
I'm still going to mycologist because I don't have an ID yet on my computer to be able to have layers
free communication with the boss.
So this has got to be and there should be a relay.
OK Point Number 7 has done whatever it took interface even at to.
There should be sherbert one I don't say that one of the two by four and lock allow that is once and
to that 16 to one.
So what we are here on the domestic PIERI they let me make it bigger.
So you need to go to plus on plus here you have to mention what are they interface or what is the interface
the server.
And of course you have to put the local address so they interface they said here.
It's nice to be doing that too.
OK.
Remember again we are now on the Shippey relay and the reason I do if we go here to the picture is this
interface again it's the local interface.
Remember it's always local.
So we have to say that OK the relay is happening on interface too.
They should be server is the IP of the day should be server that is in communication with the DST period.
So to go back to that picture there should be a relay can communicate with the server on this IP.
1 2 1 6 8 1 vote to 5 4 and would have been good.
Weve seen that you can see it.
OK.
So this is what you need to put here.
Well here we sideslip the server IP which is 1 9 2 1 6 8 1 4.
And the local address here again is the others which is on internet too.
So you can see they mentioned here you have to put once into the 16 that wanted to 5 4 which is this
IP address for the Gap 172 to 16.
1. 2 5 4 1 which is on it and too.
Thats always the local IP.
So lets do that here we want to extend that funding to fight for and then I will say OK.
So that is what you need to do in order for the router 1 which is the DCP right to become every day.
OK.
So first you can figure that there should be summer and you were told to stick this over with your hands
of the day.
And then on the day should be the day you may conflagration that I just showed you now and then in this
way there is communication between the teacher and the DST every day.
Point Number eight is done both Number 9 check if your PC get an IP address from the day it should be
Schober from the pool once and do that 16 that one that you.
So before I do that I just want to make a fresh reminder what we have just made.
So we have created a there should be server on routers too and we said the pool is going to be 1 7 to
16 that one that zero slushed 24.
And we said that the relay is the IP of 170 to 60 and that one to five for the local one here.
Thats what we have done on routers to on Route 1.
We have said that.
Okay I'm going to make the relay on this router and it needs to communicate with this IP address and
we put the relay IP and into place the local one over here.
All right.
And of course we have seen that here that is being replied so being is working.
That means they can communicate to each other.
Now connect my computer here and I want that my computer get an IP address from disport.
OK once I get to the 16 that want that too.
So all I need to say I have to say out of 10 I gather is my on my PC that what will happen the broadcast
will come through here and then have the relay will allow the broadcast for the day should be offer
to go to Iraq to do and then here will be the door that I already explained to you about it how the
convocation of the day should be will happen.
And then at the end he will get and I gather from this pool which is once and to the 16 the one or something
so let's do that.
I will go to my computer now.
So it's already now connected.
I would open the command prompt here.
And I will say IP.
And we don't have IP address so let's do now I can take slush radio and we'll see if we will get an
IP address.
And indeed you can see what I said IP conflicts Russia and you he has received an IP from the ranch
of once and to that 16 the quando 2 5 3.
And that's from the pool.
Who killed the pool that I already written here.
So he has received this IP and to be sure that he has received from this day I should be Schober I can
say I've been configfs slush all then.
Should he be convicted of then we look to the D.A. because I would ask to be able to say that they do
that and you can see if there is there.
OK.
And you can see the distribution over here.
It's mentioned it's 1 2 1 6 8 1 2 5 4.
So that's the only piece of it that is giving out of this to this issue.
And of course this being how it's being to the to the face of it and that two of the one which is 172
is that 16 foot 1 2 5 4 which is get away then you can see he has a glove.
So he is able now to see Route 1 which is the DSP.
They both Number 9 is done so we have seen that he does receive an IP from the pool and then at the
end it's saying keep the same settings on your router for that.
And so that's OK.
So this is what I wanted to show you and this lab.
This is a very important lab.
You cannot really find a lot of information about that should be relied on my critic on the Internet.
So I decided to do this lab just to show you how you can configure there should be a relay on the microphone.
Of course there's another way that they say that you can put the ports to be on a bridge but in this
case when you make a bridge between the port then the function of the relay is not any more there because
then it becomes like a switch.
OK.
So I prefer this way because this way you are making the the real relay and your router will let the
broadcast pass so it's still a router but it is letting the broadcast to pass using disappear.
So that is what I wanted to show you.
And this life I hope that this app was informative for you and I wish to you in the upcoming election.
