1

00:00:00,168  -->  00:00:04,774
In the previous section, we already learn
about standard access list.

2

00:00:05,048  -->  00:00:10,460
Next in this section, we area going to learn about extended access list.

3

00:00:10,955  -->  00:00:15,517
But before that, we are going to learn about web server first.

4

00:00:15,947  -->  00:00:21,091
For example, when we access facebook.com from
the browser,

5

00:00:21,209  -->  00:00:25,006
actually we access the facebook server in the internet.

6

00:00:25,684  -->  00:00:33,544
So here we will configure this server so we can access it from the browser in the client or pc.

7

00:00:33,984  -->  00:00:45,257
Let’s start, open server 1, service, here
we can see http. Http is a web server.

8

00:00:45,726  -->  00:00:55,741
And https is the secure version of http, so this is also web server. Here we can see that

9

00:00:55,741  -->  00:01:04,902
by default, http and https is already on,
so actually, the web server is already active.

10

00:01:05,567  -->  00:01:14,881
Next, we also able to change the display of the web server, here we can edit index.html.

11

00:01:15,533  -->  00:01:29,312
Let’s change this. Welcome to Server 1,
save, yes, okay we have done on server 1,

12

00:01:29,807  -->  00:01:40,063
Next let’s also change the display of server 2,
go to service, here http and https is already on,

13

00:01:40,493  -->  00:01:46,451
let’s edit index.html, change it to
Welcome to server 2.

14

00:01:52,018  -->  00:01:55,110
Let’s also change the display of server 3.

15

00:01:55,501  -->  00:02:06,221
Go to service, http and https is already on,
and then edit index.html, let’s change this

16

00:02:06,221  -->  00:02:08,680
to Welcome to server 3.

17

00:02:12,878  -->  00:02:20,481
Now let’s access the web server from pc.
But if you remember, now we have access list

18

00:02:20,481  -->  00:02:24,580
on router 2 that only allow from vlan 30.

19

00:02:25,102  -->  00:02:30,176
So vlan 10 and vlan 20 will not able to access
the server.

20

00:02:30,646  -->  00:02:41,857
Let’s unassign the access list first, here
we already in fa0/0, copy the command, no

21

00:02:41,857  -->  00:02:43,919
and then paste the command,

22

00:02:45,000  -->  00:02:52,750
Now let’s ping from the client to the server,
vlan 10 to server, failed, test again,

23

00:02:54,210  -->  00:03:06,474
okay still failed, fast forward time, test again,
okay this is success, vlan 20 to the server,

24

00:03:07,191  -->  00:03:12,364
success, vlan 30 to the server, also success.

25

00:03:12,925  -->  00:03:17,183
Now let’s try to access the server from
web browser.

26

00:03:19,504  -->  00:03:26,199
Put the ip address of the server here, let’s
say we want to access server 2, the ip address

27

00:03:26,199  -->  00:03:37,134
is 192.168.1.20, okay here we can see that
we are success to access the web server of server 2.

28

00:03:37,678  -->  00:03:42,700
But here we use http, this is not secure.

29

00:03:44,212  -->  00:03:49,371
If we want to access https, we can use https
here.

30

00:03:49,854  -->  00:03:58,313
So https:// and then the ip address of the
server, let’s say we want to access server 1,

31

00:03:58,535  -->  00:04:02,206
so here 192.168.1.10,

32

00:04:04,904  -->  00:04:06,912
Okay this is success.

33

00:04:07,603  -->  00:04:19,848
Let’s also try to access from vlan 10, https://192.168.1.30,
this is server 3.

34

00:04:24,476  -->  00:04:26,979
Okay this is also success.

35

00:04:27,488  -->  00:04:30,902
Okay so now we understand about web server.

36

00:04:31,267  -->  00:04:37,104
I think enough for this video, in the next
video, we are going to learn about extended

37

00:04:37,104  -->  00:04:38,414
access list.

38

00:04:38,609  -->  00:04:42,023
Thankyou for watching and see you on the next
video.
