EQUIPMENTS AND COMPONENTS:
No Component Quantity
1 Computer 1 unit

5 Server 1 unit
6 Cloud 1 unit
7 DSL Modem 2 units

THEORY:
DSL CONNECTION WITH PACKET TRACER
Packet Tracer (PT) can be used to simulate the internet. To simulate the internet in PT, you need “Cloud PT” as WAN emulation, adding 2 DSL Modem and connect to Ethernet in Cloud configuration. As for the Internet Service Provider (ISP) side, you need 2811 Router and connect to the Cloud by straight-through (ST) cable. Then you need to add one Server to the network connected to ISP Router as a WEB Server. Next, perform the following procedure for ISP Router: a) adding switchport module that will simulate the internet and connected to the Server. b) configure the interface connected to the Cloud
1. Construct DSL network using Cisco Packet Tracer
2. Perform ISP Router Configuration
3. Peform Cloud Configuration
4. Perform DNS Server Configuration
5. Perform Configuration for DSL Modem
6. Perform Home Router Configuration
7. Perform PC configuration for Internet and Email users
8. Perform WEB browser for web page simulation and verify the connectivity of all
devices

4. Perform “Cloud’ configuration Click Cloud Click Configure tab Pick ‘DSL’ in “Connection”: add “Modem 4 and Modem 5’ and choose “Ethernet 6”. Pick ‘Ethernet 6” in “Interface”: choose “DSL”
- Connect straight-through cable from Router 2811(fa0/0) to Cloud (Ethernet 6). 6. Perform ISP Router 2811 configuration:
Click ISP Router Click Physical tab “turn off” the switch Add ‘switch” NW-ESW- 161 Then “turn on” the switch Click CLI (Command Line Interface): you are required to: configure the interface connected to the Cloud set the IP address for the interface. name the Router configure switchport module connected to the server create VLAN for the devices connected to the switch .

7. Connect straight-through cable from Server (FastEthernet) to ISP Router (fa1/0) Then Perform Server Configuration Click Server 0 Click Desktop tab
PC 2 (FastEthernet) to Home Router (fa0/0/2)
13. Continue configure Home Router: a) configure the interface connected to DSL modem b) set IP address DHCP c) set hostname d) create VLAN for the users e) configure the interface for the switchport module f) create DHCP pool for the users g) create access list of VLAN users h) create NAT pool to take the inside address and map to the outside address i) define the inside interface and outside interface Click Home Router Click CLI tab Router>en Router#config t Router(config)#int fa 0/0 //Interface connected to DSL Modem Router(config-if)#ip address dhcp //Acquires an IP address on an interface from DHCP Router(config-if)#no shut //To enable the interface Router(config-if)#exit Router(config)#hostname Home_rtr //To name the router Home_rtr(config)#int vlan 20 //Create vlan for internet users Home_rtr(config-if)#ip address ..IP Z..

- Perform PC configuration:
Click PC Click Desktop tab Choose IP Configuration Choose DHCP Choose Command Prompt Key-in : PC>ipconfig /all Write your observation into table 6. Table 6. Try to ping to VLAN Internet User (Home Router): Table 6. Try also to ping DNS server You would notice that pinging to DNS Server was unsuccessful.
- To resolve the unsuccessful ping, go to Home router to create access list and to configure NAT (Network Address Translation). Home_rtr>en Home_rtr#config t Home_rtr(config)#access-list 1 permit …Network Address Z.. 0.0.0.255 //command of permitted access and wildcard mask
