TCP/IP NETWORKING
PC Configuration
The above screenshot demonstrates the IP address used for the configuration of the PC.
The IP address used for the configuration of the interface of the router is used as the gateway
address of the PC (Wallace, 2014). The IP address used for the configuration of the DNS server
is used for the configuration of the PC with DNS. Here The IP address of the PC is 172.16.1.2
Subnet mask is 255.255.255.0, default gateway is 172.16.1.1 and the DNS server address is
172.16.3.3.
Server Configuration
WEB Server

4
TCP/IP NETWORKING
For the configuration of the web server the IP address 172.16.3.6 is used and the default
gateway is 172.6.3.1 since it is used as the IP address of the fast Ethernet address of the second
router (Nunes et al., 2014). The IP address of the DNS server “172.16.3.3” is used for the
configuration of the WEB server DNS address.
DHCP Server

5
TCP/IP NETWORKING
The DHCP server is configured with the IP address 172.16.3.2 and static IP address is used for
the configuration. For the configuration of the DHCP server it is first configured with a static IP
address according to the addressing plan and a default gateway is assigned using which the
server would send and receive data packets in the network.
DNS Server
The DNS server is configured with the IP address 172.16.3.3 and in the service option the
and DNS service the URL is used as www.gagandeep.csu.edu.au for the configuration of the dns
server.

Router Configuration
Router 1 Configuration
For the configuration of the router the GUI is used and for the serial interface S0/3/0 the
IP address is 172.16.2.1 and the for the fast Ethernet address the IP address 172.16.1.1. It is used
as the gateway address for the network device connected with the fast Ethernet interface of the
network. The serial interface of the router 1 is used for connecting with the serial interface of
router 2 and communicating with the server networks connected with the fast Ethernet interface
of router 2.

8
TCP/IP NETWORKING
Router 2
For the configuration of the second router the IP address 172.16.3.1 is used for the fast
Ethernet interface and IP address 172.16.2.2 is used for the configuring the serial interface for
communicating with the first router interface.

10
TCP/IP NETWORKING
An IP addressing scheme is followed for the configuration of the router and creating
different subnets for sending and receiving data packets in the network. The interface can be
configured using the graphical user interface of cisco packet tracer and the CLI command line
interface can also be used for configuring the interface. The commands used for the
configuration are attached with the report.
Routing configuration on both the routers
Router 1
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 172.16.1.1 255.255.255.0
Router(config-if)#
Router(config-if)#exit
Router(config)#interface Serial0/3/0
Router(config-if)#ip address 172.16.2.1 255.255.255.252
Router(config-if)#exit
Router(config)#ip route 172.16.3.0 255.255.255.0 172.16.2.2
Router(config)#

Router(config-if)#
Router(config-if)#exit
Router(config)#ip route 172.16.1.0 255.255.255.0 172.16.2.1
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to down
Pinging the own network interface from the client PC
A ping message is sent from the command interface for testing the connection between
the client PC and the router configured in the network.

12
TCP/IP NETWORKING
Pinging the local router gateway interface
A ping test is done for checking the connection between the local router gateway
interface and the PC connected in the network.
Pinging the remote router interface from the client PC
The screenshot shows the connection between the remote router i.e. the router 2 and the
PC connected with the router 1 interface. The IP address that is used for the configuration of the
fast Ethernet interface of the router 2 is used for pinging from the client PC connected with the
fast Ethernet interface of router 1.

13
TCP/IP NETWORKING
Pinging to server
A ping is sent to all of the servers for testing the connectivity between the server and the
Pc. The following screenshot are used for the demonstration of the connectivity.

14
TCP/IP NETWORKING
Application of Traceroute from client to Server
For the identification of the network path followed for reaching the server address is
identified using the traceroute command and it returns the time taken for reaching and the hop
address to reach the destination address.

Task 2 – Configuring Network Services
1. DHCP
For the configuration of the DHCP server it is first configured with a static IP address
according to the addressing plan and a default gateway is assigned using which the server would
send and receive data packets in the network. Then two address pool is created for both of the
interfaces and allocate the IP address automatically to the PC.
For testing the DHCP server configuration the IP configuration of the PC connected in
the network is set to DHCP to automatically get the IP address from the DHCP server.

2. WEB Server
The WEB server is configured with the IP address 172.16.3.6 the HTTP service is
enabled in the web server for hosting the website. The screen shot of the configuration of the
WEB server is given below:

TCP/IP NETWORKING
3. DNS
For configuring the DNS server the IP address 172.16.3.3 is used and the DNS service
enabled from the server. The name used is www.gagandeep.csu.edu.au and the IP address of the
Web server is assigned to it for connecting it with the webserver.

18
TCP/IP NETWORKING
For testing the configuration of the webserver the browser is opened on any of the client
Pc and the URL is use for opening the webpage hosted in the webserver. Since the IP address is
used for the NAT configuration the IP address can also be used for accessing the webpage of the
web page (Lee et al., 2018). The following screenshot are used for the demonstration of the
configuration of the DNS server and testing the connectivity between the WEB and the DNS
server.

4. Firewall
The router 1 is configured with the firewall policy and thus access control list is used for
configuring the firewall policy (Briggs et al., 2015). The commands used for the access control
list are attached in the document for blocking the PC with the IP address 172.16.1.2.
Router(config)#access-list 101 deny tcp host 172.16.1.2 host 172.16.3.6 eq 80
Router(config)#access-list 101 permit ip any any
Router(config)#int fa 0/0
Router(config-if)#ip access-group 101 in
Router(config-if)#exit
The following screenshot is used for the demonstration of the proper working of the
access control list. The URL is used in the browser of the PC for accessing the web server and
testing the configuration.
