University TCP/IP Internetworking Report: Network Design and Services

This report details the configuration of a TCP/IP network, encompassing the setup of PCs, servers (including web and DHCP servers), and routers. It includes network diagrams, IP address assignments, and the configuration of router interfaces. The report further elaborates on routing configurations using CLI commands, along with ping tests and traceroute analysis to verify network connectivity. The second part of the report focuses on configuring network services such as DHCP, web server (HTTP/HTTPS), DNS, and firewall rules. Screenshots are provided to demonstrate the successful configuration and functionality of each service, including the blocking of web server access via the firewall. Finally, a bibliography of related sources is provided.

TCP/IP INTERNETWORKING
Task 1 - Setting up a Network
Network Diagram
1. PC, Server and Router interface configuration with proper IP address
PC configuration

2
TCP/IP INTERNETWORKING
For the configuration of the PC it is essential to configure the DHCP address pool on the server
and on the PC the radio button DHCP is selected to automatically get the IP address form the
router.

3
TCP/IP INTERNETWORKING
Server Configuration
WEB Server

4
TCP/IP INTERNETWORKING
The WEB server is configured with a static IP address according to the IP addressing plan of the
organization and it is kept in separate subnet for increasing the security of the network.
DHCP Server
The DHCP server is configured with a static IP address according to the IP addressing plan of
the organization and it is kept in separate subnet for increasing the security of the network.

5
TCP/IP INTERNETWORKING
For the configuration of the DHCP service a start range is selected and the number of user
allocated in the subnet is inputter for allocating the maximum number of IP address to the user
connected in the network.
DNS Server

6
TCP/IP INTERNETWORKING
For the configuration of the DNS server the url www.RaheemAbbas.csu.edu is used and it is
mapped with the IP address used for the configuration of the WEB server such that it support

7
TCP/IP INTERNETWORKING
reverse mapping and the user can either use the IP address of the url to connect with the WEB
server.
2. Configuration of the Router interfaces
Router 1 Configuration
For the configuration of the router the CLI mode of the router is opened and firstly the interface
is selected to inputting IP address to each of the interface. Here the router is connected to the
switch using the fast ethernet 0/0 and thus ip is set for the fast ethernet that acts as the gateway
address for the PC connected in the network and the serial S0/0/0 is configured with with IP
address of another subnet for management of the connection between the routers.

8
TCP/IP INTERNETWORKING
Router 2
For the router 2 configuration the same procedure is followed as the router 1 where the IP
address is inputted for each of the interface and it is activated using the no shut command.
2. Routing configuration
Router 1 Configuration
The router configuration command that are used for the configuration of the router1 are given
below:
enable
configure terminal

9
TCP/IP INTERNETWORKING
interface FastEthernet0/0
ip address 152.63.0.1 255.255.255.0
exit
interface Serial0/3/0
ip address 152.63.1.1 255.255.255.252
exit
ip route 152.63.2.0 255.255.255.0 152.63.1.2
ip dhcp pool dhcp1
network 152.63.0.0 255.255.255.0
default-router 152.63.0.1
dns-server 152.63.2.3
access-list 101 deny tcp host 152.63.0.2 host 152.63.2.6 eq www
access-list 101 permit ip any any
access-list 101 deny host 152.63.0.2
access-list 101 permit any
Router 2 Configuration
The router configuration command that are used for the configuration of the router2 are given
below:
enable

10
TCP/IP INTERNETWORKING
configure terminal
interface Serial0/3/0
ip address 152.63.1.2 255.255.255.252
exit
interface FastEthernet0/0
ip address 152.63.2.1 255.255.255.0
exit
ip route 152.63.0.0 255.255.255.0 152.63.1.1
3. Ping test
Pinging the client own interface
The ping test is done for checking the connectivity of the devices and sending and receiving of
data packet in the network. The screenshot of test is attached withy the report for the
demonstration of the functionality of the network.

Pinging the local router gateway interface
Pinging the remote router interface
4. Traceroute

13
TCP/IP INTERNETWORKING
The traceroute is sued for analyzing the number of hops used by the network for reaching the
destination address. Here the traceroute of there of the servers are used for identification of the
hops from the source client PCs.
Task 2 - Configuring Network Services
1. DHCP:
The configuration of the DHCP server is given in the report which shows that the client PC has
successfully received the IP address and demonstrates that the DHCP server is configured
properly.

14
TCP/IP INTERNETWORKING
2. WEB Server:
The configuration of the web server is demonstrated in the following screenshot which shows
that the HTTP and the HTTPs service is enabled.

15
TCP/IP INTERNETWORKING
3. DNS:
The following screenshot shows the proper configuration of the DNS server by entering the url
used for the configuration in the browser of the pc connected in the network.

16
TCP/IP INTERNETWORKING
The IP address used for mapping in the DNS server is used for reaching the webs server for
testing the proper configuration of the DNS service in the server.

17
TCP/IP INTERNETWORKING
4. Firewall:
The following firewall configuration is used for blocking the access of the web server for a client
pc connected in the network.
access-list 101 deny tcp host 152.63.0.2 host 152.63.2.6 eq www
access-list 101 permit ip any any
access-list 10 deny host 152.63.0.2
access-list 10 permit any

18
TCP/IP INTERNETWORKING
The above screenshot shows that the firewall is configured properly and the pc is blocked from
accessing the contents of the web server.
