Router Configuration and Network Troubleshooting

The assignment content describes a simple network setup using Cisco Packet Tracer, consisting of two routers (Router 0 and Router 1) connected to each other through IP routing, with a subnet mask of 255.0.0.0. The network design includes DHCP configuration, web server setup, DNS server setup, and firewall configuration. The assignment also demonstrates the use of trace route command to identify network problems and ping connection between client and server. Finally, it concludes that the simple network setup is successfully created using Cisco Packet Tracer, with configurations analyzed in detail.

1. Introduction
My scope of this project is to create the simple network infrastructure. The Network
design is created by using the cisco packet tracer. The Network infrastructure contains the
two routers. Each router contains the Three PC and one server. The network infrastructure
provides the secure network by using the firewall for the server. Each device configuration
will be discussed. The IP routing between the two routers will be configured. The Client PC
ping the own gateway interface and Server PC ad it will be discuss in detail. The network
design has the network problems and it identified by using the trace route command. The
trace route command using the tracert utility to easily identity the network issues. The DHCP
connection will be configured to automatically provide the IP address for the PC. It will be
discussed in detail. The Web server, DNS server and Firewall configuration will be analysed
and discussed in detail.

Network setup
The above network design is done by using the cisco packet tracer. The network
design provides the productivity and security for the network. The Network design contain
the two routers (Scaling networks companion guide, n.d.). These are interconnecting by using
the IP route command. It provides the communication between the two routers. The network
design has the one or more network problems. To identify the network issues by using the
Trace route command. It tracing the network problems. It using the tracert utility to identify
the network issues. The DHCP connection was successfully configured.

3.2 IP routing
The IP routing is the process of transmit the packets from a one host to another host and
is done by using the routers. The IP routing is implemented, managed and operated by the
routers. The routers are easily determined the packet destination IP address and next hop
address. The router using the routing tables to easily determine the next hop address. It
finally forwards the packet to the destination host. It using the routing methodologies of the
IP packets across the IP networks. It includes the practices and methods of classless inter
domain routing. It contains the one or more information includes the IP addresses of the
destination and source devices and packet numbers (Connecting networks companion guide,
2014).
IP routing between the router is shown below.
In Router 0,
Enter the below command in command line interface.
ip route 20.0.0.0 255.0.0.0 10.0.0.0
It is shown below.
18

In Router 0,
Enter the below command in command line interface.
ip route 10.0.0.0 255.0.0.0 20.0.0.0
19

3.3 Ping
Here pings the client own interface (Kenyon, 2002).
20

After, ping the client PC to server PC. It is shown below.
21

Here also ping the client PC to server PC.
22

3.4 Trace route Command
The trace route command commonly using the one or more utility to identify the network
problems. Here using the tracert utility. It is used to easily identifies the network problems.
The tracert command is used to display the packet path details. It determines the IP route to a
destination by transmitting the Internet control Message protocol. It easily determines the
network trouble shooting on the network. It is one of computer network diagnostic tool for
display the packet path and measuring the delay of packets across the network. It has the time
to live value to determine the intermediate routers. It sends the packets with the time to live
values.
23

Here trace the server PC network problems. It is shown below.
24

4. Task – 2
4.1 DHCP connection
DHCP configuration is shown below.
In Router 0,
It is shown below.
26

To check the DHCP connection by using the below steps.
First click the Client PC or Server PC.
Click the desktop and select the IP configuration.
Choose the DHCP.
It automatically provides the IP address for the PC.
27

In Router 1,
Enter the below command in CLI window.
It is shown below.
28

After check the DHCP connection by using the below steps.
First click the Client PC or Server PC.
Click the desktop and select the IP configuration.
Choose the DHCP.
It automatically provides the IP address for the PC.
29

4.2 Web server
To configure the web server by follows the below steps.
Click server and select the web Browser.
Enter the IP address in the URL.
30

4.3 DNS server
To configure the DNS server by using the below steps.
First click the server and select the services.
After click the DNS.
In DNS services,
Choose the DNS service ON.
Enter the resource records as,
Name is www.csu.edu.au
Address is 30.0.0.1
And Save the DNS service records.
It is shown below.
31

After the Enter the DNS server IP address for the client PC and server PC. The DNS server
IP address is 30.0.0.1. It is shown below.
32

Here Activate the NAT connection for each router both outside and inside.
It is shown below.
33

34

Finally check the DNS server by using below steps.
Enter the URL in the web browser.
It is shown below (Oppenheimer, 2011).
35

4.4 Firewall configuration
The Firewall connection is used to provide the secure connection. The firewall is a one of the
network security device that rejects and grants the network access to the traffic flows between
the trusted and untrusted zone. The firewall configuration is done by creating the complex
PDU in the network. It blocks the network traffic between the client and server. It mainly
used to reduce the network problems. It blocks the network traffic by creating he complex
PDU in the network.
To create the PDU by enter the,
Destination IP address as 10.0.0.10
Source IP address as 20.0.0.11
Sequence Number as 2
One-shot time is 2 seconds.
It is shown below.

5. Conclusion
The simple network setup is successfully created by using the cisco packet tracer. The
simple network design contains the cisco network devices like cisco switches, cisco routers,
cisco server and PC. These are connected with each other. The cisco network devices are
used to reduce the operational and business costs. The cisco Router, switch and PC
configurations are successfully configured and these are analysed in detail. The Client and
Server Ping connection is successfully done. The client pings their own gateway and server.
The network problems are easily addressed by using the trace route command. The trace
route command using the more than one utility to address the network issues. The DHCP
connection also successfully configured and analysed. The Web server, DNS server also
configured successfully and discussed in detail. The Firewall also configured. It provides the
secure connection for the network. It easily blocks the TCP traffic between the client and
server connection.
