Implementing TCP/IP Interconnection in a Network Environment

This assignment details the creation of a network using Cisco Packet Tracer, focusing on TCP/IP interconnection. The solution involves configuring two routers, one for client PCs and another to connect to servers. Three servers are configured with different services, including DNS, DHCP, and web services. The assignment covers the configuration of PC interfaces, server settings, and router configurations, including IP address schemes and routing commands. It demonstrates ping tests to verify connectivity and utilizes the traceroute command to trace data packet paths. The network service configuration includes setting up DHCP for IP address allocation, configuring a web server with forward and reverse DNS mapping, and implementing a firewall to control network traffic. The assignment demonstrates practical network configuration and service setup within a simulated environment, providing a comprehensive overview of TCP/IP network implementation.

INTERCONNECTION WITH TCP/IP
Executive Summary
Cisco packet tracer is used for the creation of the network according to the requirement of the
assignment. Two routers are used for one for connecting the client PC and another for connecting the
servers. Three servers are used and different configuration such as DNS, DHCP and Web service are
configured on the server and the connectivity is tested by pinging the client interface with the servers.

Router 1 configuration:

INTERCONNECTION WITH TCP/IP
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 192.16.1.1 255.255.255.0
Router(config-if)#
Router(config-if)#exit
Router(config)#interface Serial0/3/0
Router(config-if)#ip address 192.16.2.1 255.255.255.252
Router(config-if)#exit
Router(config)#ip route 192.16.3.0 255.255.255.0 192.16.2.2
Router(config)#exit
Router#
%SYS-5-CONFIG_I: Configured from console by console
The configuration of the router is done in cisco packet tracer and a proper IP address scheme is
used for the configuration of the interface of the router. The above commands are used for the
configuration of the router and for the interconnection of the two routers the IP route command is
used.
Router 2 configuration:

INTERCONNECTION WITH TCP/IP
Router>enable
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int Serial0/3/0
Router(config-if)#ip address 192.16.2.2 255.255.255.252
Router(config-if)#
Router(config-if)#exit
Router(config)#int FastEthernet0/0
Router(config-if)#ip address 192.16.3.1 255.255.255.0
Router(config-if)#
Router(config-if)#exit
Router(config)#ip route 192.16.1.0 255.255.255.0 192.16.2.1
Router(config)#exit
Router#
%SYS-5-CONFIG_I: Configured from console by console
The router is configured with the above commands for allocation of the IP address to the fast
Ethernet port and the serial interface of the router. The routing table can be fetched using the command
ip route and the path used for sending the data packets in the network can be obtained using the
command.

1.3. Pinging the network from the client end
Ping the client's own network interface

11
INTERCONNECTION WITH TCP/IP
Ping the local router gateway interface
Pinging the remote router interface
Pinging the server

12
INTERCONNECTION WITH TCP/IP
A ping test is performed between the PC 0 and the other devices connected in the network such
as the interfaces of the router and the servers connected in the network. A successful ping is received
and thus it is proved all the configuration done in the router device works properly.

1.4. Traceroute command from the client to the server
The tracert command is used for finding the path used by the data packets to reach from the
destination to the host address.

Task 2- Network service configuration
2.1. DHCP
The above screenshot is given after the configuration of the DHCP server for allocating IP
address to the PC connected with the interface of the first router.

2.2. WEB Server
The above screenshot demonstrates the configuration of the web server with the forward and
reverse mapping and assigning of the IP address to the URL.

2.3. DNS
The inverse and the forward mapping of the IP address is demonstrated in the above screenshot
2.4. Firewall
Router 1 Configuration:

17
INTERCONNECTION WITH TCP/IP
Router(config)#access-list 100 deny tcp host 192.16.1.2 host 192.16.3.6 eq 80
Router(config)#access-list 100 permit ip any any
Router(config)#int fa 0/0
Router(config-if)#ip access-group 100 in
Router(config-if)#exit
The above command is used for denying the PC with IP address 192.16.1.2 to communicate with
the web server. The router is configured with access list for denying the host to transfer tcp protocol.
