Tutorial Exercise 1: Wireshark

In this lab, we'll investigate the behavior of a NAT router. This lab will be different from our other Wireshark labs, where we've captured a trace file at a single Wireshark measurement point. Because we're interested in capturing packets at both the input and output sides of the NAT device, we'll need to capture packets at two locations. Also, because many students don't have easy access to a NAT device or to two computers on which to take Wireshark measurements, this isn't a lab that is easily done "live" by a student. So, in this lab, you'll use Wireshark trace files that we've captured for you. This should be a relatively short and easy lab since the concepts behind NAT aren't difficult, but it'll be good nonetheless to observe NAT in action. Before beginning this lab, you'll probably want to review the material on NAT in section 4.3.3 in the text1.

Tutorial Exercise 2: Cisco Packet Tracer

Introduction
You will submit work in assignment activities during the study period. This is an individual assessment.

In this assessment you are required to prepare a 1000-1500 words abstract in IEEE Style. To prepare the abstract you need to select an article published in 2020 and later. The selected article needs to include networking and communication. The article needs to be on one of the areas given below.
Networking
Communications
5G cellular systems
Ad hoc wireless networks
Internet of Things (IoT)
Wireless Networks
AI Powered Networks and Communications
Wireless LAN
Computation and Data Driven Wireless Communications
Heterogeneous cellular networks
Next generation WiFi and LiFi
The report must follow the marking guide. Please note that citation of sources is mandatory and must be in the IEEE style.

Cisco Packet Tracer (Part A)
Please complete Activity 6 and submit the course completion badge

OSPF and ACL (Part B)
Download the Tutorial 2-Cisco packet Tracer file from the LMS. Open it in the Cisco packet tracer. It's the basic topology; you can use it to complete Part B.

The goal is to practice using the basic commands of OSPF and standard ACLs. Please do the following configurations:
- Configure the IP addresses as:
- Host A: 10.1.1.1/24. Gateway: 10.1.1.3
- Host B: 10.1.1.2/24. Gateway: 10.1.1.3
- R1´s G0/0: 10.1.1.3/24
- Host C: 10.3.3.3/25. Gateway: 10.3.3.1
- R1´s G0/1: 10.3.3.1/25
- S1: 10.2.2.1/24. Gateway: 10.2.2.3
- S2: 10.2.2.2/24. Gateway: 10.2.2.3
- R2´s G0/0: 10.2.2.3/24
- R1´s S0/3/0: 10.4.4.1/30
- R2´s S0/3/0: 10.4.4.2/30

Check that you can ping between hosts in the same subnet:

From Host A to Host B.
From Host C to R1´s G0/1 interface.
From S1 to S2.
From R1´s S0/3/0 interface to R2´s S0/3/0 interface.

Note that you can´t ping between hosts in different subnets because the routers don´t have any entry in their routing table.

- Enable OSPF in all interfaces, both R1 and R2 (area 0), with only one subcommand in the OSPF configuration.
Check that the neighboring relationships have been created between R1 and R2. Check that, after configuring OSPF, you can ping between hosts in different subnets.
From Host A to Host C.
From Host C to S1.
From Host A to S1.

- Configure ACL on the right routers, interfaces and directions based on these requirements:
Permit packets from S1 going to subnet of hosts A and B.
Deny packets from S2 going to subnet of host A and B.
Permit packets from S2 going to subnet of host C.
Deny packets from S1 going to subnet of host C. After configuring ACL, check that:
You can ping from S1 to host A and B, but not to host C.
You can ping from S2 to host C, but not to hosts A and B.

Assessment 2:

Introduction
This is a Group assessment comprised of 3~5 Students. All group members must have to present their part in the demonstration/presentation.

Part A (Detailed Design): In this group assignment, you will assess the given case study to design a multi-level subnetting and provide a subnetted IP design plan. You must create a network topology using a network simulator (Cisco Packet Tracer) with the necessary labels and write a report on the design rationale. Each group must submit a report with the IP design plan, network topology screenshot and network design rationales.

Part B (Detailed Topology, Configuration and Demonstration): Using the network simulator (Cisco Packet Tracer), your group should configure the network designed for Part A. Each group must submit a report containing configuration commands and their descriptions and present the network demonstration.

Task
The report must follow the marking guide. Please note that citation of sources is mandatory and must be in the IEEE style.

Report Layout
The report layout, language and structure should be appropriate. The report should include title, table of contents, table of figures, sections and subsections heading and numbering, figures and tables numbers, citing tables, figures and references in the body text.

The reference section will add the references in IEEE format.
