Configuring a NAT Network . NAME: ___________________________________ STUDENT#: ______________________ Introduction Packet Tracer is integrated throughout this course. You must know how to navigate the Packet Tracer environment to complete this course. Make sure that you have watched the video on how to use Packet Tracer. Use the tutorials if you require a review of Packet Tracer fundamentals. The tutorials are located in the Packet Tracer Help menu. This lab focuses on configuring both Dynamic NAT and Static NAT. Save the Packet Tracer lab file and the written assignment using the following naming convention: Last Name-Student number. Both the Packet Tracer lab assignment and your written lab assignment must be submitted by 11:30 pm of the fifth day after you are assigned the lab (i.e. if your class is on Tuesday, you must submit both parts of your lab assignment on Sunday). These will be submitted via the Dropbox on eLearn. Any lab not submitted by that time will receive a mark of 0% for the lab regardless of the reason. I, (name/student#) ________________________________________, hereby state that this lab is solely my work and no other student helped or did my work for me, nor was it copied from another lab. Failure to put your name in this statement of authorship for the written portion of the lab will result in a 5% loss of marks for this lab. Copy and Paste Instructions You are to copy the exact commands and any output from PT to the PDF form. Do not edit it in any way. The command must show the device name where you inputted the command. The same is to be done with any output. The PDF form is set up to handle long inputs and a scroll bar will appear on the right to show you that there is more information than can be seen. FAILURE to do this will result in a mark of zero for that question Page 1 of 11 Packet Tracer When you open Packet Tracer you will see the following dialog box: Replace Guest with your First name and student number in the space marked Name as well as your email address in the space marked E-Mail. In the Addition Info box copy the following bolded sentence and paste it into the blank area. When pasting into Packet Tracer use the mouse and right click to insert the text. Copy and paste the following: I, name/student #, hereby state that this lab is solely my work and no other student helped or did my work for me. Remember: having someone else do any of your work and then submit it as your own is deemed to be one of the items that falls under the heading of Academic Dishonesty. When it is filled in, the User Profile should look like the example shown below. Click OK and then go to File > Save As and save your file as per the instructions on the first page. You are now ready to start your lab.

Part 2: Configure OSPF for a single area on the NATRouter and the NATtoServer router Part 3: Configure Dynamic NAT for PC1, PC2, L1 and L2 on the NATRouter Part 4: Configure Static NAT to the NATServer on the NATtoServer router Part 5: Verify Connectivity Scenario You are tasked with configuring NAT for the Widgets Company. You must not advertise some of the networks to any devices outside of the NAT’d portions of your network. You must also configure OSPF for the network. (The devices in the Internet cloud have already been configured and you do not need to do anything to them) Part 1: Configure OSPF on the NATRouter and the NATtoServer router Step 1: Configure OSPF for a single area using Cisco’s Best Practice for your network statements on the NATRouter. Do not advertise the 10.4.11.32 or the 10.4.10.32 networks. Use 1 as your process ID. Copy and paste the commands you used and any output from the commands you used in PT here. Do not type your answer or modify the output you copied. Step 2: Configure OSPF for a single area using Cisco’s Best Practice for your network statements on the NATtoServer router. Do not advertise the 15.15.15.96 network. Use 1 as your process ID. Copy and paste the commands you used and any output from the commands you used in PT here. Do not type your answer or modify the output you copied. Page 4 of 11 Step 3: Verify that OSPF is working on and between the NATRouter and NATtoServer router. What is the command that you used to accomplish this task? Type this command here. Copy and paste the commands you used and any output from the commands you used in PT here. Do not type your answer or modify the output you copied. Copy and paste the commands you used and any output from the commands you used in PT here.
