Lab 6-2 PT - Configure Dynamic NAT

Objectives Part 1: Configure Dynamic NAT Part 2: Verify NAT Implementation

Note: You must configure the router hostnames to include your name (not your username). For example, I would rename the P2P-1 hostname “Sherif_P2P-1” as shown: Router(config)# hostname Sherif_P2P-1 Sherif_P2P-1(config)# Note on Screenshots You must include screenshots and short explanation as proof of completion when requested. The screenshots must: 

Be of your entire desktop and not “zoomed-in” to a specific area.



Include the router prompts with your name



Must include a short explanation of “What” and “Why” you are showing me this.

Note: Labs missing these will not be graded.

Background / Scenario 

This lab has is worth 1.5% of your total grade



Screen shot is worth 1 point

Explanation for each Screenshot is worth 1 point





Total points available in this lab is 8 points

1- Screenshot Sample:

2- Explanation Sample “what it should include”? 



What are you showing me? Specifically call out what you are supposed to look at in the output. If it’s the router ID then specify what it is. Also it is recommended if you can draw a circle or box around the item of interest. Why are you showing me this? (e.g., If you are verifying the Router ID as an example then the output proves that the router-id command was correctly assigned.)

PT - Configure Dynamic NAT

Instructions Part 1: Configure Dynamic NAT Step 1: Configure traffic that will be permitted. Open configuration window

On R2, configure one statement for ACL 1 to permit any address belonging to the 172.16.0.0/16 network. R2(config)# access-list 1 permit 172.16.0.0 0.0.255.255

Step 2: Configure a pool of address for NAT. Configure R2 with a NAT pool that uses two addresses in the 209.165.200.228/30 address space. R2(config)# ip nat pool ANY_POOL_NAME 209.165.200.229 209.165.200.230 netmask 255.255.255.252 Notice in the topology there are 3 network addresses that would be translated based on the ACL created. Question:

Notice that the Dynamic NAT is configured with a pool of only Two public addresses so if more than 2 devices attempt to access the internet, The additional devices would be denied access until one of the previous translations timed out freeing up an address to use.

Step 3: Associate ACL 1 with the NAT pool. Enter the command that associates ACL 1 with the NAT pool that you just created. R2(config)# ip nat inside source list 1 pool ANY_POOL_NAME

Step 4: Configure the NAT interfaces. Configure R2 interfaces with the appropriate inside and outside NAT commands. R2(config)# interface s0/0/0 R2(config-if)# ip nat outside R2(config-if)# interface s0/0/1 R2(config-if)# ip nat inside

Part 2: Verify NAT Implementation a. Provide a screen shot for the outcome of HTTP access from PC1 to Server 1 (209.165.201.5) (2 points)

1 point

Explanation: 1 point

As you can see http access is granted from PC1 to server1 (209.165.201.5) because we have Permit 172.16.0.0/16 to access Server1 using NAT.

c. Provide a screen shot for the outcome of “show ip nat translations” on R2 (2 points)

1 point

Explanation: 1 point

After entering the command “sh ip nat translations” we can see two address or ip addresses translated by using NAT.

d. Provide a screen shot for the outcome of “show ip nat statistics” on R2 (2 points)

1 point

Explanation: 1 point

If we can see in above screenshot after entering the command “s hip nat statistics” on R2 that command has two total translations (0 static, 2 dynamic, 2 extended). Also, Arrow in blue color indicates the Pool name and total addresses.
