Description

Lab 7-2 PT - Configure Static NAT Objectives Part 1: Test Access without NAT Part 2: Configure Static NAT Part 3: Test Access with NAT

Note: You must configure the router hostnames to include your name (not your username). For example, I would rename the R1 hostname “Sherif_R1” as shown: Router(config)# hostname Sherif_R1 Sherif_R1(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. See screenshot Sample below

Scenario In IPv4 configured networks, clients and servers use private addressing. Before packets with private addressing can cross the internet, they need to be translated to public addressing. Servers that are accessed from outside the organization are usually assigned both a public and a private static IP address. In this activity, you will configure static NAT so that outside devices can access an inside server at its public address.

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.)

Instructions Part 1: Test Access without NAT Step 1: Attempt to connect to Server1 a. From PC1 or L1, use the Web Browser to attempt to connect to the Server1 web page at 172.16.16.1, try ping the server. The attempts should fail. C:\>ping 172.16.16.1 Pinging 172.16.16.1 with 32 bytes of data: Reply from 10.0.37.1: Destination host unreachable. Reply from 10.0.37.1: Destination host unreachable. Reply from 10.0.37.1: Destination host unreachable. Reply from 10.0.37.1: Destination host unreachable. Ping statistics for 172.16.16.1: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

b. From PC1, ping the R1 S0/0/0 interface (209.165.201.2). The ping should succeed. C:\>ping 209.165.201.2 Pinging 209.165.201.2 with 32 bytes of data: Reply from 209.165.201.2: bytes=32 time=1ms TTL=254 Reply from 209.165.201.2: bytes=32 time=4ms TTL=254 Reply from 209.165.201.2: bytes=32 time=7ms TTL=254 Reply from 209.165.201.2: bytes=32 time=1ms TTL=254 Ping statistics for 209.165.201.2: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 1ms, Maximum = 7ms, Average = 3ms

Step 1: View R1 routing table and running-config. c. View the running configuration of R1. Note that there are NO commands referring to NAT. An easy way to confirm this is to issue the following command: Open configuration window

R1# show run | include nat

d. Verify that the routing table does not contain entries referring to the IP network addresses for PC1 and L1. e. Verify that NAT is not being used by R1. R1# show ip nat translations

Close configuration window

Part 2: Configure Static NAT Step 1: Configure static NAT statements. Open configuration window

Refer to the Topology. Create a static NAT translation to map the Server1 inside address (Inside Local) to its outside public address (Inside Global) R1(config)# ip nat inside source static 172.16.16.1 64.100.50.1

Step 2: Configure interfaces. f.

Configure the G0/0 interface as an inside interface. R1(config)# interface g0/0 R1(config-if)# ip nat inside

g. Configure the s0/0/0 public interface as an outside interface. R1(config)# interface s0/0/0 R1(config-if)# ip nat outside

Step 3: Verify NAT configurations R1#sh ip nat statistics Total translations: 1 (1 static, 0 dynamic, 0 extended) Outside Interfaces: Serial0/0/0 Inside Interfaces: GigabitEthernet0/0 Hits: 0 Misses: 0 Expired translations: 0 Dynamic mappings: R1#sh ip nat translations Pro Inside global Inside local --- 64.100.50.1 172.16.16.1

Outside local Outside global -----

Part 3: Test Access with NAT Step 1: Verify connectivity to the Server1 web page. h. Provide a Screen shot for PC1 to show ping result to the public address for Server1 (64.100.50.1) (2 points) 1 point

Explanation: (1 point)

As per the above screenshot in Red Box we can see Ping from PC-1 to public server (64.100.50.1) succeed with 0%loss and using NAT for reaching public server.

i. Provide a Screen shot for L1 to show www (http) access to the public address for Server1 (64.100.50.1) (2 points)

1 point

Explanation: 1 point

Above Screenshot from L1 to show www (http) access to the public address for Server1 (64.100.50.1) succeed because we used NAT and which allow us to access server and keep your identity safe.

j. Provide a Screen shot for the output of “show ip nat translations” command on R1 (2 points) 1 point

Explanation: 1 point

After running the command “show ip nat translations” on R1, shows address translations done by NAT and its inside and outside local and global addresses. Also, It is showing static NAT
