Lab - Troubleshooting NAT Configurations

b. Create a default route from the Gateway router to the ISP router.

Gateway(config)# ip route 0.0.0.0 0.0.0.0 s0/0/1

Step 6: Load router configurations.

The configurations for the routers are provided for you. There are errors with the configuration for the

Gateway router. Identify and correct the configurations errors.

Step 7: Save the running configuration to the startup configuration.

Part 2: Troubleshoot Static NAT

In Part 2, you will examine the static NAT for PC-A to determine if it is configured correctly. You will

troubleshoot the scenario until the correct static NAT is verified.

a. To troubleshoot issues with NAT, use the debug ip nat command. Turn on NAT debugging to see

translations in real-time across the Gateway router.

Gateway# debug ip nat

b. From PC-A, ping Lo0 on the ISP router. Do any NAT debug translations appear on the Gateway router?

____________________________________________________________________________________

No.

c. On the Gateway router, enter the command that allows you to see all current NAT translations on the

Gateway router. Write the command in the space below.

____________________________________________________________________________________

show ip nat translations

Gateway# show ip nat translations
