Overview

In order to achieve the goal of this lab, you will have to go through the following steps:

Step 1 - Run Lab-002

Repeat all of the steps described in lab-002, making sure that any reference to lab-002 are replaced by lab-003.

Step 2 - Create a NAT Gateway

Create a NAT gateway in the public subnet. Note that an elastic public IP must be allocated before a NAT gateway can be created.

  

Step 3 - Create a Route Table

Create a new route table with the Name tag private and with a default route to the NAT gateway created in step 2.

      

Step 4 - Associate the Route Table to the Private Subnet

Associate the newly created route table to the private subnet.
