We need an AWS account and user with proper permissions for creating a NAT instance on EC2. Create an EC2 in the same way as the previous recipe. The only difference is, you don't put any Advanced Details in the Choose Network page. In the security group page, create NATSG security group and attach the same with instance with the following rules. We are allowing all traffic for simplicity. However, you should only put the required CIDR ranges.
