Step 4: Create and Assign Route Tables

Route tables control how network traffic flows within your VPC. You will create two route tables: one for the public subnet and one for the private subnet.

Naming Convention

Use descriptive names that include subnet information to help with identification:

  • PUBLIC ROUTE 10.0.1.x - For the public subnet
  • PRIVATE ROUTE 10.0.2.x - For the private subnet

Create the Route Tables

  1. Navigate to VPC Dashboard and select Route Tables.
  1. Click Create Route Table.
  1. Enter PUBLIC ROUTE 10.0.1.x as the name tag.
  1. Select My-Company-VPC and click Create.
  1. Repeat steps 2-4 to create PRIVATE ROUTE 10.0.2.x.

Configure the Public Route Table

  1. Select PUBLIC ROUTE 10.0.1.x from the list.
  1. Click the Routes tab.
  1. Click Edit and then Add Another Route.
  1. Enter the following:
Destination Target
0.0.0.0/0 My-Company-IGW
  1. Click Save.
  1. Click the Subnet Associations tab.
  1. Click Edit and check the box next to Public-Subnet (10.0.1.0/24).
  1. Click Save.

This configuration enables communication between your public subnet and the internet.

Configure the Private Route Table

  1. Select PRIVATE ROUTE 10.0.2.x from the list.
  1. Click the Subnet Associations tab.
  1. Click Edit and check the box next to Private-Subnet (10.0.2.0/24).
  1. Click Save.

Note: The private route table does not need an internet gateway route. Private subnet instances access the internet through a NAT gateway (optional, not covered in this guide).
