We must create a route table to ensure that our subnets know how and where to route specific traffic. Execute the following steps to create a route table:
- Select Route Tables from the menu on the left and click the blue Create Route Table button:
- Configure the route table name as shown, select your VPC, and click Create:
- Select your new route table from the list of route tables shown. This will present you with the configuration options of the route table at the bottom of the screen (see the following screenshot).
- Select the Routes tab, and you will see that it only has one route – the default local route that all route tables have, enabling all subnets to talk to each other:
- Select Edit routes in order to add routes.
- Add the configuration as shown in the Destination field of the second route and select your own IGW as the target. This route sends all traffic without a known route to the IGW, which will then send it out to the internet...
