Update Private Route Tables

We have two route tables, one for each private subnet. For now, these route tables just have a local route.

We need to add them another route that points to the ENI that will be attached to the NAT instance.

1. Open the VPC console (opens in a new tab).

2. In the sidebar, choose Route Tables.

3. Select the route table associated with the first private subnet.

4. Choose the Routes tab and then Edit routes.

5. Choose Add route.

6. In the Destination field, enter 0.0.0.0/0.

7. In the Target field, choose Network Interface and select the Network Interface ID we created in the previous step.

8. Choose Save changes.

   

Repeat the same steps for the route table associated with the second private subnet.
