Why can’t I create a NACL and route table before a VPC on AWS? | by Teri Radichel | Biting Bugs | December 2023


Then I could associate the route table and NACL with the VPC when I create it

I have to jump through all these hoops to fix a NACL and VPC route table after creating it. It would be really great if I could create the routing table and NACL first, independently. The same concept that is used for an Elastic IP address.

Then, when I create my VPC, I want to be able to specify the route table and NACL to use at deployment time.

But I guess maybe there is something about having to associate a subnet with a NACL that is associated with the same VPC? I’m not sure, but I’m sure there is a way to make it work. This might involve creating a route table which is essentially a template used to generate a route table attached to a VPC, for example.

Anyway, just a thought, as the complexity of fixing routing tables and NACLs not present in CloudFormation after the fact seems more complicated than it should be.
