Attempting to following https://aws.amazon.com/premiumsupport/knowledge-center/nat-gateway-vpc-private-subnet/ , I have the following components:
- NAT Gateway
subnet-aaaconfigured to host
- Route Table
rtb-bbbconfigured with route:
subnet-bbbconfigured to use route table
- EC2 instance
id-ccc has a public IP, however whilst applied to
subnet-bbb I am unable to make any connections directly do it via the public IP. Is an additional route needed on
rtb-bbb to allow this? I was understanding that route tables are more of an outbound configuration and not responsible for inbound connections?
All subnets are using the same Network ACL, which is the VPC default of allow all inbound.
