Hello Toti,
Good day!
Thank you for posting here. Attaching an Internet Gateway to the VPC enables communication between instances in your VPC and the Internet, supporting both IPv4 and IPv6 traffic. When an Internet Gateway is attached to a VPC, it allows instances in public subnets to communicate with the Internet, facilitating both inbound and outbound traffic. However, the security policy requires that inbound IPv6 connections from the Internet be blocked. Simply attaching an Internet Gateway does not provide this level of control without additional configuration.
To fully meet these requirements, you would need to implement significant additional configurations. This makes using an Internet Gateway more complex compared to using an Egress-Only Internet Gateway and AWS Network Firewall, which can meet the requirements with less configuration.
I hope this clarifies things.
Thank you.
