Egress Only Internet Gateway

An Egress Only Internet Gateway is a type of internet gateway specifically designed for providing a route to the internet that prevents unsolicited inbound traffic to your instances located within an Amazon Virtual Private Cloud (VPC). It allows IPv6-enabled resources within the VPC to access the internet while blocking incoming traffic that was not initiated by those resources. More information can be found in the official AWS documentation.

An Egress Only Internet Gateway is directly related to an EC2 Virtual Private Cloud (VPC) as it is used within the VPC to control and manage outbound internet traffic for IPv6-enabled instances. It allows these instances to communicate with the internet securely while preventing any unsolicited inbound connections. The setup and functionality of an Egress Only Internet Gateway are crucial for maintaining a secure VPC environment.
