True or False: Virtual Private Cloud (VPC) NAT gateways support port forwarding.

True or False: Virtual Private Cloud (VPC) NAT gateways support port forwarding.

• A. True
• B. False
• C. Only with specific configurations
• D. Not applicable

Answer: (B)

The statement that VPC NAT gateways support port forwarding is false. NAT (Network Address Translation) gateways in AWS are designed primarily for enabling outbound internet access for resources within a private subnet. They allow instances in a private subnet to initiate outbound traffic to the internet while preventing unsolicited inbound traffic from reaching those instances. The functionality of a NAT gateway revolves around translating private IP addresses to a public address for outbound requests and doing the reverse for responses. However, traditional port forwarding, which forwards TCP or UDP packets from a specified port on one IP address to a specified port on another IP address, is not a feature of NAT gateways. Instead, for port forwarding functionality, you would typically use a different service, such as an Elastic Load Balancer or an EC2 instance configured specifically to handle port forwarding requests. Understanding these distinctions is important for designing effective and secure architectures in AWS, particularly when managing network traffic and access to resources.
