AWS Transfer Family now supports source IP preservation for SFTP servers behind a Network Load Balancer (NLB)

Configure your AWS Transfer Family servers to enable source IP preservation using Proxy Protocol v2 (PPv2) for improved logging and authentication based on the client's true source IP.

Integrate source IP preservation into your SFTP server architecture to maintain accurate logs and enforce access controls based on the client's actual IP address.

Evaluate enabling source IP preservation on your SFTP servers to enhance IP-based auditing, access controls, and compliance, ensuring better visibility and security for your data transfers.
