We are pleased to announce that, starting today, you can preserve client IP addresses towards Network Load Balancers (NLBs) with AWS Global Accelerator. With this feature, you can meet security and compliance restrictions around client IP addresses, apply client-specific logic for IP address or location-based filters, or gather connection statistics. You can also use client IP address preservation to serve personalized content in your applications.

You can enable client IP address preservation when you configure NLB endpoints behind your accelerator on a per-endpoint basis. Note that client IP address preservation is only supported for NLBs with security groups enabled. For existing accelerators, client IP address preservation is disabled for NLBs by default. You can continue to monitor your traffic with existing Global Accelerator CloudWatch metrics. Client IP address preservation for NLB endpoints is available in all AWS Regions where Global Accelerator is supported. The full list of supported Regions is available here.

There are no additional costs for client IP address preservation with NLB endpoints. To learn more about client IP address preservation, see the Global Accelerator product page and the documentation.
