5/27/2023 0 Comments Aws waf nlb![]() ![]() but NLB requires static addresses for its targets. The problem is that Application Load Balancers can scale up, out, in, and/or down, and in each case the internal IP addresses of the balancers can change. ALBs targeted in this fashion will provide the X-Forwarded-For header containing the external IP address originally invoking the NLB. This not only reduces the complexity of needing a Lambda-based workaround but also removes the limitation concerning client IP preservation. ![]() September 2021 Update: AWS has announced the native availability of ALB Target Groups for NLBs.
