Revisited an old experiment of mine (https://github.com/dan-v/awslambdaproxy): can AWS Lambda functions work as network proxies? This time using UDP NAT hole punching + QUIC tunnels.
Client discovers public IP via STUN, writes session data to S3, which triggers a Lambda. Both endpoints punch UDP holes through their NATs, then establish a QUIC connection for encrypted traffic forwarding.
