Show HN: lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching Revisited an old experiment of mine ( https://ift.tt/Ko12OY8 ): 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. https://ift.tt/ijvneMl June 17, 2025 at 09:01AM
