Ah, I was wondering about that. Glad I now know the SLB hides the real client IP. That's a neat feature.

Haha, so the backend ECS instances will have no idea who's really accessing them. Gotta love that SLB obfuscation!

I thought the SLB just forwarded the requests without modifying the headers. Good to know it replaces the IP address.

That's correct! The SLB will replace the client's IP address with its own when forwarding layer 7 requests.
