Haha, good thing I read this. I was about to start troubleshooting why my ECS instances weren't showing the client IPs. SLB to the rescue!

Wait, really? I thought SLB would pass the client's IP. This could be a problem if I need to track the actual source IP. *scratches head*

Ah, so that's why my ECS instances always show the SLB IP in the logs. Glad I don't have to worry about the real client IP.

Hmm, I wasn't sure about that. Good to know that the backend sees the SLB IP instead of the client's IP.

True, that's correct. SLB does replace the source IP in the HTTP header when forwarding requests to the backend ECS instance.
