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.
