Question

Load Balancer forward client public IP address

How can I access the public IP address of the client behind a DO load balancer?

Does the load balancer send any header with this IMPORTANT info? Can’t find it in my $_SERVER info array :(

thanks!

If you use var_dump( $_SERVER ); are you not seeing X-Forwarded-For?

You’ll want to look for HTTP_X_ headers when it comes to fetching information coming from the LB, such as the proto (HTTP/HTTPS), port, and client IP.

HTTP_X_FORWARDED_PORT

HTTP_X_FORWARDED_PROTO

HTTP_X_FORWARDED_FOR

I never figured it out. For a few minutes I thought the nginx fix posted in stackoverflow was the solution, but then I saw it was not working either, so I removed the DigitalOcean load balancers and setup one on my own with a cheaper $10 droplet.
