You can achieve this with TPROXY, I believe. It requires kernel support, and has routing and complexity implications for your infrastructure. Here's a post referenced from the main HAProxy website, describing this: http://blog.loadbalancer.org/configure-haproxy-with-tproxy-kernel-for-full-transparent-proxy/ You might alternatively request that your application/server vendor implements "PROXY" protocol support, which passes the client IP information in-band: http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt If you have the option of using HTTP, I suggest you will find that using the X-Forwarded-For "standard" is a /far/ simpler solution than either of these.
