Transparent Proxy Issues w/ HAProxy Centos 7

Question

Having issues following steps to transparent proxy outlined here:

Howto transparent proxying and binding with HAProxy and ALOHA Load-Balancer | HAProxy Technologies – Aloha Load Balancer

Believe to successfully done all the steps but having issues layer 4 TLS requests. The goal being in TCP mode load balance http requests on port 80 and port 443 onto webserver, where webserver terminates TLS connections. BUT to have the webserver not see the haproxy box IP but to see the client IP. The link above is the what i continually see referenced everywhere on the internet for accomplishing this. Currently HAProxy will not route requests if have the line:

source 0.0.0.0 usesrc clientip 

included in the backend. Removing that line however, haproxy routes corretly but webserver sees the ip from haproxy box, not client.

Here is the relevant set up and configs:

bash> lsmod | grep -i tproxy
 xt_TPROXY              17327  0
 nf_defrag_ipv6         34651  2 xt_socket,xt_TPROXY
 nf_defrag_ipv4         12729  3 xt_socket,xt_TPROXY,nf_conntrack_ipv4

bash>sudo sysctl -p
 vm.swappiness = 0
 net.ipv4.ip_nonlocal_bind = 1
 net.ipv4.ip_forward = 1

bash> sudo iptables -L -n -t mangle
