Folks, I have done a setup where I am using Stunnel to forward incoming HTTPS requests to HaProxy. But, I am unable to get IP address at HaProxy level (determined by looking at logs) - Here is the configuration file for Stunnel - cert = /etc/stunnel/ssl.crt key = /etc/apache2/ssl.key/socialappshq.com.key sslVersion = all chroot = /var/lib/stunnel4/ setuid = stunnel4 setgid = stunnel4 pid = /stunnel.pid ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 CAfile = /etc/apache2/ssl.key/ca.pem output = /var/log/stunnel4/stunnel.log [proxy] accept = 443 connect = 81 TIMEOUTclose = 0 Here is the config file for HaProxy - global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 4096 user haproxy group haproxy defaults log global option httplog option dontlognull mode http stats enable retries 3 option redispatch maxconn 2000 timeout client 40s # Client and server timeout must match the longest timeout server 40s # time we may wait for a response from the server. timeout queue 40s # Don't queue requests too long if saturated. timeout connect 20s # There's no reason to change this one. timeout http-request 30s # A complete request may never take that long. frontend webfarm_ssl *:81 accept-proxy option httpclose option forwardfor acl is_social hdr_dom(host) -i socialappshq.com use_backend socialappshq_ssl if is_social backend socialappshq_ssl balance roundrobin cookie JSESSIONID prefix option httpchk GET /check.txt HTTP/1.0 server web2 ec2-XX.us-west-1.compute.amazonaws.com:8080 cookie B check inter 2000 rise 2 fall 3 What else should I do so that IP address passes from Stunnel to Haproxy? Your help will be extremely appreciated. Thx Rajat Garg https://www.socialappshq.com
