Hi all, for last few days I am facing problem while configuring ELB at Amazon cloud (EC2). The issue is, I am not getting client IP address while I have configured the ELB listener in Layer 4(TCP) mode in server variable, while I am getting that in Layer 7(HTTP) mode. I need client IP for my application.
Still ELB has the issue of SSL/TLS Renegotiation vulnerability. So, I am not able to use ELB listener in Layer7(HTTP) mode, rather I am using ELB listener in Layer4(TCP) mode and handle the SSL/TLS Renegotiation vulnerability through Apache web server. That means...... Mode of Listener | Client IP address | SSL/TLS Renegotiation vulnerability --------------------------------------------------------------------------------------------------------------------------------------- Layer4(TCP) | Not Available | Vulnerability can be overcome Layer7(HTTP) | Available | Vulnerability can not be overcome I need both the feature(Client IP and Vulnerability overcome). I have written to Amazon support, but till now got very poor support from them. Now I am posting this issue to these list, so that if anyone have any idea to resolve that can share with everyone. Below is the mail that I have written to Amazon support...... --------------------------------------------------- Hi, as per the document published at http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-listener-config.html .... "When you use TCP for both front-end and back-end connections, your load balancer will forward the request to the back-end instances without modification to the headers." But unfortunately I am not getting IP address of client from the server variable "REMOTE_ADDR" on Layer 4 configuration of ELB. I am getting modified address on that variable. How can I get the actual one? I have no option to create Layer 7 configuration of ELB because still ELB has issue with SSL/TLS Renegotiation. Currently I am handling this issue from Apache server of back-end instance. Now I need to know the process to know the IP address of client through Layer 4 configuration of ELB. Without client IP our application will not run properly. I am not able to run the application. Waiting for prompt reply .. thanks. --------------------------------------------------- --- Nirmalya Lahiri Mobile: +91-9433113536 VOIP: nirmalyalah...@sip.linphone.org _______________________________________ Pune GNU/Linux Users Group Mailing List
