Client Ip in Webserver

Dear Team,

 

 

I have couple of webservers hosted behind my LB, I need to record the client ip of those who all visit my website, now I am getting the IP of LB but I need to know the real client ip.

    Hi Manu,

     

     

    For HTTP (or HTTPS traffic that is decypted on LTM), you can have LTM insert the original client IP address in the X-Forwarded-For header by creating a custom HTTP profile with 'Insert XFF' enabled. You can then configure the web server to parse this custom HTTP header value and log it. See this post for details:
