Dear Team,

    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:
