    It seems to be log from backend server!

     

    To preserve client IP address on server connection, you must disable source address translation in virtual server!

     

    But if you disable source address translation, you may have routing issues!

     

    This is why when we configure source address translation, we can add x-forwarded-for header to send to the server the client IP address
