    Sometimes you'll have traffic come from another source such as Cloudflare, another proxy source, or a dedicated firewall. Apache offers mod_remoteip which will allow you to restore the original visitor address.

    Apache's mod_remoteip allows Apache to extract the visitor IP from requests received from proxies and load balancers. This enables your website and logs to know the actual visitor IP, rather than the connection showing the proxy or load balancer's IP. This guide will cover how to install and configure mod_remoteip.

    --------------------------------------------------




    :
    yum install ea-apache24-mod_remoteip
    --------------------------------------------------
    2- RemoteIPHeader
    --------------------------------------------------




    RemoteIPHeader should be replaced with the header used to pass the visitor IP from the proxy or load balancer. Typically,
    this will be one of the following. Note that Nginx with Reverse Proxy (ea-nginx) uses the X-Forwarded-For header.


    • X-Forwarded-For
    • X-Client-IP
    • X-Cluster-Client-IP
    • CF-Connecting-IP

    And modify both of the LogFormat (combined, and common) by replace the "h" with an
    "a".


    :
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
    LogFormat "%h %l %u %t \"%r\" %>s %b" common

    :
    LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
    LogFormat "%a %l %u %t \"%r\" %>s %b" common
    This format captures the header with the %h field which is the proxy address in our example.
    Because we want the originating client IP address instead of the remote IP being logged, we replace this with an %a.

    Save and restart Apache and that should handle this.


    --------------------------------------------------

    Test the configuration.


    Run the following command to check the Apache configuration. Any errors will need to be resolved before proceeding.

    :
    apachectl -t
    Restart Apache with the following command.

    : CloudFlare Restoring visitors IP with mod_remoteip

    mod_remoteip was enabled, why do I still see CloudFlare IPs when I execute "netstat"?


    The "netstat" command will review network data that your server receives. From a network standpoint, CloudFlare is connecting to your server. The data that CloudFlare sends to the webserver in headers would contain the IP that you are looking for. Apache's mod_remoteip will extract the IP from those headers and place them in your logs. As a result, you will see the real IP in logs, but not within "netstat" output.
