What is X-Forwarded-For function and how can I use it?

The X-Forwarded-For (XFF) HTTP header field is a standard for identifying the originating IP address of a client connecting to a web server through an HTTP proxy. In other words, the original source IP will be shown in your server from any connection through Nexusguard Proxy.

This function is available to all users by default. Please contact your system developer for the details of setting on your server side.
