RaidenFTPD knowledge base no.00000046

A : When you are setting up a server behind a traditional NAT router that does not support UPnP NAT traversal , a server usually has no way to get the real WAN (external) IP address , but RaidenFTPD v2.4 build 740+ has the ability to query the WAN IP address from our online server '' http://www.raidenmaild.com/download/echo.php " , however you may want to setup your own Auto IP identification server for whatever reasons such as privacy issue , speed issue and etc..

1. Setup your own web server with php extension support , you can use IIS , APACHE , or RaidenHTTPD read

2. Download the Auto IP identification server script file from here

3. Extract this script to a directory under your web server

4. Edit your raidenftpd.ini , enter correct HOSTNAME and absolute URL for your script

for example , if your script is at http://www.raidenmaild.com/download/echo.php

make it as the following in the raidenftpd.ini file

AUTO_IP_IDENT_SERVERHOST=www.raidenmaild.com
AUTO_IP_IDENT_SERVERURL=/download/echo.php

if u're running IIS and don't wanna install php, u can do it with ASP.

VBScript:

<% @Language = "VBScript" %>

<%
Response.Write "YOUR_IP:" & Request.ServerVariables("REMOTE_ADDR") & "*"
%>

JScript:

<% @Language = "JScript" %>

<%
Response.Write('YOUR_IP:' + Request.ServerVariables("REMOTE_ADDR") + '*');
%>

and there was something missing in the php code ... so here's a working one i use:

PHP:

<?
echo "YOUR_IP:" . $_SERVER['REMOTE_ADDR'] . "*";
?>
