我如何获取局域网中使用php从本地服务器访问网页的系统的IP地址

Question

I have a local network which connected to internet through a proxy server, The proxy server IP address is 192.168.0.1 . All systems in the network assigned IP address manually like 192.168.0-6.1-255 ,Subnet mask 255.255.248.0, Default gateway 192.168.0.1

and i created another server in local network for accessing my website locally and its IP address is 192.168.0.25 , Subnet Mask 255.255.255.0, Default gateway 192.168.0.25

All the systems in the local network can now access the website using the address

http://192.168.0.25/

I have to track all the systems accessing my website so i used the function $_SERVER['REMOTE_ADDR'] in php. But i getting the IP address of all system which accessing my website is as same as the proxy server IP address( 192.168.0.1 ).

Please help me to get the correct IP address of each system.

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))  
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) 
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }

echo $userIP = getRealIpAddr();
