I log the ipaddress using ENV{REMOTE_ADDR} which works fine as long as
the person isn't using a proxy

My problem is when people are using proxy I am just getting the ipAddress of
the proxy

Is there a way to get the persons actual ipaddress when they are using a
proxy

No

if i go to http://all-nettools.com/toolbox and do the proxy test it
manages to show me the proxy ipaddress and also my actual computer
ipaddress. How does this site manage to do that?

Your proxy server is sending your IP address in a non-standard HTTP request
header field. Some proxy servers do this. Some do not

The purpose of the proxy test at all-nettools.com is to demonstrate that your
proxy server may not be protecting your privacy

Your purpose is to identify the actual IP address. Non-standard HTTP request
header fields are not appropriate for your purpose because they can be forged
easily
