cURL don't hide user IP addresses

hey guys,

Is there any way to not have cURL act like a proxy server in that it DOES let external web servers that it makes HTTP requests to see the original IP address of users who surf get info via cURL on a cURL-using proxy web server.

I imagine a lot of sites try and block proxy servers because of bypassing, but is there any way to be friendly and keep from breaking policies like bypassing firewalls and content filterers?

No. Your server makes the request not the user, you can forge the IP but then you will not get it back.
