Can Request.UserHostAddress trace IP behind Proxy?

[Guest]

Hi

If I set a proxy in IE to view a view site.

My IP is 223.12.98.244 and the proxy IP is 202.156.87.179

Can Request.UserHostAddress trace 223.12.98.244? I use C#

If not, how can I trace the IP of the user?

I have a web application, I am afraid of being hacked and could not find the origin of the IP.

Any solution to solve this problem

Thanks

Tom,

Any respectable NAT/proxy isn't going to reveal this to you, as it is a
HUGE security gap. You aren't going to be able to trace back into this,
unless a proxy/NAT wants you to (and I can't think of any administrator that
would allow this). Also, chances are that it would mean nothing to you
anyways, since the IP that would be returned to you would be an internal
address which would have no meaning outside of the intranet that it was
based on.

What are you trying to do?

Since most hackers use others proxy servers (a chain) to perform hacking, I just to know whether there is a way to trace the real IP once my server is hacked.
