C# - Getting The IP Address Of User?

I am trying to fetch the IP address using this:-

protected void Page_Load(object sender, EventArgs e)
{
string ClientIP;
ClientIP = HttpContext.Current.Request.UserHostAddress;
Label1.Text = ClientIP;
}

This code outputs 127.0.0.1.

And the code below displays nothing!

string ClientIP;
ClientIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
Label1.Text = ClientIP;

How do I fetch the IP address? The REAL IP address of a user?

[EDIT]

I don't want EXACT location BTW. I need to know the country and then redirect the user to a webpage accordingly.
