When you are using a client computer that is behind Proxy Server 2.0 and you try to access an external Internet Web site using the Web Proxy service, you may receive the following error message:
HTTP Error 403
403.6 Forbidden: IP address rejected
This error is caused when the server has a list of IP addresses that are not allowed to access the site, and the IP address you are using is in this list.
Please contact the Web server's administrator if the problem persists
