Question : ISA - HTTP 502 Proxy Error

I have recenlty installed ISA Server with SP1 and FP1 on a windows 2003 server, this installation is just for webcache only(simply webproxy) without any firewall etc.((I have plan to setup FW separately)), anyways, when i point my web browser to any site lDirectly', it works, but when I try to access through proxy server it gives me this error:

======
HTTP 502 Proxy Error - The ISA Server denies the specified Uniform
Resource Locator (URL). (12202)
Internet Security and Acceleration Server

Although, this is a fresh installation, I havnt sent any of the Access Policy eliments etc. I dont know what is stopping it to access.

Thanks..

You have to define Client Sets and related attributes.

You must define 3 sets of attributes for each client set you want to give access to. The client addresses, the Access policy and the permissible timing.
