Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)

I only have one rule and that is to let all traffic out to the external network at all times. I keep getting this error when I try to use the server as my proxy can anyone help.

Thanks,

Murray

Hi,

At first I had lots of issues with ISA Server, until I started paying attention to the logs. I don't remember about ISA2000, but on 2004, it tells you which rule is permiting/denying access, so you can fine tune your configuration.

What first comes to mind is that maybe you're trying to access the Internet from your ISA Server? If that's the case, ISA won't allow it, since there's a system policy that only lets you access very specific sites (windowsupdate.com, microsoft.com). Well this is for 2004 anyway.

First, what version are you using? And how is the rule you mention defined?
