502 error when accessing a web site using port 8443 in ISA server

Posted on 2007-07-23

We are running isa server 2000 and are attempting to access a site:
{sample format}
When we attempt to access it, we get a message stating we are not allowed to access it.
We get the following error:
HTTP 502 Proxy error - The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most web browsers use port 443 for SSL requests. (12204)
Does anyone have any idea why this would be happening or what we could do to fix it?
I read about a tool to extend the port range for SSL, but it doesn't seem to work on an isa 2000 server.
Does anyone have any idea how I can communicate with this site via port 8443?

    Accepted Solution

    Yes, you need to run this script to allow ISA to operate over ssl ports other than the standard 443.

    Run the isa_tpr script

    Have you tried this? If you need help with the syntax then let me know. Its best run from a cmd prompt rather than trying to do this from inside windows explorer as you need to pass parameters with it to cover the port range you want to add. If you run it from a windows cmd window then the syntax is shown for you.
