This is typically port 8080.
In SSL Port, type the port number on which the upstream
server listens for Secure Sockets Layer (SSL) requests. This is
typically port 8443.
(Optional) If ISA Server should determine the configuration of
the upstream server, to retrieve objects from the upstream server,
click Automatically poll upstream server for the
configuration and type the Uniform Resource Locator (URL) for
the server.
(Optional) If the upstream server is accessible only when the
server supplies credentials, click Use this account, click
Set Account, and type the user name, password, and
authentication type.
(Optional) If ISA Server should dial out for primary

Important
When you select Automatically poll upstream server for the
configuration, ISA Server will determine the configuration of
the upstream server. The local ISA Server computer uses this
information to retrieve objects from the upstream server.
Because ISA Server supports pass-through authentication, the
authentication information of the client requesting the object is
passed to the upstream server. However, if the upstream server
might not be able to identify the client, you can specify Use
this account and supply which credentials to pass.
