I have an ISA Server 2006 in the DMZ with an SSL certificate that has an HTTPS listener. When ISA Server receives requests HTTPS request is sent via HTTPS HC internal web server. Thus, the ISA server handles Internet requests and HC web server is not open to the Internet at all. Very easy to configure.
