I have a LAN-based web server with HTTPS running on port 37888. I created an "HTTPS High" protocol definition, and Server-published from the ISA external adapter to internal web server IP number. I opened IE on the ISA box and went to "https://192.168.100.12:37888"; and IE says "The Page cannot be displayed". If I use IE to go to "https://internalserver:37888"; then the page opens properly. If I use IE from an internet host to go to "https://dns.address.com:37888"; I also get "The Page cannot be displayed". There are no Event Log or W3Svc errors. This prevents me from using ISA to server-publish the site because for some reason ISA won't touch the internal server when an IP number is used. What did I miss? I need to publish this SSL site on a high port number. Thanks. NOTICE: This communication, including attachments, is information that is confidential and may be privileged.
