ISA 2006 had limitations on the web listener per protocol and physical network port.
I already have HTTPS web listener for email OWA access setup but need an additional https / ssl link from the dmz web server (hosts the main website) so a visitor to the site can login to a web applet and access the internal secure web server.
I have tried setting up the ports 20443 and directing the traffic from the dmz web site page to the internal server but the ISA blocks the traffic.
As the above web listener for the exchange server does not function correctly and is not absolutely necessary I could remove this and setup the Publish Web Site task and link to a fresh web listener for standard HTTPS port will this work. The documented procedure on Microsoft does not work, nor the ones I have found on other sites.
Has someone set this up before and can help overcome whatever is stopping this ISA working on this aspect?
