You can't access pages via TMG as proxy with https inspection enabled on port different than 443

So, if you try to access pages via https on port different than 443 via TMG with https inspection enabled and you check logs on TMG you can see the following error "12204 The specified Secure Sockets Layer (SSL) port is not allowed. Forefront TMG is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests".
As a solution to this error I have bumped on the following article . There are three scripts for managing tunnel port ranges (view,add,delete). In my case I should access 8443 for ssl. So, I have added new tunnel port range with single port 8443. Started the script like : "cscript addrange.vbs ssl8443 8443" . And, TMG started proxyng ssl requests to requested destination on 8443.
