Using port redirection for the Altiris HelpDesk

Our network uses port based routing. I want to split off the Altiris HelpDesk traffic onto a different port eg; port 8086 instead of port 80, in order to route it over a different network path.

I have created a new web site in IIS, by cloning the existing Altiris default web site. This new website has been configured to use port 8086.

In the default web site I then modified the AexHD folder properties by selecting "a redirection to a URL" and entering http://altiris-server-name:8086

Finally, I found an Altiris  Knowledge base article: 23186, and edited the registry on the notification server  as follows:

1.   Open the registry key HKLM\Software\Altiris\eXpress\Helpdesk Package.

2. Create or edit the following strings with these values:
     AeXHDWebService = http://localhost:<Port#>/AeXHD/webservice.asmx 

     example http://localhost:8086/AeXHD/webservice.asmx

     Authority = "<ServerName>:<Port#>"
     example "Helpdesk:8086"

Can anyone tell me if they have perfromed a similar setup - or have any advise or recommendations as to whether this should work or not?
