Accelerator for ActiveX Control?

I have been asked to set up an iChain accelerator for a Web-based
application that uses Windows Remote Desktop Web Connection. According
to Microsoft's documentation, this requires two ports: 3389 and
whatever IIS is configured to listen on (they recommend against using
port 80).


Has anyone else done this? Do I need to configure a second accelerator
as a tunnel on port 3389, or will it be sufficient to open port 3389 at
the firewall?

Thanks
