RPC over HTTP with IIS 6.0 and Exchange 2003

I would like to implement RPC over HTTP on a single Windows 2003 SBS server running Exchange 2003 and IIS 6.0. It is a DC and GC server with IIS 6.0, RPC Proxy installed, and a self-signed cert.  I've followed the instructions on msexchange.org and also used the RPCNoFrontEnd.exe tool to put the reg keys in, but the outlook clients still won't connect.  Are there any ports I have to open up on the outside firewall other than port 25?  I've tried to connect through HTTP proxy with both Outlook 2003 and Outlook 2007 with no luck.  Any ideas?  Thanks

Make sure you have port 443 open and are connecting through https.

Sorry, I forgot to add that.  I currently have Outlook Web Access running and it works fine through SSL.  Port 443 is already forwarded to the exchange server.
