SSL and IWP?

[Ewarrior]

Does anyone have some tips on getting IWP to work with SSL?

I'm running a two box setup with Filemaker Server 8 Advanced running on a Mac OS X 10.4.9 box. I have another box running Mac OS X Server 10.4.9 hosting the website with the Filemaker WPE. The setup works beautifully. However when I turn SSL on in the Mac OS X Server box and the default port changes from port 80 to 443 the WPE cannot connect to the database. I've checked the firewall setting on the Mac OS X Server box to allow traffic on port 443. I can get to the console page:

"https://www.mydomain.com:443/fmi/config"

but it indicates that the WPE can't communicate with the database. Do I need to also turn on SSL in the Filemaker Server 8 Advanced box? It doesn't seem to be needed since I only need SSL on IWP connections not LAN connections. Is there somewhere in FMS8A that I can tell it to connect to the WPE box using port 443? Any suggestions?
