OK,
Is FBA enabled on the listener you're using?

Authentication on the listener - only "Basic" is checked on. I think that is what you mean?

Is the client setup correctly?

I believe so:

Exchange server: Public FQDN
Username: johndoe

Proxy settings:
http://i86.photobucket.com/albums/k114/presidentbusch/exchproxy.jpg

Is the RPC proxy installed on the published server?

Yes, it appears because when I run a test from IE: https://email.example.org/rpc according this this KB http://support.microsoft.com/kb/884506/en-us all is well.

Thanks, for your help.
