Sorry.  You are correct.  This is the first time we have used HTTP/HTTPS
publishing.  The logon HTTPS interface is separate from the ICA client
traffic and therefore would not traverse the SSL session as you
mentioned.  I see that Citrix has just announced version 4 with a
gateway appliance as a replacement to the gateway software.

How do you plan to encapsulate the ICA traffic in SSL? The protocol is
ICA, it has a specific port and the client isn't smart enough on its own
to do the encapsulation. You can SSL the web interface but you can not
do anything more than the RC5 encryption available natively in
metaframe. 
Many people use this method although it is not a "best practice".

The clients are set for basic encryption anyway.  If we take the citrix
client bacsic encryption and wrap it in SSL, we can pretty pretty much
call it "safe" at that point, yes?  Am I missing anything?  I have
already built the web publishing rule and created the new web listener.
It seems to work okay.

You can publish the web interface via HTTP or SSL. 
You can specify an alternative IP address for the Citrix server to the
outside if ISA and then publish it via ISA You can not secure the ICA
protocol with encryption via ISA

The Citrix SSL gateway interacts with the client to define the protocol
that the client should attempt to connect to the server with. ISA can
not do this for you.

Has anybody attempted to publish Citrix Metaframe through ISA?  Citrix
provides their own gateway server product to proxy the citrix
connections to the internal server and provide SSL.  But I was wondering
if anyone had removed the middle man in this case and published
Metaframe something like an exchange server.  Put the SSL certificate on
the Metaframe server and then export it to the ISA box.  Is this
"do-able"?
