Sounds like there is a configuration error in the Citrix web interface. It is 
capable of detecting what network you are coming from and sending the 
appropriate ica file to you thus your client will be told to connect to the 
metaframe server directly. If I am accurate so far and this is your intention 
then all you should need to do is configure a direct access rule for the site 
and all protocols...(by IP or name etc)

In MF web interface you configure it to default to the alternate address and 
then configure exceptions for Normal address, enter the altaddr command on the 
metaframe server and reboot. 

Set up DNS to point the client to the web interface server on the inside and 
forget about the external people...nothing changes.

Steve,

I think Split DNS is great, but what we need is that when a client connects to 
applications.isaserver.net on port 80 it goes to a web server and when it 
connects to the same url applications.isaserver.net on port 1494 it goes to a 
different server, so how can you do that with DNS? Where do you configure DNS 
to detect what port you are accessing to?

The only way to do that (I think) is to have something (ISA) between client and 
both servers that detects the port and redirects the request to the correct 
server.

I know this configuration is not good, but I didn't make the design and now I 
have to solve the consequences.

No, not the way to do it. Have you heard of DNS, that's what that is for.

There are a couple of articles on www.isaserver.org dealing with split DNS, 
which is how you want to go forward from here.

Steve,

The fact is that we have this service published on Internet under an url as 
applications.isaserver.net and we have only a web interface that is not the 
same server as the presentation server, so when a client connects to the Web 
Interface from internet (port 80) ISA Server relay this to the web interface 
server and after when the client connects to the presentation server by 
applications.isaserver.net:1494 ISA redirects the request to the presentation 
server, so we use two rules to do that.

Well the problem is that our company wants to have the same url 
applications.isaserver.net for internal use, so we need to publish the service 
in our internal interface. Citrix admins have configure the .ica file to 
include the url applications.isaserver.net instead of an ip address.

Does anyone know how can we do that?

Thank you very much.

Why on earth would you be publishing your citric server internally.

Hi everybody,

I'm trying to publish a Citrix Server with ISA 2004. If I publish it defining 
Internal and External networks and configure rules to access from external 
network to an internal server all is ok, but if I publish the service on the 
internal interface and try to access from the same internal network, it doesn't 
work. In the log it seems like ISA get the connection as a Citrix client 
connection instead of a server inbound connection. I use a custom ICA protocol, 
but ISA gets the connection as the default ICA client protocol.

This problem doesn't happen with web server publishing.


Is there any way to force ISA 2004 to publish a port for internal use?
Is this a Bug?
Is a design limitation?

Thanks in advanced.
