Hey Angela, You would be best to configure at least the provided Secure Gateway option which comes with Presentation Server. Use this in conjunction with Web interface and you'll be able to securely deliver applications using a secure means. The PDF's supplied with the Web interface/Secure Gateway components on the CD tell you the rest. Alternatively you can use an Access Gateway, but this is an additional expense.

From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Angela Smith Sent: Tuesday, 12 February 2008 4:02 p.m. To: thin@xxxxxxxxxxxxx Subject: [THIN] Adding Web Interface Server to DMZ Hi We have 2 Web Interface 4.2 servers on our internal network using MS Network Load Balancing. I now have a requirement where I need to add a Web Interface Server in our DMZ for access for one of our external customers. They basically need to run 1 application on our Citrix Farm. All our Citrix components are on the internal network. We use SQL as our datastore. What is the best way to achieve this? What Ports need to be opened in the DMZ firewall for the Web Interface Server to talk to the Citrix Farm/SQL Data Store server which all reside on the internal network?
