Steve Why do you use a different farm? Do you see it offers significant security features by doing this. If so ,What exactly? If it's a small farm it's quite costly to build the redundancy.

The TermServer app talks thru the firewall to an internal SQL server database. We just create user ID's in the external DMZ domain for them to use. What else would you suggest? ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Greenberg Sent: Wednesday, April 25, 2007 11:58 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Citrix on DMZ We have done it a number of times for secure government business to business applications. This is where the app and data is on the Presentation Server and the security policy disallows internal access. In these cases the server is usually a standalone farm and if I knew what was running on it they would have to kill me J Steve Greenberg Thin Client Computing 34522 N.

Why would want to put a Presentation server in the DMZ? I know there are some valid reasons, so make sure to take the litmus test first. It's 2512, 80 (or whatever the XML port is), 1494, 2598, 27000, the TS Licensing Port. Joe From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Turman, David C. Sent: Tuesday, April 24, 2007 12:51 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Citrix on DMZ If I were to put a Presentation Server 4.0 box on a DMZ, what ports would I need to open on the firewall to have it talk to and be a member of a Presentation Server 4.0 Citrix Farm on the insdie of the firewall? I'm assuming at least 1433. Any others or problems with doing this?
