Question. 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?
