No no no no no. The ONLY thing that should potentially be in the DMZ is an Edge server. And if you have something else already doing antispam/antivirus you won't need an edge server.
Question #1 & #2: how many users and how large a mailstore do you need to support? Regards, Michael B. Smith Consultant and Exchange MVP http://TheEssentialExchange.com From: Jimmy Tran [mailto:jt...@teachtci.com] Sent: Wednesday, November 23, 2011 11:49 AM To: MS-Exchange Admin Issues Subject: placement of 2010 servers I am working on designing our email migration from exchange 2003 to exchange 2010. I was planning on starting with a simple setup, 1 cas/hub server and 1 mbx server. I am still unsure of the placement of the cas/hub server because from what I understand, the CAS should be in the perimeter/dmz. Does the HUB need to be outside too? How do you guys have your servers placed in regards to the perimeter and private network? Any pointers would be awesome.
