We are using Exchange Direct Push.

We use two ISA 2004 Firewall servers (Network Load Balanced) in our DMZ, (in a 
workgroup config), backed off to, two front-end servers Network Load Balanced, 
we have three clustered EVS behind the front-ends.

Front-end and Back-end servers are in our internal LAN.

ISA 2004 servers in the DMZ. (workgroup)

TCP 443, opened into the LAN.

Same certificiate used on all front-end and isa servers.

ISA 2004 OWA Published Rule setup on ISA.

We use XDA II/IIS/Mini IIs and ActiveSync

  Is anyone using the new exchange direct push technology yet?

  I was told that to enable it I would need to map 443 from the Internet to my 
Exchange server, and also that I would need an SSL certificate installed. 

  I'm wondering if anyone has done it with only 1 exchange server? I have 1 
exchange server behind 1 firewall. No seperate exchange front end, no seperate 
smpt server, and we dont use owa, so no owa server. Just 1 exchange box. 

  I always have concerns opening ports up, so curious what other people are 
doing. Would you only do this if you had a front end exchange box in a DMZ?

  Thanks in advance,
