Exchange ActiveSync, IPhone integration
Posted on 2011-02-10
I'm hoping to find some guidance with integrating IPhones into my org. Our current infrastruction consists of the following;
Exchange 2003 Server Std. Ed. . We have a SonicWall NSA 3500 Firewall, as well as a SonicWall SSL VPN 4000 appliance. Everything I have looked at, well almost everything, indicates that a front end Exchange server is a must for security. I understand that, & I also understand what needs to happen on my Firwall to allow ActiveSyn through. But, my concerns/questions are these...
How does my SSL VPN fall in this scenario? It uses port 443, since it is an SSL VPN device, & ActiveSync also calls for port 443 to be opend up on the Firewalll. As it sits, my plan is to get the Front End exchange server in place & make the neccassary changes to the firewall. But, I want to make sure that I am not missing anything in this with the SSL VPN appliance also being in play. Is there possibly some way to use that as a more secure "pass-thru" to forward the ActiveSync communication through to my Exchange Server? Or is there a more "ideal" or alternate way to set things up? Thanks for the input & guidance everyone.
