Hi I have two Cisco 3750 redundant switches, a BlueCoat, an exchange server, a microwave connection, I want to connect them to a Cisco ASA 5510, and make a DMZ for the exchange server, Please some one give me an optimized diagram for the connection of those devices.

Thanks. We'll let you know when a new response is added.

I would suggest that you create a DMZ VLAN on the switches, connect a spare interface on the ASA to this VLAN as well as the Exchange server. The microwave obviously is your Internet, so this connects to the Outside interface of the ASA, and the defaukt VLAN on the switches is your inside. The BlueCoat can also sit on the inside, and the ASA confighured to only allow this to have Internet access using an inbound access-list.

Have a look at this document for details of how to configure the ASA (or PIX) to allow Exchange servers to work correctly when on a DMZ.
