Hey guys,

Need some advice with the following senario.
We have 3 exchange 2007 boxes which are all on the internal network.
1. Mailbox
2. Edge server
3. Hub/client

There is no current SPAM appliance in place so i will be purchasing one configuring it on a ISA DMZ. ALong with this i would like to move the EDGE exchange box to the DMZ along side the SPAM. Traffic flow would be internet --> SPAM --> EDGE --> internal...

1. Is this the right way to go about things?
2. Do i really need the EDGE server is i have SPAM appliance?

Any advice of tip around this would be great.
Thanks in advanced.

If you are buying an appliance then you would probably want to get rid of the Edge box. If there isn't "any" (famous last words) spam coming in you have to think what the Edge gets you. All you have is address whitelisting and a few other toys. Do you need that added level of complexity for a small feature-set? I wouldn't.

Internet > Appliance > HT is perfectly fine.

Besides changes the edge connector to point to the APP do i need to reinstall and exchange services on the backend once the edge server is removed?
From what i know the new TMG firewall actually has edge services supported? Is this something i should consider or is it not really needed because of my plans to use a APP.

You need to remove the subscription for the Edge from the HT. That's all you need to do unless you have done something hinky with routing outbound messages.

I would also think very carefully about bothering with ISA/TMG since it's dead as a standalone product. Maybe take the time now to implement a proper firewall device.
