I want to set up an Exchange 2007 server for testing and learning, and I want to protect it (preferably transparently) using my production SBS 2003 Premium Server (running ISA 2004 and Exchange 2003).

I do NOT want to join the new Exchange 2007 server (Windows Server 2003 Standard Ed) to my domain.

I DO want to have test users access it through the Internet (OWA, Outlook via HTTP, pushMail).

I would appreciate advice on setting up SBS / ISA 2004 to allow this.

Also:
I have an extra public IP I CAN use.
I have a separate Domain name I WANT to use.
Can this be done using ISA Web Listeners somehow?

Thanks!!

yes yes yes and yes.

it can be done. for how long it would work, i cannot say.

SBS is not comfotable with other DC's on its network.

Now there are several things you can do, install a new NIC to the server, make isa a three legged permieter, and sheild all traffic except smtp and OWA from that new network.

using the web listener you can point all traffic to a certain external IP to this new network.

in short you can do all you want, but i cant give you step by step guide as i would be here all day.

things to look for - does you isa connect directly to internet, or through adsl modem. can the adsl modem/ router support multiple public Ip's.

if it does, its easy :)

Hi Robert & Brian, some remarks here...

SBS has no problems with DC's in the network, you can have as many DC's in your network as you want, as long you have enough licenses ofcourse...

Adding a 3rd nic will break the SBS wizards on the production server, thus my advice don't do it..

Brian

If you have an extra public ip, a "hardware firewall" would be the best option here, on most firewalls you can assing your 2nd public ip to another port and is easy to allow/deny a rule.

You will need to join that server to the domain. If you want to start playing with it for learning purposes, start using a virtualisation solution.
