We have two different 2003 Exchange servers.   What is the best way to utilize ISA 2004 so we can use OWA/OMA to access both servers?  Currently,we can only access one server via OWA/OMA.  The internet feed/smtp is from our office to theirs.  We connect via a T1.

With Exchange 2K we had setup a different website in IIS for each server(Equivalent to /exchange) and then setup two different web publishing rules.  Does not appear to work for 2003 (Also considering the OMA issue)


Thx JP

The best configuration is to setup a Front-end Exchange Server, and publish the FE Exchange Server. The FE Exchange Server can then route the requests to the appropriate BE servers.

Is that an option?

Not really at this point....   Bandwidth and server costs.

Is a second NIC in the ISA an option?

Thx JP

The ISA Firewall should always be multihomed! Who ever heard of a Firewall with a single NIC?

If you don't have a second NIC in that ISA Firewall yet, do it NOW! Single NIC (hork mode) config is NOT secure!

Is a second "EXTERNAL" nic an option?

- If not, Then

Sombody suggested I bind two external ip addresses to the one external nic and create a publishing rule for each.  That sounds much more feasible than installing a front-end server.  Is there any reason this would not work?

Thx JP

No, a second external NIC won't work. As a network security device, the ISA Firewall needs to logically and physcially partition the space between the source and destination.

HTH,
Tom

Tom,

What about binding another external IP to the one external NIC?  Then add another publishing rule?

Thx JP
