Keep this in mind when planning your deployment. It is a good idea to do some
research based specifi cally on your target uses of ISA Server as well as your estimated

org forums. However, in order to get good answers based on your capacity
needs, you should do some baselining of your environment to make sure that
your estimated workload is not just a wild guess.

It is always a good idea to consider not only the ISA Server confi guration, but
the details around it as well. Whenever possible the ISA Server should be
deployed inline to provide the highest level of security. This is not a best practice
that is unique to ISA Server, but to all fi rewalls. Although ISA Server and many

behind it. In this scenario, we have two NICs to confi gure.
The trick is that we only want to confi gure a single default gateway and a common
DNS server setting for all interfaces.
