Network architecture
All SMA 6200/7200 appliances can be set up in either a dual
interface or single interface configuration, also known as dual-
homed and single-homed.
In either configuration, appliance management with AMC is
accomplished by accessing the internal (X0) interface.
This guide steps you through a basic single-homed interface
configuration. For the highest level of security, performance,
and in cluster mode, Dell recommends a dual-homed
configuration. Refer to the Deployment Planning Guide and
SMA Administration Guide for further information.
If you are installing a cluster, refer to the SMA Administration
Guide.
Dual-homed configuration (internal
and external interfaces)
One network interface is used for external traffic (that is, to
and from the Internet), and the other interface is used for
internal traffic (to and from your corporate network).

(internal interface)
A single network interface is used for both internal and
external traffic. In this configuration, the appliance is usually
installed in the demilitarized zone (or DMZ, also known as a
perimeter network).
