The Demilitarized Zone (DMZ) port is used for public servers, such as
Web or FTP servers. Machines attached to this port are visible from the
WAN port, but are still protected from hacker attacks. Users on the
secure LAN port can also access servers on the DMZ port.

Network Supervisor automatically discovers up to 1500 network devices
and shows devices and connections on a graphical display. Network
managers can view network activity, monitor stress and set thresholds
and alerts. This information helps to provide the most efficient,
cost-effective use of network resources.
Version 3.0 and later releases add significant extra functionality designed
to detect network inefficiency and optimize network performance.
Features include support for related and recurring events, user definable
reports, auto-alerting using pager or SMS messages and simple updates
from the 3Com web site.
