DMZ Ports
Public servers (Web, FTP, etc.) attached to a DeMilitarized Zone (DMZ) port are visible to the
outside world (while still being protected from DoS (Denial of Service) attacks such as SYN
flooding and Ping of Death) and can also be accessed from the secure LAN.
LAN/DMZ Interface
The ZyWALL provides four LAN ports that can also function as virtual DMZ ports. You can
configure the ports as LAN or DMZ ports by changing the port role settings in the LAN or
DMZ screen through the Web configurator.
Dual Auto-negotiating 10/100 Mbps Ethernet WAN
The 10/100 Mbps Ethernet WAN ports attach to the Internet via broadband modem or router.
You can use a second connection for load sharing to increase overall network throughput or as
a backup to enhance network reliability.
The 10/100 Mbps auto-negotiating Ethernet ports allow the ZyWALL to detect the speed of
incoming transmissions and adjust appropriately without manual intervention. It allows data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network. The ports are also auto-crossover (MDI/MDI-X) meaning they
automatically adjust to either a crossover or straight-through Ethernet cable.

Dial Backup WAN

The dial backup port can be used in reserve as a traditional dial-up connection when/if ever the
WAN 1, 2 and traffic redirect connections fail.
Time and Date
The ZyWALL allows you to get the current time and date from an external server when you
turn on your ZyWALL. You can also set the time manually. The Real Time Chip (RTC) keeps
track of the time and date.
