1.2.1 Physical Features
LAN Port
The 10/100 Mbps auto-negotiating Ethernet LAN port allows 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 port is also auto-crossover (MDI/MDI-X) meaning it
automatically adjusts to either a crossover or straight-through Ethernet cable.
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.
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.
WLAN Ports
You can set some of the Ethernet ports to a WLAN port role. This allows you to connect
wireless LAN Access Points (APs) to extend the ZyWALL’s wireless LAN coverage area.
Dual Auto-negotiating 10/100 Mbps Ethernet WAN (single on the ZyWALL 5)
The Ethernet WAN ports connect 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. They allow data
transfers 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, (or WAN 1, 2) and traffic redirect connections fail.
