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.
