Getting to Know Your ZyWALL
This chapter introduces the main features and applications of the ZyWALL.
1.1 The ZyWALL 100 Internet Security Gateway
The ZyWALL 100 is the ideal secure gateway for all data passing between the Internet and the LAN for
small to medium sized businesses.
By integrating NAT, firewall and VPN capability, ZyXEL’s ZyWALL 100 is a complete security solution
that protects your Intranet and efficiently manages data traffic on your network.
The embedded web configurator is easy to operate and totally independent of the operating system platform
you use.
1.2 Physical Features of The ZyWALL 100
Auto-negotiating 10/100 Mbps Ethernet LAN
The LAN interface automatically detects if it’s on a 10 or a 100 Mbps Ethernet.
Auto-negotiating 10/100 Mbps Ethernet DMZ
Public servers (Web, FTP, etc.) attached to the 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.
10/100 Mbps Ethernet WAN
The 10/100 Mbps Ethernet WAN port attaches to the Internet via broadband modem or router
Backup WAN
The Dial Backup port can be used in reserve as a traditional dial-up connection when/if ever the broadband
connection to the WAN port fails.
Time and Date
The ZyWALL has a Real Time Chip (RTC) that keeps track of the 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.
