1-2 Getting to Know Your ZyWALL
1.1.5 ZyWALL 100 Internet Security Gateway for Small to Medium
Businesses
The ZyWALL 100 offers the highest degree of functionality and security for business applications. It
supports up to 100 IPSec VPN connections and increases network security by adding a De-Militarized Zone
(DMZ) port for use with publicly accessible servers.
1.2 ZyWALL Features
The following sections describe ZyWALL features. Features vary by ZyWALL model.
1.2.1 Physical Features
Auto-negotiating 10/100 Mbps Ethernet LAN
The LAN interface automatically detects if it’s on a 10 or a 100 Mbps Ethernet.
Auto-crossover 10/100 Mbps Ethernet LAN
The LAN interface automatically adjusts to either a crossover or straight-through Ethernet cable. This feature
is not available on all models.
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. This feature is not available on all models.
10/100 Mbps Ethernet WAN
The 10/100 Mbps Ethernet WAN port attaches to the Internet via broadband modem or router. This feature is
not available on all models.
Backup WAN or Auxiliary
The Dial Backup or Auxiliary port can be used in reserve as a traditional dial-up connection when/if ever the
broadband connection to the WAN port fails. This feature is not available on all models.
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
(not available in all models).
