Introducing the ZyWALL
This chapter gives an overview of the ZyWALL. It explains the front panel ports,
LEDs, introduces the management methods, and lists different ways to start or
stop the ZyWALL.
1.1 Overview and Key Default Settings
The ZyWALL is a comprehensive security device. Its flexible configuration helps
network administrators set up the network and enforce security policies efficiently.
In addition, the ZyWALL provides excellent throughput, making it an ideal solution
for reliable, secure service.
The ZyWALL’s security features include VPN, firewall, anti-virus, content filtering,
IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and
Protection), and certificates. It also provides bandwidth management, Instant
Messaging (IM) and Peer to Peer (P2P) control, NAT, port forwarding, policy
routing, DHCP server and many other powerful features. Flexible configuration
helps you set up the network and enforce security policies efficiently. See
Chapter

The front panel physical Gigabit Ethernet ports (labeled 1 , 2 , 3 , and so on) are
mapped to Gigabit Ethernet (ge) interfaces. By default 1 is mapped to ge1 , 2 is
mapped to ge2 and so on.
1.2 Rack-mounted Installation
The ZyWALL can be mounted on an EIA standard size, 19-inch rack or in a wiring
closet with other equipment. Follow the steps below to mount your ZyWALL on a
standard EIA rack using a rack-mounting kit. Make sure the rack will safely
support the combined weight of all the equipment it contains and that the position
of the ZyWALL does not make the rack unstable or top-heavy. Take all necessary
precautions to anchor the rack securely before installing the unit.
Note: Leave 10 cm of clearance at the sides and 20 cm in the rear.
