CHAPTER 1
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
2 on page 37 for a more detailed overview of the ZyWALL’s features.
The ZyWALL provides excellent throughput with the reliability of dual WAN Gigabit
Ethernet ports and load balancing. You can also use a 3G cellular USB (not
included) for a third WAN connection.
The ZyWALL lets you set up multiple networks for your company. The De-
Militarized Zone (DMZ) increases LAN security by providing separate ports for
connecting publicly accessible servers. The ZyWALL also provides two separate
LAN networks. You can set ports to be part of the LAN1, or DMZ. Alternatively, you
can deploy the ZyWALL as a transparent firewall in an existing network with
minimal configuration.
