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 DeMilitarized 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.
