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 designed for Small and Medium Businesses
(SMB) and branch offices. The ZyWALL's security features include VPN, firewall, 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
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 card (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, WLAN, or DMZ. Alternatively, you can deploy the ZyWALL as a transparent
firewall in an existing network with minimal configuration.
