ZyWALL USG 100/200 Series User’s Guide

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.

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, 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 

 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 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.

You can insert a wireless LAN card into the PCMCIA/CardBus slot to add an IEEE 802.11b/
g-compliant wireless LAN. 

Configure the ZyWALL USG 200’s OPT Gigabit Ethernet port as a third WAN port, an 
additional LAN1, WLAN, or DMZ port or a separate network.
