IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and
Protection), and certificates. It also provides bandwidth management, Instant

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.
