Hsinchu, Taiwan, May 30, 2001 -- ZyXEL Communications Co. (TAI:2391.TW), a pioneer manufacturer and supplier of DSL CPE, today announced its new Internet security gateway, the ZyWALL 100. Integrated with robust Firewall, VPN and enhanced network management features, the ZyWALL 100 is tailored for businesses to provide a complete security solution to protect the users office Intranet and efficiently manage data traffic on the network.

Given the complexity of today's networks infrastructure, businesses are faced with the connectivity challenge of a fast growing community of mobile remote users and branch offices. The ZyWALL 100 allows companies to establish up to 100 IPSec (IP Security) VPN connections with business partners and remote branch offices. VPN uses data encryption and the Internet to provide transparent and secure communications between two or more sites; hence greatly reducing the expense of leased lines.

Furthermore, the ZyWALL 100's DMZ (De-Militarized Zone) port allows users on the Internet to access information on multiple public servers, such as web or mail servers, while maintaining the security of the private LAN.

Based on ICSA certified ZyXEL Network Operating System (ZyNOS), the ZyWALL 100 acts as a secure gateway between the Internet and the LAN. With stateful inspection, fields of packets are compared to packets that are already known and trusted, hence preventing theft, destruction, and modification of data and log events from outside hackers and vandals on the Internet. The ZyWALL 100 is pre-configured to automatically detect and thwart DoS attacks. It also supports TCP/UDP inspection, real time alerts, reports and logs.

With ZyXEL's Internet Content Filtering, network administrators can establish and enforce acceptable Internet access policies tailored to their needs. Built-in Internet Content Filtering enables the ZyWALL 100 to block certain Website features, as well as monitor and control users to prevent visits to improper or nonproductive Web content.

The ZyWALL 100 offers an optional IEEE 802.11b compliant wireless LAN solution which allows users to work anywhere in the coverage area and enjoy the convenience of mobility.

Availability & Warranty
The ZyWALL 100 Internet Security gateway is scheduled to be available in the third quarter of 2001. It will be distributed through ZyXEL's global network of authorized distributors. ZyXEL offers a warranty period of up to 2 years covering materials and workmanship.
