ZyXEL Unveils 3G and 802.11 a/b/g Wireless Broadband Security Appliance

Hsinchu, March 9, 2007 -- ZyXEL Communications Corp. (TSE: 2391) today announced its new ZyWALL 2WG, a mobile broadband security appliance for Internet access using cellular phone services, will be shown at the ZyXEL booth (Hall 15 D05) in Hannover CeBIT, March 15-21, 2007. The ZyWALL 2WG equips small office users and remote mobile workers with instant secure broadband Internet access anywhere. Designed with feature integration, user mobility, flexibility and security in mind, the new ZyWALL 2WG is an ideal solution for tradeshows, outdoor environment or difficult-to-wire locations.

The ZyWALL 2WG is a mobile Internet security appliance with integrated firewall, VPN, wireless LAN and broadband Internet access in 3G networks.  By inserting a 3G data card into the extension slot, the ZyWALL 2WG provides instant broadband Internet access in a 3G network.

The ZyWALL 2WG can use the 3G network connection as the primary or backup connection for Internet access and load-balancing for dual WAN applications. Currently, the ZyWALL 2WG supports the Sierra Wireless 3G data PCMCIA card for EDGE, GPRS, UMTS and HSDPA networks.

For wired connections, the ZyWALL 2WG still supports WAN backup, load balancing, fail-over and fail-back technologies. For  wireless connections, the ZyWALL 2WG offers the flexibility of dual band technology with 802.11a/b/g for LAN users. The built-in security features include SPI firewall, DoS prevention, IPSec VPN and content filtering for state-of-the-art protection against Internet attacks.

The ZyWALL 2WG features the Secure Zone technology that allows SOHO/SB users to deploy access servers in a DMZ zone, separate from the trusted local network (LAN). The ZyWALL 2WG provides independent DHCP services for the DMZ and WLAN zones and all zones are securely protected by firewall rules.

ZyXEL ZyWALL 2WG is scheduled to be available at the end of March and can be ordered via ZyXEL's global sales network of system integrators and value-added resellers. To find a ZyXEL distributor nearest to your location, visit the information site at http://www.zyxel.com/web/where_tobuy.php
