Incorporated the wired environment, the solution can apply Backup WAN and Load Balancing features to various applications while offering more mobility with Wi-Fi connectivity. The ZyWALL 2WG supports ZyNOS ICSA-certified IPSec VPN suitable for deployments from remote sites to the central server. As data encryption over the Internet ensures secure transmission between two sites without expensive leased lines, global interconnectivity can be achieved at a minimal cost. Thanks to the Redundant IPSec VPN feature, the ZyWALL 2WG’s dialup client will keep the connection running even the primary VPN connection fails.

Based on Stateful Packet inspection and Denial of Service (DoS) technology, it provides the first-line defense against hackers, network intruders and other hazardous threats. The ZyWALL 2WG offers the Secure Zone technology that SOHO users can simply deploy access servers in a DMZ zone separated from the trusted local network (LAN). The DMZ zone and WLAN zone have their own DHCP service, and all zones are securely segregated by firewall rules.
