Always-on Internet Connection
Enjoy effective, always-on Internet sharing for all the PCs in your office thanks to load-balancing delivered by two integrated broadband WAN ports to ensure optimal bandwidth sharing, and provide network redundancy in case one of the Internet services fails. The BiGuard 50G offers flexible WAN connectivity via Cable, XDSL, or FTTX for video conferencing, data transmission, VoIP and bandwidth-consuming applications. Load balancing provides the ability to distribute the outgoing traffic across the two connections, and meet growing business needs requiring more bandwidth and network scalability so you can offer users Internet-business applications. The Auto fail-over feature can be configured for a second connection to assure redundant connectivity when the primary line fails.

Mobility and Double-layer Protection
Set up a secure wireless environment with the integrated 802.11g AP for quick and easy access with data encryption. Wireless Protected Access (WPA-PSK/WPA2-PSK) and Wired Equivalent Privacy (WEP) support ensures high-level data protection and WLAN access control. If your network requires wider coverage, the built-in Wireless Distribution System (WDS) repeater function allows you to expand the wireless network without using any wires at all. In addition, rich firewall security features such as SPI, DoS attack prevention and URL content filtering are integrated to provide unparalleled protection for Internet access. Furthermore, the firewall function provides e-mail alert service to notify you whenever attacks occur.

Virtual Private Network Support
You can establish private encrypted tunnels over the public Internet using the BiGuard 50G's support for IPSec and PPTP VPN protocols to ensure that data is transmitted securely among multiple sites, such as branch office or remote dial-up. The VPN feature supports up to 50 simultaneous IPSec VPN tunnels and 32 simultaneous PPTP VPN tunnels.

Traffic Prioritization and Bandwidth Management
Manage your bandwidth and prioritize data transfer effectively with the Quality of Service (QoS) feature which gives full control over the traffic of any type of data. Thus, important data and bandwidth-consuming applications such as video conferencing, customer information or FTP sharing, can move through the router at instantaneous speed, even when there is a heavy load. The speed for inbound and outbound data passed through the router can be controlled to ensure that users do not saturate the bandwidth with their browsing activities.
