802.11g Dual-WAN Security Gateway for SMB
The BiGuard 50G boasts a dual-WAN gateway function that also delivers a secure wireless environment
via a built-in 802.11g AP, allowing you to quickly and easily set up a wireless network for added office
mobility. Always-on Internet access is delivered through two connections and an auto fail-over feature that
can swap between interfaces to ensure constant communication. This product is a standalone security
gateway solution designed for SMB users looking for enterprise-level access and security. Safe Internet
access and browsing are delivered by the incorporated firewall with web content filtering and
comprehensive security. Effective load-balancing, QoS and easy administration ensure that office users
enjoy a smooth Internet experience while making sure that important data receive bandwidth priority. For
on-the-road users, up to 50 secure IPSec VPN tunnels enable safe data transmission between the head
office and remote sites.
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 Wireless Encryption Protocol
(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
4 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.
