The DrayTek Vigor 3300 series routers combine VPN enhancements like robust firewall, WEB content filtering, Guaranteed Bandwidth, remote management and administrative functions to meet increasing demands for higher security and reliability in today's broadband environment. 

The DrayTek Vigor 3300 Security router provides additional IPSec VPN benefits that achieve highly scalable, confidential e-business objectives including branch office interconnectivity and remote access applications. By deploying the latest versions of encryption accelerators (i.e., DES/DES3-SHA-1/HMAC-MD-5), the DrayTek Vigor 3300 series routers affords low latency and higher performance IPSec VPN. 

The series'robust firewall offers a rich suite of security features like stateful packet inspection (i.e., examines the contents of individual packets at ALL layers of the OSI stack), access control, packet filtering, blocks intrusions/attacks and Denial of Service (DoS). Additional protection is provided via programmable integrated content filtering that blocks inappropriate WEB content for home or business environments. 

The QoS function (Quality of Service) ensures prioritized, dedicated bandwidth, controlled jitter and latency and reduced packet-loss characteristics.Load balancing or redundancy configurations provide reliable, un-interrupted traffic flows. Bandwidth can be increased (up to 400mbps) and traffic can be shared using multi-port WAN connections via the load balance feature. Simple re-configuration of WAN ports easily provides redundant, back-up capability. 

Optional 4/8 port VoIP modules provide connection with any PBX, key system or simple analog phone. 

The load balancing and high availability applications improve the network performance, scalability, reliability in Internet network and infrastracture utilization. 

The SNMP-based of DrayTek VigorCMS is the management software to offers an easy way to remotely set up configurations, update system status, display alarm events, monitor system behaviors, perform diagnostics and download firmware and email attacking alert. For installation, status monitor, and management of DrayTek Vigor 3300 series of routers, it will be easily accomplished through a built-in Web user interface or Telnet command line interface.
