Draytek Vigor2820Vn Dual WAN ADSL 2/2+ Modem/Router Security Firewall with VoIP

The Draytek Vigor2820Vn is an ADSL2+ IEEE802.11n Compliant ( Draft 2.0 ) Modem Router Security Firewall device with a 2nd Ethernet WAN port (Dual WAN). This 2nd WAN can connect to DSL/Cable modem or fiber media converter for policy-based load-balancing, fail-over and Band Width on Demand (BoD); it also features advanced bandwidth control mechanisms such as IP-layer QoS, NAT Session Limitation, Bandwidth Borrowed, etc., to provides you with easy, flexible and reliable access control and bandwidth management.

The SPI (Statefull Packet Inspection) firewall uses Object-Based design to make setting of the firewall policies a snap! The CSM (Content Security Management) feature allows more precise and efficient access control for URL/Web Content Filtering, IM (Instant Messenger) and P2P (Peer-to-Peer) applications.
