DrayTek Vigor 2820 ADSL2+ Security Firewall

Description

The Vigor2820 series is the ultimate ADSL2/2+ router with secondary WAN (for dual ISP feeds) which can connect to a DSL / Cable modem or fiber media converter for policy-based load-balance, fail-over and BoD ( Bandwidth on Demand ). The firewall remains versatile, with a new object-based rule management system. It also includes advanced bandwidth control mechanisms such as Bandwith Borrowed, NAT Session Limitation, IP-layer QoS, etc., to allow flexible, easy and reliable bandwidth management and access control.

The integrated twin-VoIP phone ports with POTS passthrough, 802.11n Draft 2.0 Wi-Fi, 3G connectivity and a new web content management system provide you with robust features which are highly configurable in terms of needs. The new case is optionally rack mountable for offices.
