DrayTek Vigor 2820

DrayTek Vigor 2820   DrayTek Vigor 2820n  DrayTek Vigor 2820Vn

The Vigor 2820 series is DrayTek's premium ADSL and broadband router/firewall family, featuring an entirely new stylish case design and new DrayOS 3 operating system. Packed with features, the Vigor 2820 offers truly comprehensive ADSL connetivity and security.

Compatible with all variants of ADSL (include ADSLMax and ADSL2+) the Vigor 2820 can also be used for cable-modem and leased line applications thanks to its additional WAN port (Ethernet). A Gigabit Ethernet port on the WAN side provides high speed connectivity for your server (or uplink to a larger Ethernet Switch). Security features include content filtering, web application controls and a new object based firewall management system.

The Vigor2820 is an ADSL2+ router with 2nd Ethernet WAN. This 2nd WAN can connect to DSL/Cable modem or fiber media converter for policy-based load-balance, fail-over and BoD, it also features advanced bandwidth control mechanisms such as IP-layer QoS, NAT Session Limitation, Bandwidth Borrowed, etc., to allow easy, flexible and reliable access control and bandwidth management.


As with previous DrayTek models, security is taken seriously on the Vigor 2820. The firewall features measure for protection against attacks including DoS (Denial of Service) attacks, IP-based attacks and access by unauthorised remote systems. Wireless, Ethernet and VPN are also protected by various protection systems (see later). A new DrayTek object-based firewall allows even more setup flexibility than ever, enabling you to create combinations of users, rules and restrictions to suit multi-departmental organisations.

Content control features of the firewall allow you to set restrictions on web site access, blocking download of certain file types, blocking specific web sites, blocking IM/P2P applications or other potentially harmful or wasteful content. Using the SurfControl site categorisations enable you to block whole categories of web sites (e.g. gambling, pornography etc.)

Dual-WAN Load Balancing & Backup

As well as the primary ADSL interface, the Vigor 2820 features a secondary WAN port for Internet access. This is an Ethernet interface and can connect to a second ADSL modem, cable modem or any other Ethernet-based Internet feed. The secondary interface can be used either for WAN-Backup or load balancing.

WAN-Backup provides contingenry (redunancy) in case of your primary ADSL line or ISP suffering temporary outage). Internet Traffic will be temporarily routed via the secondary Internet access. When normal services is restored to your primary ADSL line, all traffic is switch back to that.

If you don't have ADSL, the Ethernet WAN port can instead be used as your primary/only Internet connection so the same router can be used for either ADSL or Ethernet Internet connections.

The USB port provides an alternative connection method for Internet backup by connecting to a compatible USB modem (or cellphone) for access to the high speed 3G cellular networks from UK providers such as Vodafone, Orange, 3 and T-Mobile. If you don't have ADSL at all, the USB/3G access method can be used as your primary/only Internet connection, ideal for temporary locations, mobile applications or where broadband access is not available.

 DrayTek Vigor 2820 VPN Firewall Application :

With hardware-based implementation of the VPN protocol, the Vigor2820 supports up to 32 VPN tunnels using advanced protocols such as IPSec / PPTP / L2TP / L2TP over IPSec with AES / DES / 3DES for encryption and MD5 / SHA-1 for authentication.

The SPI firewall uses Object-Based design to make setting of firewall policies easy. The CSM feature allows more precise and efficient access control for URL / Web Content Filtering, IM and P2P applications.
