DrayTek Vigor 2820 ADSL2+ Router

DrayTek Vigor 2820 ADSL2+ Firewall Router - Overview

Draytek Vigor 2820 ADSL2+ Router Firewall

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

Compatible with all variants of ADSL (include ADSLMax and ADSL2+) the Draytek 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's WAN side provides high speed connectivity for your server (or uplink to a larger Ethernet Switch). DrayTek Vigor 2820 ADSL2+ Firewall Router Security features include content filtering, web application controls and a new object based firewall management system.

DrayTek Vigor 2820 ADSL2+ Firewall Router - Robust & Comprehensive Firewall

As with previous DrayTek firewalls, security is taken seriously on the Draytek Vigor 2820 Series. The DrayTek Vigor 2820 ADSL2+ Firewall Router's firewall features measures for protection against attacks including DoS (Denial of Service) attacks, IP-based attacks and access by unauthorised remote systems. The DrayTek Vigor 2820 ADSL2+ Firewall Router's 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's 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.), subject to subscription

DrayTek Vigor 2820 ADSL2+ Firewall Router - Dual-WAN Load Balancing & Backup

As well as the primary ADSL interface, the Draytek 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's secondary interface can be used either for WAN-Backup or load balancing.

DrayTek Vigor 2820 ADSL2+ Firewall Router's 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's Ethernet WAN port can instead be used as your primary/only Internet connection (using NAT) so the same DrayTek Vigor 2820 ADSL2+ Firewall Router can be used for either ADSL or Ethernet Internet connections.

The DrayTek Vigor 2820 ADSL2+ Firewall Router's USB port provides an alternative connection method (Firmware Upgradable) 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 DrayTek Vigor 2820 ADSL2+ Firewall Router's 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. This feature requires a firmware upgrade.

Note : For WAN2 you can use either a Ethernet or USB 3G connection but not both at the same time.

DrayTek Vigor 2820 ADSL2+ Firewall Router - 3G

DrayTek Vigor 2820 ADSL2+ Firewall Router - 3G Cellular Data Features (ETA Feb/March 2008)

The Draytek Vigor 2820 Series's USB port can host a compatible 3G modem or cellphone for access to the cellular network for full Internet Access. Most UK networks now provide high speed HSDPA data connections at up to 3.6Mb/s download speed. The 3G connection can be used as your primary/only Internet access, or as backup to your main ADSL line connection. This is not only ideal for homes or offices which don't want to pay fixed line + broadband rental, but also for temporary locations, or those to where fixed lines aren't available.

With the Draytek Vigor 2820 series, your local users can be connected wirelessly to the DrayTek Vigor 2820 ADSL2+ Firewall Router, so instant free 'hotspots' can be deployed quickly and easily. Mains power is required for the DrayTek Vigor 2820 ADSL2+ Firewall Router's PSU, but this could be from a mobile generator or equivalent so you need to plan for this.
