DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router - Overview

DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router - Robust & Comprehensive Firewall

As with previous DrayTek firewalls, security is taken seriously on the Draytek Vigor 2820n Series. The DrayTek Vigor 2820n ADSL2+ Wireless-N 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. Wireless, Ethernet and VPN on the DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router 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 2820n ADSL2+ Wireless-N Firewall Router 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 2820n ADSL2+ Wireless-N Firewall Router - Dual-WAN Load Balancing & Backup As well as the primary ADSL interface, the Draytek Vigor 2820n 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 2820n ADSL2+ Wireless-N Firewall Router's secondary interface can be used either for WAN-Backup or load balancing. DrayTek Vigor 2820n ADSL2+ Wireless-N 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 2820n ADSL2+ Wireless-N Firewall Router's secondary Internet access. When normal services is restored to your primary ADSL line, all traffic is switch back to that by the DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router. If you don't have ADSL, the DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router's Ethernet WAN port can instead be used as your primary/only Internet connection (using NAT) so the same DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router can be used for either ADSL or Ethernet Internet connections. The DrayTek Vigor 2820n ADSL2+ Wireless-N 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 2820n ADSL2+ Wireless-N 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 2820n ADSL2+ Wireless-N Firewall Router - Wireless LAN

The Draytek Vigor 2820n Series features the latest 802.11n Draft 2.0 wireless LAN specification and has been certified by the WiFi alliance for cross compatibility and WiFi compliance (including WPA/WPA2 and WMM).

802.11n Draft 2.0 provides a total wireless bandwidth of up to 300Mb/s using new methods such as packet aggregation and channel bonding. Throughput depends on your own environment (factors such as obstructions, number of hosts and distance all make a significant difference), but actual transfer speeds of 100Mb/s are achievable (based on our real world tests). In addition, 802.11n Draft 2.0 provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO technology and the Draytek Vigor 2820n's triple-antennae diversity arrangement. This offset arrangement of aerials on the DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router provides offset paths between hosts so that interference can be overcome.

Wireless Security is comprehensive too; the Draytek Vigor 2820n Series provides several independent levels of security including encryption (up to WPA2), authentication (802.11x) and methods such as MAC address locking and DHCP fixing to restrict access to authorised users only. The DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router's Web interface lets you see how many and which clients are currently connected as well as their current bandwidth usage. An 'instant' block lets you disconnect a wireless user temporarily in case of query.

Your laptop PC's built-in wireless may not support 802.11n Draft 2.0 wireless, in which case you will need to add a new wireless LAN interface such as the DrayTek N61 USB adaptor.

For specialist coverage applications, optional aerials can be used with the Draytek Vigor 2820n to potentially increase the range of wireless coverage (depending on enviroment) or provide directional coverage in order that your wireless transmission is focused and concentrated into one direction only, for example into a room or across open space.

Important Note : Wireless performance (speed and range) always depends on your specific environment and will vary considerably. Factors affecting performance include wireless traffic, other networks nearby, site construction, walls, ceilings and other electronic equipment nearby. The product may not be upgradable to future 802.11n Draft standards or be compatible with products from other manufacturers. Speeds quoted are the maximum wireless capacity, including RX/TX capacity, protocol overheads and all clients/hosts connected.

DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router - WDS

DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router - Wireless LAN WDS Facility

Note : WDS requires a free firmware upgrade, ETA March 2008.

Draytek Vigor 2820n models equipped with Wireless LAN support a system called WDS (Wireless Distribution System) which enables you to use the wireless capability to bridge to another network, within wireless range. You need an additional compatible wireless router for this of course. Here is a simple example:

With WDS bridging, both networks should be within the same logical IP subnet (IP address range). Once set up, all of the PCs on both sides of the link can access each other, across the wireless bridge. Local wireless devices such as a laptop can continue to use their local access point.

An additional mode, as shown above, called 'repeating', allows you to set up a third station. In the diagram below, the DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router at 'B' is set up in repeating mode, relaying traffic between LANs at A and C. Therefore, all three physical networks can communicate with each other over the wireless links.

DrayTek Vigor 2820n ADSL2+ Wireless-N Firewall Router - 3G

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

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