Vigor 2820 Series ADSL Router Firewall

The Vigor 2820 series is DrayTek's flagship premium ADSL router/firewall family. Packed with features, the Vigor 2820 offers truly comprehensive ADSL connetivity and security. PC Pro says "For business, it's an obvious choice"

Compatible with all variants of ADSL (including ADSLMax, ADSL2+ and Annex M) 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 LAN 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.

Robust & Comprehensive Firewall

Security is taken seriously on the Vigor 2820 Series. The 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 are also protected by various protection systems (see later). The object-based firewall allows even more setup flexibility, 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 or data types, blocking specific web sites, blocking IM/P2P applications or other potentially harmful or wasteful content. Using DrayTek's new GlobalView service, you can block whole categories of web sites (e.g. gambling, adult sites etc.), subject to an annual subscription to the Globalview server, which is continuously updated with new or changed site categorisations or sites which have become compromised (such as infected with Malware). Learn more about DrayTek Web Content Filtering here. A 30-Day free trial of Globalview can be activated on your router.

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 contingency (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 (using NAT) 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. In addition you can instead connect a compatible analogue modem to use analogue dial-up connections for failover in the event of your broadband failing. See seaprates page for more details on both 3G and analogue dial-up. On the ISDN-equipped model (Vigor2820VSn) you can instead use ISDN for dial-in or dial-out connectivity and backup. Note : For WAN failover you can use only one method at a time, e.g. Ethernet, 3G or analogue connections.

Wireless LAN ('n' models only)

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

802.11n 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 provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO technology and the Vigor's triple-antennae diversity arrangement. This offset arrangement of aerials provides offset paths between hosts so that interference can be overcome.

Wireless Security is comprehensive too; the Vigor 2820 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 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. The Wireless VLAN facility allows you to isolate wireless clients from each other or from the 'wired' LAN.

The Multiple SSID features enables you to have up to four distinct or common virtual wireless access points. For example, you could have one for company usage, with access to your company LAN and another for public access which allows internet surfing only. Setting up wireless security is made easier thanks to the WPS feature (WiFi protected setup) whereby your client PC can get it's security keys by pressing a button on the front of the router.

If your laptop PC's built-in wireless doesn't support 802.11n wireless, you can use the optional Vigor N61 USB adaptor. Click on 'accessories' for details.

For specialist or more demanding coverage applications, optional aerials can be used with the Vigor 2820 to potentially increase the range of wireless coverage (depending on enviroment) or provide directional coverage in order that your wireless transmission is focussed and concentrated into one direction only, for example into a room or across open space. With the increasing popularity of wireless LANs, you will want to choose the least congested wireless channel (Nos. 1-13) for yours. The Vigor can scan and provide a list of all devices in the vicinity so that you can choose the best channel (see screenshot below).

Wireless LAN WDS Facility

Vigor 2820 'n' models support 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 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.

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. Speeds quoted are the maximum wireless capacity, including RX/TX capacity, protocol overheads and all clients/hosts connected.

Voice-over-IP Features ('Vn' Model)

The Vigor 2830Vn provides two analogue phone ports and an analogue line port provide full PSTN and VoIP integration on the same phones, via both the Internet and your regular analogue line. The two phones can be used independently and simultaneously for both incoming and outgoing calls.

As well as the two telephone ports, a third port, the Analogue Line port, connects into your regular analogue line (PSTN/POTS*). This then gives the telephones access to your analogue line to allow you to make calls as well as your VoIP facility (you can select the PSTN line instead of VoIP by dialling #0). Incoming calls are automatically switched through to your telephone(s) (either one or both) so that each phone can be used for both VoIP and POTS calls. Both telephones plugged into your router have access to VoIP and your analogue line. In addition, using the 'Digit-Map' facility you can set rules about particular call destinations using either the POTS line or your SIP/VoIP service. For example, local calls can be routed via your PSTN line (if you have a free calls package for example) whereas international calls can go via your preferred VoIP provider; there is flexibility to have several digit-map rules.

As well as connecting with a SIP/VoIP gateway directly (such as DrayTEL), the vigor2830Vn can register its phones as extensions on a remote IP PBX, such as DrayTek's Vigor IPPBX products, so this is an idea teleworker solution.

*POTS = Plain Old Telephone Service - The traditional analogue phone voice line in your home/office, e.g. B.T. That line may also be carrying your ADSL data signal.

3G Cellular Data Features

The 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 Wireless LAN equipped models of the Vigor 2820 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 router's PSU, but this could be from a mobile generator or equivalent so you need to plan for this.

There is more information about DrayTek 3G solutions here.

Note: DrayTek have no control over local network/provider operations, changes in network facilities/tarrifs nor make any claim over specific network compatibility. Please assure yourself that the router will be compatible with your chosen cellular network and provider and that you have adequate signal coverage before committing to any contract term. Please also ensure that your chosen provider and the tariff allows access to all of your required applications (e.g. VPN, VoIP, Messaging etc.) as many packages exist, some blocking certain data types.

Network Attached Storage (NAS)

The Vigor 2820 Series's USB port can also be used to add storage memory to the unit in the form of a USB memory key (as shown right) or for higher capacity a USB hard drive (normally requires its own power). The Vigor 2820 then provides FTP access file uploading/downloading which can be from the local LAN or from anywhere on the Internet - ideal for a simple to deploy file depository. Access can be 'public' or using usernames and passwords, each of which can have their own directories and/or file access rights. As well as FTP, file sharing is available as a Windows 'network drive'. Using Internet Explorer, you can view the contents of the USB drive connected to the Vigor 2820 and read or write files.

The NAS facility uses any FAT32 formatted device (includes USB memory sticks, USB hard drives etc.) and supports a transfer rate of 12Mb/s.

Note : This feature is available ETA, Summer 2009.

Dial-Up Backup (Analogue)

If you rely on your Internet connection, you can allow for ADSL failure by adding dial-up backup to your Vigor2820. Dial-up backup uses a 'good old-fashioned' analogue modem to dial a backup ISP in the event your ADSL line or ISP fails, either temporarily or for an extended period. The add-on analogue modem (seen below) provides 'V92' connections (up to 52000bps downstream speed) which is somewhat slower than your broadband connection but certainly usable for light web browsing, email and all other online activities which you really can't do without.

The Vigor 2820 will detect when your ADSL connection fails and automatically start the dial-up connection using the modem which is connected to the router's USB port. Once ADSL service is restored, the router will hang-up the dial-up call. Note : The modem is an optional accessory, not included with the router.

There are lots of 'free' dial-up ISPs in the UK which you can use in an emergency; you pay only for the call costs (normally 0845 Lo-Call Rate). Alternatively, you can subscribe to an ISP who offers a 'FRIACO' service, where your dial-up calls are free of charge, for a monthly subscription.

Vigor2820 with ADSL and Analogue modem attached

Analogue Dial-Up on its own As well as backup to your ASDL connection, you can use dial-up connection permanently without ADSL line. This is ideal for shared Internet access, or wireless access to the Internet in temporary locations where an ADSL line isn't available, and an alternative to the 3G modem solution also available on the Vigor 2820.

Vigor2820 with Analogue dial-up modem

For analogue (dialup) backup you require the optional AFM-102 modem.

Vigor 2820Vn Recommended by Personal Computer World " More than your average Internet router. The Vigor2820Vn offers a lot of really useful features of value to small business, which aren't found on most other Internet routers. We had no trouble getting our Vigor2820Vn to work the way we wanted. The hardware is well made and the Vigor2820Vn has a lot to interest the small-business buyer. Recommended." Personal Computer World, September 2008

Vigor 2820Vn Recommended by Techworld "Amazing range of features in one box – dual WAN, 3G, dual VoIP, Gigabit Ethernet, 802.11n, and oodles of security – the lot. It even has a rack-mounting kit......This is probably the most featured wireless router Techworld has ever tested and it sets a high standard for others to match. Its major selling point is that should the primary link go down, it can fall back to a second, an unusual feature in a box costing well under £200. The most likely setup for this would be the WAN or ADSL line going down and the 3G stepping in. There has been a trickle of other cheap routers that can do this, but none that manage it without compromising on other features and adding VoIP/PSTN integration to boot. Recommended." Techworld, July 2008

Vigor 2820n Recommended by Trusted Reviews "DrayTek's broadband routers have traditionally offered more for your money than most competing products and the latest Vigor2820n continues this tradition with a range of features that belies its modest price tag.....The Vigor2820n is offering a bumper bundle of features making it highly appealing to small businesses looking for a sophisticated broadband router. General security and wireless features are particularly good......The router is well built with all its ports arranged across the front panel so that they're easily accessible if the router is mounted in a standard 19in rack....Wireless features are a cut above the rest. Overall Score: 9 our of 10. Recommended." Trusted Reviews, May 2008

Vigor 2820 Series Recommended by IT Reviews "We tried the Vigor 2820 for several days and had no problems whatsoever. Performance was good and, if it's anywhere near as reliable as previous Vigor routers, the 2820 will be popular with small businesses and others looking for a little bit more than the average router has to offer.  The 'Rolls Royce' of the Internet router world, the Draytek Vigor 2820 offers multiple ways of connecting to the Internet, integrated backup and load balancing facilities, together with extensive wired and wireless networking facilities. There are more security features than you can shake a stick at, a hardware VPN server comes as standard and VoIP is an optional add-on. It's not cheap but it's got it all. Recommended." IT Reviews, August 2008
