The Vigor 2920 series is a dual-WAN port Firewall Router with excellent performance to run both WAN interfaces simultaneously.
Robust And Comprehensive Firewall
Security is a major feature Vigor 2920 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 DrayTek object-based firewall allows vast 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 types, blocking specific web sites, blocking IM/P2P applications or other potentially harmful or wasteful content. Filtering using web site categorisations enable you to block whole categories of web sites (e.g. gambling, adult sites etc.), subject to subscription.
Dual-WAN Load Balancing And Backup
Either (or both) Ethernet WAN ports on the Vigor 2920 can be connected to an ADSL modem, cable modem or any other Ethernet-based Internet feed. When you are using both ports, the secondary interface can be used either for WAN-Backup or load balancing.
WAN-Backup provides contingency (redundancy) in cases of your primary feed 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.
In load-balancing mode, the Vigor 2920 will make use of both of your WAN feeds together, spreading your Internet traffic across both either as equally as possible or according to user-configurable rules. For example, you might want all of your VoIP traffic to be routed only through one ISP connection.
The Vigor 2920's 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, O2, Orange, 3 and T-Mobile. The 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.
Note : For WAN failover you can use only one method at a time, e.g. Ethernet, 3G.
Wireless LAN ('n' models only)
The Vigor 2920 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 Draft 2.0 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 2920 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 2920 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.

Wireless LAN WDS Facility
Vigor 2920 'n' models 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.
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.
3G Cellular Data Features
The Vigor 2920 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 2920 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.
The Vigor 2920 and 3G cellular modem setup is ideal for:
- Backup to your primary Internet feed (ADSL, cable etc.)
- Providing lower cost broadband than a fixed line solution
- Areas without fixed line broadband access
- Compatible with a wide range of 3G modems/phones
- Temporary Locations
- Mobile Homes
- Locations on the move - coaches, trains
- Fairgrounds & temporary exhibitions
- Outdoor locations (the router and modem itself must be indoors!)
- Disaster Planning & High Availability
Network Attached Storage (NAS)*
The Vigor 2920 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.
