The Vigor 2800 is our ADSL router for Internet access, firewall, VPN and Ethernet switching. The Vigor2800 includes features such as VLAN, QoS, Content filtering, VPN support for up to 16 tunnels and a USB printer port and support for all current ADSL technologies. Parental control and Peer-to-peer software restriction (blocking of Messenger, file-sharing etc.) is also supported on the Vigor2800.
The Vigor2800's primary WAN interface (its link to the outside world) is its built-in ADSL modem; the RJ11 socket connects straight into your ADSL enabled line (normally via a Microfilter). The unit provides support for ADSL, ADSL2 and ADSL2+ standards. The ADSL2/2+ compatibility means that you can take advantage of those new standards for their higher speed and greater reach/robustness.
The Vigor2800i model offers all of the same facilities as the standard Vigor2800 model but has an ISDN interface in addition to ADSL. This can connect to any ISDN2e or BT Highway/Midband line. The ISDN interface provides dial-backup in the event of your main ADSL connection being interrupted. Alternatively, the ISDN interface can be used on its own (as your main Internet connection) if you do not have an ADSL feed to connect to the Vigor2800i. When operating on ISDN, the Vigor2800i can be used both for shared Internet access and direct-dial ISDN LAN-to-LAN Wide Area Networking (dial in teleworkers or dial-in/out branch links) at the same time (one function on each B channel).
As mentioned above, you can use the Vigor 2800's USB port as a WAN interface to a USB 3G (cellular) modem, supporting the latest 'HSDPA' networks. HSDPA provides connection at up to 3.4Mb/s - much faster than previous cellular GSM/GPRS systems. This enables you to provide broadband access anywhere in the UK (subject to network coverage) without needing fixed lines. This can be in a temporary office, a coach, hotel or anywhere you like and your users can then browse web sites or check there email with ease. The USB modem and SIM is not supplied with the router; you obtain that separately from your cellphone company. The following USB modems/phones are currently supported:
The Vigor2800 supports selectable QoS (Quality of Service). This enables you to select specific protocols/services to have guaranteed levels of your Internet bandwidth. For example, if you need POP3 email to have priority, you could specify that 50% of your download (or upload, or both) bandwidth is reserved for POP3 when required. When it's not being used by POP3, the bandwidth is available for all other regular traffic. The Vigor2800 is very flexible on QoS - you can set several groups of services to have different priorities and bandwidth reservations.
The USB port on the back of the router allows you to connect most standard USB based printers and then print to them from any Windows98SE/XP/2000 PC, using built-in O/S support from any application, thus not needing to have a particular PC be on to provide printer sharing to its peers.
A VPN (Virtual Private Network) is a method for using a public network (Internet) to carry private data between offices or from teleworkers to office. The Vigor2800 can act as a VPN concentrator (endpoint) for up to 16 remote sites - i.e. running 16 simultanous tunnels to remote locations; either single teleworkers or remote networks/offices. The VPNs use induststry standard protocols including IPSec, PPTP and with high level encryption including 3DES, AES and MPPE. Cross compatibility with with common Microsoft Windows and MacOS VPN software clients is supported as well as compatibility with many other 3rd party VPN vendor's products, including Cisco™ Pix, Nokia™, Sonicwall™, Checkpoint™, ZyWall™ and Watchguard™. For more details on VPN, see DrayTek VPN.
| The Vigor 2800 includes full packet-level Stateful Packet Inspection, not just the inherrent NAT security and port-blocking of other routers. The router also employs keep-state packet recording; put simply, this means that when a packet is sent out, a reciprocal record is kept to allow a packet coming back in the opposite direction, but a default 'deny' policy means that any packet arriving which appears unsolicited won't get through. With SPI enabled, this is stricter and more secure than NAT alone, and also works for non-NAT routed connections. The Vigor2800 also features automatic protection from Dos/DDos (Denial of Service/Distributed Denial of Service) attacks and IP anti-spoofing. User-definable filters also allow you to add additional protection to your connection (see right). For added confidence, potential or foiled attacks are logged and can be reported via the router's syslog facility. | ![]() |
Wireless LAN Features (Vigor2800G/VG only)802.11g "Super-G" Performance
Wireless SecurityThe convenience of wireless LAN means that laptop users or those where running a cable is impractical can have access to your network and the internet, but security of Wireless LANs is vital; to this end, the Vigor2800G supports multiple independent levels of wireless security. The Vigor2800G supports industry standard WEP and WPA protocols for encrypting your wireless LAN traffic as well as the new WPA2 standard. You can lock the router down further so that only PCs whose unique hardware ('MAC') address is authorised can access the router. An 'at a glance' list can show you all wireless clients connected (see example below). "SSID Stealthing" makes your base more difficult to other people to scan for. For larger wireless LANs, the Vigor2800G also supports 802.1x Authentication to allow a permitted wireless user database on your Radius server. WDS - Wireless Distribution SystemWDS provides two modes of operation to expand the Wireless range of your LAN. Where you install two or more compatible wireless routers, the WDS-enabled router becomes a satellite (slave) to the main base. In 'Repeater' Mode, the slave unit is within range of the main base unit and then repeats the main wireless signal into its own coverage area - this can effectively double the total range of the network (depending on the environment). In WDS Bridge mode, two physically separated LAN can be joined wirelessly, in order than they can communicate with each other. This is ideal where two offices need to be linked but a cable cannot be run (e.g. across a road). Wireless VLAN & Rate ControlAs with the VLAN facility on the wired (RJ45) ethernet ports, the Wireless VLAN facility enables you to create groups of LAN clients which are common (can communicate with each other) or distinct (cannot communicate with each other) whilst still allowing Internet access to all clients. Wireless VLAN Groups can be combined with VLAN groups on the wired ports too. Wireless Rate Control allows you to limit the wireless rate that a particular wireless client can use.

Vigor 2800 VoIP Features ('V' Models only)The DrayTek Vigor2800V and 2800VG models provide two phone sockets, to provide Voice-Over-IP (VoIP) facilities. VoIP enables you to use your existing broadband capacity to carry regular voice calls to suitably equipped remote sites, for example another Vigor2800 VoIP-equipped router, to any other compatible VoIP device or, via a PSTN gateway to or from any other regular phone line or mobile phone worldwide. Using the Voice-over-IP facility is simple. You connect any standard telephone (corded or cordless) to one of the phone ports on the Vigor2800V. Although you can dial IP addresses, you would normally dial someone's 'SIP Address' which they obtain from their SIP Registrar (such as DrayTEL). You hear ringing and bust signals just like on a normal phone line. The voice calls (speech) are digitised and compressed in real time to make maximum use of the bandwidth and DrayTek's high performance 'codecs' provide 'toll quality' voice calls (quality similar to a regular fixed telephone line). A preset QoS system automatically gives voice traffic priority over other traffic without your available bandwidth.
The calls between the two sites above are free of charge, making use of your existing always-on ADSL connection, but cost isn't the only advantage; using VOIP means that you have additional call capacity in your home or office, without tying up your regular phone line. You can also make calls to regular phone lines, via a PSTN gateway such as DrayTEL (see later).
Multiple Simulataneous SIP RegistrationsFor the best VoIP integration, you set up accounts with SIP-compatible VoIP gateways, such as DrayTEL. You may have several VoIP accounts with your SIP provider (such as DrayTEL) or you may have accounts with various different SIP providers. The Vigor2800V allows you to set up up to 6 different accounts, and choose which of the two phone ports each of them rings (or either or both). You can also set your preferred SIP account for outgoing calls on each phone port:
Phone Directory - Quick DiallingRather than having to dial a whole IP or SIP address or phone number each time, the Vigor2800V has a quick-dial directory for up to 99 entries so that you can use a short code (of your choice). The router will automatically keep the SIP registrar updated with your current location (by IP address) so you do not need a fixed IP address.
Automatic QoS Assurance for VoIPTraffic levels from your local users to the Internet can vary; if someone else on your router is downloading, that will affect your speeds. Mostly that's quite tolerable - you just get your data a little slower but you wouldn't normally notice. With VoIP, things are different. A voice call has to be digitised, transmitted to the remote end and the turned back into an analogue waveform (sound!) in real-time. If part of a packet is delayed then the sound becomes jerky and intermittent which at best is annoying and in worst cases intolerable. The Vigor2800V firstly uses efficient codecs designed to make the best use of available bandwidth, but secondly includes automatic QoS Assurance. QoS (Quality of Service) Assurance reserves part of your Internet bandwidth for voice calls whilst a voice call is active (the reserved bandwidth is available for regular use if there is no Voice call active). This means that, regardless of what else other people are doing on your Network, you will always have the necessary inbound and outbound bandwidth reserved exclusively for Voice.

| The Vigor 2800 also helps protect against internal Internet abuse with its content filter which can block specified sites according to matched keywords which you specify - i.e. keywords within URLs (e.g. "hotmail"). You can alternatively set the router to only allow access to specific pre-set site - all other sites are blocked - i.e. you can select either a blacklist or a whitelist. Additionally, you can block Java/ActiveX applet downloads, cookies as well as HTML download of specific file types (e.g. ZIP, EXE, multimedia etc.). This all provides a deterrent to internal abuse of your Internet resources and re-inforce your local Internet user policies for staff or family members. | ![]() |
To protect your Internet connection from abuse or your users from unsuitable content, you can block popular Peer-to-Peer applications, as well as Instant Messaging software. You can set a time schedule so that the activities are allowed at only certain times of day. ![]() |

The Vigor 2800's VLAN facility enables you to segment each of the router's four Ethernet ports, so that each is a separate virtual LAN. You can create VLAN groups which include or exclude any of the ports so that groups, departments and companies can communicate with each other, or not. For example, two companies could share the same broadband feed, without having access to each other's networks. For more details of VLAN, see here.
Windows Syslog ToolThe Vigor2800 comes with its Syslog tool; one or more PCs can run this syslog tool so that route status and activity is continuously logged. This includes information about individual PC/User activity as well as firewall rule matching and general router operation. Syslog programs are available from 3rd parties for other Operating Systems too. The Vigor2800 also supports SNMP (with MIB-II), allowing an SNMP client to monitor the router's LAN activity, again locally or remotely. | ![]() Syslog Tool (Reduced) |
