The Vigor 2800 is DrayTek's flagship ADSL router - a combined ADSL router for Internet access, firewall, VPN device and Ethernet switch. 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. |

Vigor 2800 Enhanced Firewall
The Vigor2800 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.

ADSL Interface
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 regular ADSL as well as the newer ADSL2 and ADSL2+ standards, covering all ADSL lines available in the UK and all standard UK ADSL ISPs. The ADSL2/2+ compatibility means that you can take advantage of those new standards for their higher speed and greater reach/robustness.
ISDN Interface (Vigor 2800i/2800Gi)
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).
Selectable QoS Assurance
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.

Printer Port
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. |

High Performance VPN 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™.
