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. 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. 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.
