Overview

Vigor 2850 Series VDSL/ADSL Router Firewall 

The Vigor 2850 is a variant of our Vigor 2830 series with the addition of an extra VDSL interface (for the BT Infinity™ service) or other current VDSL services from other ISPs. This makes the Vigor 2850 ideal for users with ADSL now who might upgrade to VDSL later, but also for using VDSL as our primary feed and ADSL as your secondary or backup feed. Alternative WAN ports can instead provide connectivity to Ethenet feeds (for example a second ADSL modem) or a 3G cellular service using a USB adaptor. This latest router series includes support for professional features such as VLAN tagging, Gigabit Ethernet and dual-band switchable WiFi ('n' models).

Vigor 2850 connected to VDSL2 line

Packed with features, the Vigor 2850 offers truly comprehensive DSL connectivity and security. Compatible with all UK variants of ADSL (including ADSL2+ and Annex M) and VDSL (exc. Vectoring/G.INP/SIN498), the Vigor 2850 can also be used for cable-modem and leased line applications using an ethernet port (switchable with LAN port 4).

A four port Gigabit Ethernet switch on the LAN side provides high speed connectivity for your server, other local PCs or for uplink to a larger Ethernet switch. The 4th LAN port can instead operate as a WAN interface (for connection to an Ethernet-based Internet connection). Comprehensive security features include content filtering, web application controls and a new object based firewall management system.

 

Run ADSL and VDSL concurrently

The Vigor 2850 series has two DSL interfaces. One is ADSL the other is VDSL. If you have only ADSL right now, you can use that but know that you have a VDSL port available to allow for upgrading when VDSL service is available to you. You can also just use the VDSL port on its own if you have VDSL service. If you have both services, you can connect the router to both line, and set them up in load balancing mode, where traffic is split across both of them, or into failover mode, where the ADSL line only kicks-in if your VDSL line fails (or vice versa). ADSL makes a particularly good method of failover for VDSL because they are delivered differently. VDSL service is provided and powered by a cabinet in your street - that's where the line terminates. ADSL service, on the other hand, comes all the way from your local exchange, which coul be miles away and is powered from there. That means that if your street's VDSL cabinet is damaged, its DSLAM fails or you lose power to your street, you lose VDSL, but your ADSL line comes via a different method and route, so it's less likely that both would be affected. These failover methods can also be used instead for the other WAN ports on the router (Ethernet or 3G). If you need two ADSL lines, you can add a Vigor120 ADSL modem for the second line.

Robust & Comprehensive Firewall

Security is always taken seriously with DrayTek routers. The firewall protects 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. The latest ('Version 3') DrayTek object-based firewall allows even more setup flexibility than ever, enabling you to create combinations of users, rules and restrictions to suit multi-departmental organisations. The Vigor 2850 now also allows selective direction firewall rules of LAN to WAN, WAN to LAN or LAN to VPN. In addition, QoS (Quality of Service Assurance) can now be selectively applied to specific users.

IPv6 - Next Generation Internet Routing

The Vigor 2850 supports IPv6 - the successor to the current IPv4 addressing system that has been used since the Internet was first created. IPv4 address space is full up and IPv6 allows for much more efficient routing and a larger address space. IPv6 is supported both from your own ISP, but if your ISP does not (yet) support IPv6, the Vigor 2850 also supports IPv6 broker/tunnel services to provide IPv6 accss using either TSPC or AICCU via 3rd party IPv6 providers. To learn all about IPv6, you can get our detailed guide to IPv6 here.

IPv6 on the Vigor 2850 provides the following features:

  • Operation on any one of the WAN ports (ADSL, VDSL, Ethernet or 3G)
  • Connectivity to direct native IPv6 ISPs
  • Built-in tunneling to 3rd party IPv6 brokers
    suppporting TSPC or AICCU methods
  • Default stateful firewall for all IPv6 LAN Clients/Devices
  • DHCPv6 Client or Static IPv6 Client
  • DHCPv6 & RADVD for client configuration
  • IP Filtering Rules
  • QoS for IPv6 with DiffServ
  • Router Management over IPv6 (Telnet/HTTP) with IPv6 Access List
  • Simultaneous (concurrent) operation with IPv4 ("Dual-Stack")
  • Other router features are available on IPv4 only currently

Web Content Filtering

The content control features of the Vigor 2850 allow you to set restrictions on web site access, blocking download of certain file or data types, blocking specific web sites with whitelists or blacklists, blocking IM/P2P applications or other potentially harmful or wasteful content. Restrictions can be per user, per PC or universal. Using DrayTek's GlobalView service, you can block whole categories of web sites (e.g. gambling, adult sites etc.), subject to an annual subscription to the Globalview service, which is continuously updated with new or changed site categorisations or sites which have become compromised (such as infected with Malware). A free 30-day trial is included with your new router.

 

Quad-WAN Load Balancing & Backup

GlobalView Categories

The Vigor 2850 features four methods of WAN connectivity - ADSL, VDSL, Ethernet (Gigabit, switchable with LAN4) and a USB port for connection of a 3G modem. The ethernet port can connect to a second ADSL modem (e.g. Vigor 120), a cable modem or any other Ethernet-based Internet feed. The multiple WAN interfaces can be used either for WAN-Backup or load balancing. Load-balancing or failover supports IPv4 only currently.

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 VDSL or 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 Internet connectivity (main, backup or load balanced) by connecting to a compatible USB modem (or cellphone) for access to the high speed 3G cellular networks from UK providers such as Vodafone, T-Mobile, 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.
