LAN-to-LAN VPN Services
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 Vigor2910 can act as a VPN concentrator (endpoint) for up
to 32 remote sites - i.e. running 16 simultaneous 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. No additional licences are needed for users. 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™, Juniper™ and Watchguard™. For more details on VPN, see DrayTek VPN

Vigor2910 Enhanced Firewall
The Vigor2910 includes full packet-level
firewall facilities and also employs stateful
packet inspection/recording for both NAT and
non-NAT (IP routed) modes. A default 'deny'
policy means that any packet arriving which
appears unsolicited won't get through to your
LAN. The Vigor2910 series also features
automatic selectable 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); a new object-oriented
system makes specifying flexible filter sets
easier and more flexible. For added
confidence, potential or foiled attacks are
logged and can be reported via the router's
syslog facility or emailed to you by the
router.
Voice-Over-IP (VoIP) Features
The Vigor2910VG model adds twin phone ports for VoIP (Voice over IP). VoIP enables you to use your
existing broadband capacity to carry regular voice calls to suitably equipped remote sites, for example
another Vigor VoIP enabled router or to other compatible hardware/software products. The DrayTek supports
the open 'SIP' standard for compatibility with other vendors' produdcts.
The calls between the two sites in the example above are, of course, free of charge because they are 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. Using a
VoIP-PSTN gateway service, such as DrayTEL
you can also fully integrate with the PSTN, making and
receiving calls to and from any regular phone number, worldwide.
