The Vigor2910 series provides a configurable second WAN interface and supports policy-based load-balancing and connection fail-over on dual-WAN interface. Except the QoS function for the original IP layer, it also supports NAT session/bandwidth management which increases the usage efficiency of bandwidth greatly.
| Dual WAN Application |
| It allows users to access Internet and combine the bandwidth of the dual WAN to speed up the transmission through the network. Each WAN port can connect to different ISPs, Even if the ISPs use different technology to provide telecommunication service (such as DSL, Cable modem, etc.). If any connection problem occurred on one of the ISP connections, all the traffic will be guided and switched to the normal communication port for proper operation. |

What is VPN Backup?
If there is only one VPN tunnel between the main office and a remote branch office, when this VPN connection is dropped and can't be restored within minutes because of a network problem, you have to wait hours or days until the network administrator manually create another VPN connection. This will impact business operations and revenue.
With the DrayTek VPN Backup feature you can maintain a permanent connection between two sites. Once a VPN connection is dropped, an automatic backup VPN connection will be implemented.
Example :
A VPN TRUNK profile with member 1 (IPSec type) and Member 2(L2TP over IPSec) has been created for Router A for connecting with Router B. In general, Router A connects to Router B through Member 1 VPN tunnel (with IPSec type).
However, if the connection is off-line, Router A will use Member 2 VPN tunnel (with L2TP over IPSec) instead to connect Router B right away.

Subsidiary in Asia can use vigor router as VPN client. Every day it should transmit ERP, Mail or order information to headquarter in Europe. The Vigor router can build another backup VPN tunnel to subsidiary in America through LAN-to-LAN, and the VPN server in the subsidiary in American can build Routing /RIP. When the VPN tunnel is off-line, the subsidiary in Asia can send the data (that should be transmit to header quarter in Europe) to the subsidiary in America, then the subsidiary in America transmit the data to header quarter in Europe through VPN server by using VPN tunnel backup connection.

DrayTek supports 3G HSDPA USB Modem via USB port of Vigor2910 series from firmware version V3.0.6 and above. It is a good application for the mobile sharing environment.
For 3G mobile communication through Access Point is popular more and more, Vigor 2910 adds the function of 3G network connection for such purpose. By connecting 3G USB Modem to the USB port of Vigor2910, it can support HSDPA/UMTS/EDGE/GPRS/GSM and the future 3G standard (HSDPA, etc). Vigor2910 with 3G USB Modem allows you to receive 3G signals at any place such as your car or certain location holding outdoor activity and share the bandwidth for using by more people. Users can use four LAN ports on the router to access Internet.
