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. Figure 3 . VPN Backup Application 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 headerquarter in Europe) to the subsidiary in America, then the subsidiary in America transmit the data to headerquarter in Europe through VPN server by using VPN tunnel backup connection.

Note: PSTN-PBX is widely adopted by most Annex A countries. Because most Annex B countries such as Germany, Norway, the Netherlands have encouraged small offices to deploy ISDN PRI into PBX, PRI PBX are quite popular at offices located in Germany, the Netherlands, Norway.

1) Sunny presses prefix number (e.g."7") firstly to choose exterior line - FXS of Vigor2910V (A).

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.

Operating : 0簞C ~ 45簞C

2) After connection success, presses Sunny's extension 610.
