For HQ/Main office :
With four WAN/DMZ ports which can be configured as either an Internet-facing WAN interface or as a LAN-facing physical DMZ, the combination of WAN interface ports can let you use multiple Internet connections to provide greater total bandwidth capacity or fault-tolerance.
For remote sites :
Employees in remote sites would need to have VPN connection with their HQ to execute their daily job. Most single teleworkers can use the VPN capabilities embedded inside iPhone/PC/notebook. The branch offices/small offices can make use of other Vigor routers (or other brand VPN) for the VPN termination.
