7.7 VPN Hub functions

Many enterprises build a VPN to build VoIP to achieve better call quality. However, after the establishment, only the VoIP contacts between the external and the central points can be established, and the communication between the external and external points cannot be established. This is because IPSec VPN is point-to-point communication and does not allow external nodes to communicate with each other. Therefore, star VPN networks cannot communicate with each other. The VPN Hub function is used to connect external sites through the central point of the headquarters. This greatly increases the convenience of data sharing and decentralized management.
After the sub-points are connected to the headquarters, the sub-points can be interconnected, without having to establish a channel between the devices of each sub-point for convenient management and resource saving. Different carriers of China Telecom and China Netcom lines can be switched through the central point of the Headquarters, so that the online speed is not delayed and the problem of cross-Network VPN connection is very difficult. At the same time, it can also combine the bandwidth management function of xiaonuo's expertise to allow the Headquarters administrator to control the interconnection between different support points to achieve more strict control.
