Servers usually use IP addresses of the data center. In order to realize some special functions, sometimes it’s necessary that the server uses IP address of remote data center. But the internet architecture makes it difficult to achieve. To build a tunnel on the internet using VPN technology, the server and the remote data center will be directly connected in the network layer. Then through the configuration of the routing rules, the server using the IP address of remote data center can be realized. Some characteristics in application will also be presented.
