Ira secure connection is necessary then a virtual private network（VPN） is essential. IPSec use encrypting and encapsulating technology in client device and establishes a secure tunnel connection. The private network built by IPSec technology can ensure good transmission performance and service quality over public networks. This paper analyses the architecture of IPSec and describes the process of creating a site- to-site IPSec VPN between header and branch of enterprise over internet. In addition, this study analyses the encryption at the boundary of the network and concludes a propose some practical problems need to consider inside enterprise network.展开更多
