摘　　要：企业员工出差在外时,经常需要通过公共网络连接回公司网络进行工作,这种情况下就需要保障数据在公共网络上传递的安全性。L2TP VPN通过为远程用户分配企业内部IP地址,并对数据报文进行封装,使其在逻辑上依然处于企业内部网络之中,从而为其通过公网与企业内部网络之间的通信提供安全保护。When employees travel,they often need to connect to the company network through the public network to work.In this case,they need to ensure the security of data transmission on the public network.L2TP VPN provides security protection for com?munication between public and internal networks by assigning internal IP addresses to remote users and encapsulating data pack?ets so that they are logically still in the internal network of the enterprise.
