摘　　要：IPSec VPN和防火墙为网络的安全做出了重大贡献。采用IPSec VPN技术不仅可实现数据在公网中安全传输,还可在一定程度上保护内网安全;防火墙所完成的任务是保护网络不受非法的"入侵"。当IPSec VPN与防火墙同时共存于同一系统中时需考虑两者的协同工作问题。文中提出了并实现了一种基于虚拟网卡技术的IPSec VPN系统。将虚拟网卡与IPSec VPN相结合的系统可有效实现IPSec VPN与内网防火墙协同工作。IPSec VPN and firewall make great contributions to the safety of network. IPSec VPN technology can both safely transmit data in public network, and to a certain extent, protect the safety of internal network. Firewall can protect network form being illeagally intruded. The coexistence of IPSec VPNand firewall in a system needs consideration of the cooperative working between the two. In this article, a IPSee VPN system based on virtual adapter is suggested and implemented. This system, combining IPSec VPN and virtual adapter, can effectively realize the cooperative work of IPSee VPN and firewall for internal network.
