摘　　要：当前大多校园网都是通过国家教育网接入的,但通过教育网访问公网速度较慢,不能满足用户的需要。针对此问题提出以Linux为平台用网络双出口解决问题,即当访问教育网时从教育网出口,访问公网时通过当地ISP出口。详细介绍了在Linux下策略路由、NAT技术的原理和具体实现,以及如何将这两个技术相结合实现网络双出口,为需要解决此类问题的用户提供一个切实可行的解决方法。At present most campus nets are joined with the national education network, which can＇t satisfy the user＇s need be cans the speed to access the public is slower. In view of this question the problem is solved via the network dual-export on Linux platform, namely when accessing the education network via the education network export, and accessing the public net via the local ISP export. The policy routing, the NAT technology principle and the concrete realization on Linux are introduced in detail. The method of unifies these two technologies to realize network dual-export is given, which provides a practical feasible solution to the users who need to solve this kind of the question.
