摘　　要：目前很多用户的局域网通过一个出口接入Internet但速度较慢。针对这一问题,提出以Linux为平台用双出口解决问题。介绍了在Linux下的NAT、策略路由技术的原理与具体实现方案,并介绍了通过iptables工具将这2种技术相结合的方法,提出的方案通过shell脚本使Linux能自动完成,为用户解决此类问题提出了一个切实可行的方法。At present most LAN joined with Internet from one export, but the speed access to Internet is slow. In view of this question the problem is solved via the LAN dual- export in Linux platform. The NAT, the policy routing technology principle and the concrete realization on Linux are introduced in detail, and the method of unified these two technologies with iptables is given, the solution in this paper can achieve by Linux shell scripts, which provides a practical feasible solution to users who need to solve this kind of the question.
