基于Linux的自动网关的设计与实现

Design and Implementation of NetPnP Based on Linux

通过对ARP协议的分析,及Linux操作系统中的iptables防火墙策略的深入研究,探讨了利用iptables的NAT规则解决模拟网关的问题,实现了局域网环境下即插即用的自动网关。

This paper analyses the ARP protocol, studies the firwall policy of the iptables in Linux operating system, discusses how to use iptables rules to carried out a simulation gateway based on NAT, and realities a NetPnP gateway on LAN.
