摘要
IPv6的新特点和应用对现有的安全设备结构提出了挑战。同时,从IPv4升级到IPv6是一个长期的过程,两种协议在一定时间内将共同存在。因此,需要设计支持IPv4/IPv6双协议的防火墙以适应过渡时期的需要。本文分析了IPv4到IPv6的过渡策略,并设计与实现了支持IPv6/IPv4协议的防火墙系统。
The new characteristic and the application of IPv6 （Internet Protocol Version 6） proposed the challenge to the existing safety equipment structure. At the same time, upgrading from IPv4 to IPv6 is a long-term process, and two kinds of protocol will coexist in a certain period of time. Therefore, the firewall that supports the IPv4/IPv6 double protocol needs to be designed to sat- isfy the transition period. This article analyzes the transition strategy from IPv4 to IPv6, also designs and realizes the firewall system supporting the IPv6/IPv4 protocal.
