摘　　要：IPv6协议已经逐步走向成熟,但IPv4向IPv6的过渡注定是一个漫长的过程,现有IPv4网络中广泛使用NAT(network address translation)技术来缓解地址短缺的问题。为了使NAT域内的用户能够接入IPv6网络,成为过渡阶段亟待解决的问题。在研究IPv4向IPv6过渡技术的的基础上,将IPv4下的NAT技术应用到IPv6网络中,提出了利用6to4隧道穿越NAT的网关系统方案,并对系统进行了具体的实现和性能分析。Although IPv6 protocols are reaching maturing, the transition from IPv4 to IPv6 is doomed to be a long process. The NAT technology is used very propularly in IPv4 network to make up the shortage of network address. It is a desiderated problem to make the users behind NAT gateway to access to IPv6 networks. By studying the transition technology from IPv4 to IPv6 and introducing NAT technology in IPv6, a scenario is put forward througth 6to4 tunnel. The scenario is implemented and the gateway system＇s performance is analysed.
