摘　　要：随着NGN、3G等IP网络业务的开展,向IPv6过渡的需求越来越迫切。隧道技术是过渡初期最易采用的方式,由于网络中大量NAT设备的存在,隧道技术中的NAT穿越问题是不容忽视的重点。该文通过对现有的普通隧道技术和Teredo隧道技术分析后,从NAT设备后IPv6孤岛接入IPv6网络的角度,提出了实现IPv6网络互联的IPv4UDP隧道实现方法,并详细说明在园区网和GPRS网络中的应用。With the explosion of the IP network service, such as NGN, 3G, transiting to the IPv6 network is on the agenda. Using tunnels is the most easily method to choose. However, NAT devices in the path will be a big tough thing in the transition to IPv6 network. This paper focuses on how to across the NAT device using IPv4 UDP tunnel after analyzing the normal tunnel mechanism and Teredo tunnel, then produces the application method of fixed network and GPRS network.
