The transition from IPv4 to IPv6 is doomed to be a long process.The network Address translation(NAT) technology is used very popularly 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 through 6to4 tunnel.The scenario is implemented and the gateway system’s performance is analyzed.
