Abstract
With the development of the Internet and IPv6,there appears coexistence of network based on the IPv4 and IPv6.This paper introduces some key technologies about the evolvement from IPv4 to IPv6 and compares the differences between them.The paper presents the kernel working process to translate gateway about the communication between pure IPv4 nodes and pure IPv6 nodes during transition from IPv4 to IPv6.A modularized design of the translation gateway based on NAT-PT is brought forward with the application of the netfilter function framework.
