Abstract

Internet protocol version 6 (IPv6)-to-IPv6 network address translation (NAT66) is a new technology, which is proposed to provide the address independence benefit associated with IPv4-to-IPv4 NAT (NAT44) while minimizing the problems. Some corporate network managers may deploy NAT66 in their internal IPv6 network to hide their topology, to utilize multi-homing and so on. This paper introduces the checksum-neutral two-way network address mapping algorithm used in ANT66 to solve the problem of network translation from an IPv6 address to another in global systems engineering (GSE) mode and implements it both in a Linux host and a customer-provided equipment (CPE) router with netfilter/iptables. Meanwhile, this paper gives the experimental results in IPv6 network to show the performance.
