Ecdysis is aimed to develop an open-source implementation of a NAT64 gateway to run on open-source operating systems such as Linux and BSD. The gateway is comprised of two distinct modules: the DNS ALG and the IP translator. The DNS ALG is implemented in two DNS open-source server: Unbound and Bind. The IP translator is implemented in Linux as kernel module using Netfilter facilities and in openBSD as a modification of PF.

This project is funded by the NLnet Foundation and Viagénie.
