Marc Blanchet iz podjetja Viagenie je na nekaj IPv6 mailing listah oznanil, da so obelodanili prvo odprtokodno implementacijo NAT64/DNS64 translacijskega mehanizma imenovano ECDSYS, ki naj bi prevajal med IPv6 in IPv4 protokolom…

Kolikor sem po hitrem branju razumel, ECDSYS deluje za promet iz IPv6 omrežja v IPv4, obratna funkcija pa ni omenjena (tudi ni logična, saj ne moremo mapirati 128bitnega naslovnega prostora v 32bitno). Do sedaj so vsi translacijski mehanizmi žalostno propadli, saj so se spopadali s precejšnjimi težavami. Morda tokrat ne bo tako, a nisem preveč optimističen. V naslednjih dneh bom mehanizem stestiral v go6labu in prve vtise boste izvedeli tu, na go6.

Izvorna koda, moduli in nekateri patchi so na voljo na strani ECDSYS.

Copy/paste Marcovega announce e-maila:

This is to announce the availability of two NAT64-DNS64 open-source
implementations by Viagenie, as follows:

======
NAT64
======
BSD PF:
this implementation of NAT64 is made by modifying the PF packet filter
available on BSD systems. A new ‘nat64’ statement is created in the
pf.conf file to enable the nat64 functionality.

Linux Netfilter:
The implementation of NAT64 for linux is available as a kernel module. It uses Netfilter’s facilities for packet interception. The
configuration is done with parameters provided at module insertion.

======
DNS64
======
As announced in july 2009 during IETF Stockholm, the companion DNS64
functionality is also available in two implementations, as follows:

BIND:
this implementation of DNS64 is made by modifying the BIND DNS server.
A new “dns64-prefix” statement in options is created in the named.conf
file to enable DNS64 functionality.

Unbound:
this implementation of DNS64 is made by adding a module to the Unbound
DNS server. To enable the DNS64 functionality, the module should be
declared and the dns64-prefix statement should be added in the
unbound.conf file.

The two functionalities (NAT64 and DNS64) make a complete system for
translating IPv6-IPv4 packets. The source code, some pre-compiled
packages and project description are available at:
http://ecdysis.viagenie.ca.

This project was funded by NLNet foundation
and Viagenie.

We are looking for feedback, patches, suggestions from the community.
