Although it would seem that double-stack is still the preferred method of linux distribution, I want my next deployed in IPv6 only. For linux there is NAT-PT tomicki and NAT64 Viagenie. I don't have Cisco equipment although I'd like tested their NAT-PT, even if it's obsolete.
There are some lessons learned here with NAT-PT http://www.civil-tongue.net/6and4/wiki But, i would only use NAT-PT for ... no ... i would never use NAT-PT. The implementations are really not good.
Are some of you have installed one of these two implementations in production on recent versions of linux? Is it stable, secure, ... ?
I have tested 3 versions of DNS64 and 4 versions of NAT64. I am not sure what i can share about them. My experience has generally been good. I feel good with taking my selected vendors to production with this feature. Users in my beta trial have been happy with the results and performance. You mentioned Cisco. Cisco has stateless support today of NAT64, but i am not sure the value of that since it is one for one. I assume they will have stateful support soon. http://www.cisco.com/en/US/docs/ios/ios_xe/ipaddr/configuration/guide/iad_stateless_nat64_xe.html aka http://tinyurl.com/4gt9s9y Juniper has stateful NAT64 today in production code, i have not looked at this one yet, but it appears promising http://www.juniper.net/techpubs/en_US/junos10.4/information-products/topic-collections/nce/nat64-ipv6-ipv4-depletion/configuring-nat64-ipv6-ipv4-depletion.pdf aka http://tinyurl.com/4qxjahk If you are talking about servers, not users, most of the commercial load balancers have NAT64 functions for the IPv6 user to IPv4 legacy server use case.
