This looks interesting. Thanks for submitting it. The first (that I know of) NAT64 implementation was in OpenBSD 5.1 release and there's support in the default firewall/packet filter (pf). I think FreeBSD has this code working as well, but I'm not sure, and I'm too lazy to check. Here are some OpenBSD 5.1 release NAT64 details: http://www.h-online.com/open/news/item/NAT64-OpenBSD-5-1-will-translate-between-IPv6-and-IPv4-1443416.html http://www.h-online.com/open/news/item/NAT64-OpenBSD-5-1-wil... The following talk on NAT64 is a bit old (2010) but good http://www.bsdcan.org/2010/schedule/events/197.en.html http://www.bsdcan.org/2010/schedule/events/197.en.html

I find it ironic that the h-online was 'corrected' following a reader's comment ("IPv4 host can not initiate a connection with a IPv6 only host with NAT64"). This is actually false. The NAT64 gateway _can_ do this, provided you have configured it correctly. I found this http://home.nuug.no/~peter/pf/eurobsdcon2012/nat64.html http://home.nuug.no/~peter/pf/eurobsdcon2012/nat64.html quite helpful, as well as a post on the mailing list [1] describing commong scenarios. Of course, the pf.conf manpage describes with all the details, but that should go without saying :-) [1] http://www.mail-archive.com/misc@openbsd.org/msg107255.html http://www.mail-archive.com/misc@openbsd.org/msg107255.html
