AFAIK, IPv6 setup is much more difficult than IPv4 setup. Still i don't know well what IPv6 is. Let's go easy.. you need some practice with 6to4 setup. The 6to4 setup is very simple if you have the native IPv4 address(es). Then you can try the 6over4 (more difficult than 6to4) with gif(4). At first, here is good reference for 6to4 setup: http://www.onlamp.com/pub/a/onlamp/2001/06/01/ipv6_tutorial.html As fas as i can tell, you need practice and practice and practice, one by one, then you can obtain what you want..
