As mentioned, 6to4 doesn't do what you seem to think it does. Its not
a solution to the problem of IPv6 endpoints trying to talk to IPv4


Looks interesting. There's some version 0.4 user-space software for
Linux which claims to do it and Cisco claims to do it in IOS 12.4
advanced enterprise.

Let me know how it works out for you when you try it in "many to one"
mode. That is, many IPv6 addresses behind 1 IPv4 address, what Cisco
still insists on calling port address translation.
