Instead of trying to "fix" 6to4, which also has this rather annoying

Teredo
forward which has all these points resolved already?
The Teredo model, actually from our observation with available code
from its
major source, is that both end need to have it configured to enable a
reliable connection.
We tried with an open Teredo relay, and packets went sometimes to
Korea,
sometimes nowhere.
In other words, this is fine to get IPv6 working between 2 PCs in
different
homes separated by NAT boxes, but this is not usable to access a
regular
IPv6 server on the Internet **UNLESS** that server also deploys
Teredo...
So, going that route, if an IPv6 server wants to offer reliable
service to
customers, it might have to be configured with:
- a regular global IPv6 address to serve regular IPv6 native customers
- a 6to4 address to serve 6to4 customers and avoid open relays
- a Teredo address to serve PC behind NAT box that uses Teredo
IMHO, this makes the deployment model of new servers a bit complex...
