These patches are for natting IPv6 addresses behind whole IPv6 subnets
or just behind one IPv6 address.

This is useful for multiple Internet uplinks, where you want full control
on the router what connections are sent over which interface. Or its quite
easy to setup Load Balancing rules or create a DMZ. There a lots of use
casesŠ

If you are looking for IPv4->IPv6 or IPv6->IPv4, there are multiple
implementations. Two examples:

IPv6->IPv4:

IPv4->IPv6:
