Ah, in that case i misunderstood this type of 6to4 tunnel. I have a 
fixed ipv6 subnet. I forward and DNAT all sit traffic from the NAT 
device to the tunnel endpoint.

So this will not be universally usable, you need cooperation of your 
DNAT device. Your original statement stands as it is, as my situation is 
probably not something NM has to handle at all.
