mhh looks for me wrong. What happens if the source will connect with
more than one connectionat the same time to the same target and port:
IPv6 client:port Public v4:port Dest v4:port
[2001:db8::1]:60000 -> 192.0.2.1:54321 -> ebay.co.uk:443
[2001:db8::1]:50000 -> 192.0.2.1:54321 -> ebay.co.uk:443
[2001:db8::1]:40000 -> 192.0.2.1:54321 -> amazon.com:443
[2001:db8::a]:40000 -> 192.0.2.1:43210 -> amazon.com:443
[2001:db8::a]:30000 -> 192.0.2.1:43210 -> amazon.com:443
[.................] -> 192.0.2.1:54321 -> [............]
>From my point of view this will break connections.
