Hi again,

in order to clear things up, let me summarise this bug from my point of view:
 * IPv6 SNAT for a range of IP addresses works
 * IPv6 SNAT does not work for a range of IP addresses with --random, answer
   packets are not translated back to the original source IP

Desired behavior: Answer packets to packets which did undergo SNAT should be
translated back to the original source IP even when --random is used.

Observed behaviour: Answer packets to packets which did undergo SNAT are not
translated back, instead an ICMP packet is sent that the translated IP address
is unreachable.

Maybe this summary clears things up. I'm really interested in solving this bug,
so please contact me when you have an idea on how to debug it...

Best regards,
Alex
