Ok, if I have good old ipv4 packet, or good new ipv6 packet they will go
through respective chains in respective tables (either for ipv4 or
ipv6). But how about ipv6-in-ipv4 packets? How is this handled when
packet is forwarded (especially by ipv6 enabled host)? How does the
packet traverse tables and chains once it reach destination and is
unwrapped from its ipv4 wrapper (does it go through both ipv4 and ipv6
tables and chains)? Any other special cases to watch for to prevent
packets that should be blocked to go through ipv6 back door?
