This question may be sound trivial, of course when dealing with IPv6 addresses ip6tables is appropriate. But if I have machine with dual IPv4/IPv6 stack , does it mean that netfilter have separate set of tables/chains for IPv4 and IPv6 so I need to have 2 set of commands to protect for example from syn flooding ? Or in another terms which of iptable command are IPv4/v6 neutral?
