You're so fucking dense and incredibly close minded, and by all means, a complete idiot.
A stateful firewall is a RULE. A fucking CONFIGURATION LINE in a text file. The syntax for IPv6 stateful firewall IS EXACTLY THE SAME in Linux for IPv4 and IPv6.
This is the IPv4 configuration for NAT:
iptables -t nat -A PREROUTING -o interfaceN -j MASQUERADE
iptables -A FORWARD -i interfaceN -m state --state established -j ACCEPT
iptables -P FORWARD DROP
This is what you do for similar effect in IPv6:
ip6tables -A FORWARD -o interfaceN -j ACCEPT ------ NO NAT, JUST LET EVERYTHING OUT!
ip6tables -A FORWARD -i interfaceN -m state --state established -j ACCEPT
ip5tables -P FORWARD DROP
See the difference?
