Who needs all this crazy firewall stuff when I have my

iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -i ppp0 -j DROP

And for IPv6 you don't need a firewall, just use slaac and hope no one finds the address /s
