Having a rule doesn't mean that it's doing what you want it to.  =)
Since you have DROP policies, having EST/REL packets return to the
originating INPUT/FORWARD chain just drops them if nothing else
matches.  Instead, try ACCEPT, as in:

iptables -A attacksinput -m state --state ESTABLISHED,RELATED -j ACCEPT

Can I get confirmation from Jan or someone else that a preferred and
more future-proof syntax is the following?

iptables -A attacksinput -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT

--Mike
