Hi,

I am having problems adding a stateful inspection rule with ip6tables on CentOS4.5.

#ip6tables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

That's what I am trying to do, but

#ip6tables: No chain/target/match by that name.

I have been googling but unable to solve the problem. any ideas?

maybe You need to specify protocol with -p tcp ?
