I want to accept connections that are already established. I tried this command:
# iptables -I INPUT 1 -m state --state ESTABLISHED,RELATED -j ACCEPT
But then it throws this error at me:
iptables: No chain/target/match by that name
Without "-m state --state etc..." the command works fine, so I have narrowed it down to the state module. But:
# iptables -m state -h
Correctly produces the help for the state module, so I do
have it. What's the problem?
