I have try to set up iptables on my computer with command line “iptables -t filter -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 1080 -j ACCEPT”, i know this command to set up on Red Hat Linux. So this command give a result “WARNING: The state match is obsolete. Use conntrack instead.
iptables: No chain/target/match by that name.”, how to find or set up chain/target/match.
