Hello all, You would be great if you could help me on this: I'm using these 3 rules: 1. iptables -P INPUT DROP 2. iptables -A INPUT -m state --state ESTABLISHED -j ACCEPT 3. iptables -A INPUT -p tcp --dport 23 -m state NEW,ESTABLISHED -j ACCEPT Then 4. Bob connects on my telnet... 5. I decide to suppress rule 3: iptables -DINPUT -p tcp --dport 23 -m state NEW,ESTABLISHED -j ACCEPT 6. Packets from Bob are still accepted because of rule 2. But I need this rule (2) for my out-going connections responses. Is there a way to suppress the state which has been recorded for rule 3, when deleting this rule? Thanks in advance for your help, Yoann
