Hello I have these iptables rules which reject tcp connections with tcp rst.
/usr/sbin/iptables -A INPUT -p tcp --dport 143 -j REJECT --reject-with tcp-reset /usr/sbin/iptables -A INPUT -p tcp --dport 587 -j REJECT --reject-with tcp-reset When I telnet from another host to the protected port, it gets timeout message as follows. telnet: Unable to connect to remote host: Connection timed out IIRC, timeout should happen for iptables DROP action. Since I am using REJECT, why the connect shouldn't get disconnected quickly? Thank you. Tom
