Could some kind soul please explain to me (or point me to information about) what the difference is between filtering on state ESTABLISHED in iptables and filtering on ! --syn? In other words, what's the difference between saying
iptables -A FORWARD -p tcp -m state --state ESTABLISHED -j ACCEPT and saying, iptables -A FORWARD -p tcp ! --syn -j ACCEPT My apologies if this has been discussed before - I am new to the list (and to iptables :) Thanks, Paul --------------------------------------------------------------------- Paul T.
