please explain "--state RELATED/ESTABLISHED" rules in iptables
Fri, 21 Jun 2002 08:33:07 -0700
My firewall iptables script has rules
to drop lots of packets and only forward
I've seen lots of iptables scripts that
have rules with "--state RELATED"
and "--state ESTABLISHED".
I know these have to do with TCP packets
related to an existing TCP connection and such.
*What* are these rules good for? I didn't
use them and couldn't see a need for them.
