Iptables is a stateful firewall, so it maintains tables of all the sessions/connections made through it. The line above says that the firewall will allow traffic through the INPUT chain (or ruleset) that is already ESTABLISHED in the "state" table, or is RELATED to any sessions/connections already in the "state" table. jc -- Jeff Coppock Systems Engineer Diggin' Debian Admin and User
