Connection state matching (CONFIG_NETFILTER_XT_MATCH_STATE)

Allows you to match packets based on their relationship to a tracked connection (ie. previous packets). For example for a desktop firewall.

Code: Select all

iptables -F
iptables -t filter -A INPUT -j DROP
iptables -t filter -I INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
Basically, all network connections are blocked from the outside except our system has established the connections.
