+.TP
+This creates a timeout policy for tcp using 100 seconds for the ESTABLISHED state, 10 seconds for CLOSE state and 10 seconds for the CLOSE_WAIT state.
+.TP
+Then, you can attach the timeout policy with the iptables CT target:
+.TP
+.B iptables -I PREROUTING -t raw -p tcp -j CT --timeout test-tcp
+.TP
+.B iptables -I OUTPUT -t raw -p tcp -j CT --timeout test-tcp
+.TP
+You can test that the timeout policy with:
+.TP
+.B conntrack -E -p tcp
+.TP
+It should display:
+.TP
+.B [UPDATE] tcp 6 100 ESTABLISHED src=192.168.39.100 dst=57.126.1.20 sport=56463 dport=80 src=57.126.1.20 dst=192.168.39.100 sport=80 dport=56463 [ASSURED]
