Likely, I'm using the "limit" option to stop sucking up my logfiles:
$IPTABLES -A invalid -m limit -j LOG --log-prefix "invalid "
$IPTABLES -A xmas -m limit -j LOG --log-level info --log-prefix "xmas-scan "
$IPTABLES -A null_scan -m limit -j LOG --log-level info --log-prefix \
"null-scan "
$IPTABLES -A CHECK_FLAGS -p tcp --tcp-flags SYN,RST SYN,RST \
-m limit --limit 5/minute \
-j LOG --log-level 6 --log-prefix "SYN/RST "
$IPTABLES -A spoofing -m limit -j LOG --log-level info --log-prefix "spoofing "
$IPTABLES -A INPUT -i $DEV_INET -p icmp --icmp-type 5 -m limit -j icmp_reject
$IPTABLES -A icmp_reject -m limit -j LOG --log-prefix "icmp_rej "
$IPTABLES -A INPUT -m limit -j LOG --log-prefix "Denyed FINAL IN "
$IPTABLES -A OUTPUT -m limit -j LOG --log-prefix "Denyed FINAL OUT "
$IPTABLES -A FORWARD -m limit -j LOG --log-prefix "Denyed FINAL FOR "
The default policy is drop, for all chains.
