I do not understand what you mean, can you please correct my iptables lines to know where is the mistake.

Thanks

Hello

I want to save the log of iptables and for this I have set up the file
/etc/rsyslog.d/iptables.log :

:msg, contains, "" -/var/log/iptables.log
& ~

Packets arrive correctly because I can connect to the servers, but does not
save the log of these lines :

$IPTABLES -t nat -A PREROUTING -p TCP -i $INTERNET_IFACE -d $INTERNET_IP
--dport 8181 -j DNAT --to-destination 192.168.2.26
$IPTABLES -A FORWARD -p TCP -i $INTERNET_IFACE -o $LAN_IFACE -d 192.168.2.26
--dport 8181 -j LOG --log-prefix "Port 8181:"
$IPTABLES -A FORWARD -p TCP -i $INTERNET_IFACE -o $LAN_IFACE -d 192.168.2.26
--dport 8181 -j allowed
$IPTABLES -A FORWARD -p TCP --sport 8181 -s 192.168.2.26 -i $LAN_IFACE -o
$INTERNET_IFACE -j ACCEPT

But these lines if you save:

$IPTABLES -A FORWARD -m limit --limit 3/minute --limit-burst 3 -j LOG
--log-level DEBUG --log-prefix "forward packet died:"

Use:

CentOS 6.3 64 Bits
iptables 1.4.7
rsyslogd 5.8.10

Please could help correct my problem?

Thank you,

    AFAIK, if you want to log a given rule, you either double that
rule and instead of -j ACCEPT you put the -j LOG stuff or group the
rules you want to log together, you have to put them into your own
chain and tell it to log the entire chain.

Or something like that
