Subject: iptables limit-burst trouble
Date: Mon, 09 Jun 2003 11:22:21 +0900	[thread overview]
Message-ID: <20030609111735.C484.ACROYEAR@gmx.ch> (raw)


Hi,

I want to limit Web DoS attack.

I have set the following but it does not work well.

iptables -N flood-chk
iptables -A INPUT     -p tcp --dport 80 --syn -j flood-chk
iptables -A flood-chk -m limit --limit 1/sec --limit-burst 2 -j RETURN
iptables -A flood-chk -j LOG --log-prefix "IPTABLES HTTP FLOOD-PACKET"
iptables -A flood-chk -j DROP

After I accessed to my web site,
I pushed reload button of my web browser repeatedly but 
I was not denied by iptables.
Why?

regards,
