LinuxQuestions.org - iptables - connlimit doesnt work

Hi all,

I would like to limit incomming connections in my firewall. My second server has a kernel:

2.6.18-028

The problem is when I`m trying to use "connlimit" in iptables.

I`m pretty sure that this rule is OK:

Code:

iptables -A INPUT -p tcp --syn --dport 80 -m connlimit --connlimit-above 20 -j REJECT --reject-with tcp-reset

but for some reason when I`m trying to execute this I see this:

Code:

iptables: No chain/target/match by that name

Connlimit module is in the folder

Code:

/lib/xtables/libxt_connlimit.so

Maybe its not loaded ? I have no idea how to install connlimit for iptables... who can help me ?
