Default Problem with iptables connlimit patched kernel 2.6.23

Hello. We're having difficulty getting iptables to work with
connlimit.
We're running the latest kernel 2.6.23, and the connlimit modules
are compiled into the kernel.

when I try to add the rule,
iptables -v -A INPUT -p tcp --dport 80 -m connlimit --connlimit-above
16 -j DROP

I get the following back:
DROP tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 tcp dpt:80 #conn/
32 > 16
iptables: Invalid argument

It then puts the following message into /var/log/messages:
ip_tables: connlimit match: invalid size 32 != 16

Any help is appreciated.
Thank you

Check urine therapy on the internet ---- 143,000 web-pages.
Check "Erach A Irani", PhD and my work in artificial intelligence. I
am a PhD in Computer Science and a B.Tech from IIT Mumbai all india
rank 107 undergraduate Computer Science.

Please go to www.curezone.com ---- they need your help, 7000 members
online at any time.
Ask any doctor about urine therapy in any major hospital --- theyall
know about it.
See my diary and free help on Google Group "Lodha's Urine Therapy".
There is a beautiful woman called Nikki Cowan there who can give u
advice on Urine Therapy.
Thanks to massaging urine, drinking urine, going vegetarian/low-
protein, no usage of soap, and reducing medicines gradually under the
advice of the doctor my bipolar medicines have been reduced by my
doctor substantially by eliminating the rapid-cycling preventer
Tegretol, and substituting it with long acting injection Risperdal
Consta by Johnson and Johnson whose clinical trial is being done world-
wide.
