[tproxy] error comming --ip_tables: TPROXY target: invalid size 8 != 16

[Tanvir Adnan]

hello everyone

i am trying to configure my tproxy,

i am using debian - kernel 2.6.18.6 and  successfully patched the 
cttproxy-2.6.18-2.0.6.
and iptables-1.4.3.1 successfully patched by 
tproxy-iptables-1.4.0-20080521-113954-1211362794.patch
now i am going to add the following chain on my iptables--

 iptables -t tproxy -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j 
TPROXY --on-port 80

it is showing this following error---

iptables: Invalid argument. Run `dmesg' for more information.

debproxy:~# dmesg
ip_tables: TPROXY target: invalid size 8 != 16
ip_tables: TPROXY target: invalid size 8 != 16


Please let me know where is the problem and how to  solve this.

thanks and regards

Adnan
