[tproxy] Issue with iptables for tproxy

Hi I am trying to build tproxy support for haproxy on Ubuntu 10.04 LTS 64 bit server. The kernel has the tproxy support .config | grep -E '(NF_CONNTRACK=|TPROXY|XT_MATCH_SOCKET|XT_TARGET_TPROXY)' CONFIG_NF_CONNTRACK=m CONFIG_NETFILTER_TPROXY=m CONFIG_NETFILTER_XT_TARGET_TPROXY=m CONFIG_NETFILTER_XT_MATCH_SOCKET=m and the iptables version is 1.4.4 Now when I execute the iptables rule iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT iptables: No chain/target/match by that name. I get this issue. Any thought or advice will be highly appreciated. regards
