I installed ipp2p into my system (CentOS 4 kernel 2.6.9-11.EL iptables 1.2.11 ). IPP2P's doc recommend use "-j CONNMARK" to mark a conntrack that it begin with a ipp2p packet. But when I enter "iptables -t mangle -A PREROUTING -m mark --mark 2 -j CONNMARK --save-mark" into my system , it show me message : "iptables: No chain/target/match by that name" . When I enter "ls /lib/modules/2.6.9-11.EL/kernel/net/ipv4/netfilter/" , it have not ipt_connmark.ko(or ipt_CONNMARK.ko).
