HI, I still have this issue, I checked the kernel build, and everything under ipv6 except ipv6nat is enabled, yet the CT target fails. This same rule on ipv4 works iptables 1.4.20 on kernel 3.10.10 ip6tables -v -A PREROUTING -t raw -m multiport -p tcp --dports 6667,8888,16667 -j CT --helper irc CT tcp opt in * out * ::/0 -> ::/0 multiport dports 6667,8888,16667 CT helper irc ip6tables: No chain/target/match by that name. incase it was multi upsetting it, also tried ip6tables -v -A PREROUTING -t raw -p tcp --dport 6667 -j CT --helper irc CT tcp opt in * out * ::/0 -> ::/0 tcp dpt:6667 CT helper irc ip6tables: No chain/target/match by that name. any suggestions? -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
