Hi list... I'm by now a little confused about QUEUE and NETLINK targets. Both are for queuing to userspace if I uderstand it correctly. But where is the diffrence between those two? Are they used for diffrent purpose or is just the userspace interface diffrent? Additionaly i've found two options in kernel .config file which are not documented under Documentation/Configure.help: CONFIG_IP_NF_NETLINK CONFIG_IP_NF_NETLINK_CONNTRACK What is theire purpose? Thanks for any answers. Greets Sebastian.
