+     The user-space helper infrastructure requires a Linux kernel &gt;= 3.6
+     to work appropriately.
+    </para>
+   </note>
+
+<para>Connection tracking helpers allows you to filter multi-flow protocols
+that usually separate control and data traffic into different flows.
+These protocols usually violate network layering by including layer 3/4
+details, eg. IP address and TCP/UDP ports, in their application protocol
+(which resides in layer 7). This is problematic for gateways since they
+operate at packet-level, ie. layers 3/4, and therefore they miss this
+important information to filter these protocols appropriately.</para>
+
+<para>Helpers inspect packet content (at layer 7) and create the so-called
+expectations. These expectations are added to one internal table
+that resides in the gateway. For each new packet arriving to the
+gateway, the gateway first looks up for matching expectations. If
+there is any, then this flow is accepted since it's been expected.
+Note this lookup only occurs for the first packet that is part of one
+newly established flow, not for all packets.</para>
+
+<para>Since 1.4.0, conntrackd provides the infrastructure to develop
+helpers in user-space. The main features of the user-space infrastructure
+for helpers are:</para>
+
+<itemizedlist>
+
+<listitem><para>Rapid connection tracking helper development, as developing code
+in user-space is usually faster.</para></listitem>
+
+<listitem><para>Reliability: A buggy helper does not crash the kernel. If the helper
+fails, ie. the conntrackd crashes, Moreover, we can monitor the helper process
+and restart it in case of problems.</para></listitem>
+
+<listitem><para>Security: Avoid complex string matching and mangling in
+kernel-space running in privileged mode. Going further, we can even think
+about running user-space helper as a non-root process.</para></listitem>
+
+<listitem><para>It allows the development of very specific helpers for
+proprietary protocols that are not standard. This is the case of the SQL*net
+helper. Implementing this in kernel-space may be problematic, since
+this may not be accepted for ainline inclusion in the Linux kernel.
+As an alternative, we can still distribute this support as separate
+patches. However, my personal experience is that, given that the
+kernel API/ABI is not stable, changes in the interface lead to the
+breakage of the patch. This highly increase the overhead in the
+maintainance.</para></listitem>
+
+</itemizedlist>
+
+<para>Currently, the infrastructure supports the following user-space helpers:

+
+<orderedlist>
+<listitem><para>Register user-space helper:
+
+<programlisting>
+nfct helper add rpc inet udp
+nfct helper add rpc inet tcp
+</programlisting>

+This registers the portmapper helper for both UDP and TCP (NFSv3 traffic goes both over TCP and UDP).
+</para></listitem>

+<programlisting>
+# iptables -I OUTPUT -t raw -p udp --dport 111 -j CT --helper rpc
+# iptables -I OUTPUT -t raw -p tcp --dport 111 -j CT --helper rpc
+</programlisting>
+
+With this, packets matching port TCP/UDP/111 are passed to user-space for
+inspection. If there is no instance of conntrackd configured to support
+user-space helpers, no inspection happens and packets are not sent to
+user-space.</para></listitem>

+Helper {

+		QueueLen 10240
+                Policy rpc {
+                        ExpectMax 1
+                        ExpectTimeout 300

+                }
+        }
+}
+</programlisting>
+
+This configures conntrackd to use NFQUEUE queue numbers 1 and 2 to send traffic
+for inspection to user-space</para>
