+	# Netlink event socket buffer size. If you do not specify this clause,
+	# the default buffer size value in /proc/net/core/rmem_default is
+	# used. This default value is usually around 100 Kbytes which is
+	# fairly small for busy firewalls. This leads to event message dropping
+	# and high CPU consumption. This example configuration file sets the
+	# size to 2 MBytes to avoid this sort of problems.
+	#
+	NetlinkBufferSize 2097152
+
+	#
+	# The daemon doubles the size of the netlink event socket buffer size
+	# if it detects netlink event message dropping. This clause sets the
+	# maximum buffer size growth that can be reached. This example file
+	# sets the size to 8 MBytes.
+	#
+	NetlinkBufferSizeMaxGrowth 8388608
+
+	#
+	# If the daemon detects that Netlink is dropping state-change events,
+	# it automatically schedules a resynchronization against the Kernel
+	# after 30 seconds (default value). Resynchronizations are expensive
+	# in terms of CPU consumption since the daemon has to get the full
+	# kernel state-table and purge state-entries that do not exist anymore.
+	# Be careful of setting a very small value here. You have the following
+	# choices: On (enabled, use default 30 seconds value), Off (disabled)
+	# or Value (in seconds, to set a specific amount of time). If not
+	# specified, the daemon assumes that this option is enabled.
+	#
+	# NetlinkOverrunResync On
+
+	#
+	# If you want reliable event reporting over Netlink, set on this
+	# option. If you set on this clause, it is a good idea to set off
+	# NetlinkOverrunResync. This option is off by default and you need
+	# a Linux kernel >= 2.6.31.
+	#
+	# NetlinkEventsReliable Off
+
+	# 
+	# By default, the daemon receives state updates following an
+	# event-driven model. You can modify this behaviour by switching to
+	# polling mode with the PollSecs clause. This clause tells conntrackd
+	# to dump the states in the kernel every N seconds. With regards to
+	# synchronization mode, the polling mode can only guarantee that
+	# long-lifetime states are recovered. The main advantage of this method
+	# is the reduction in the state replication at the cost of reducing the
+	# chances of recovering connections.
+	#
+	# PollSecs 15
+
+	#
+	# The daemon prioritizes the handling of state-change events coming
+	# from the core. With this clause, you can set the maximum number of
+	# state-change events (those coming from kernel-space) that the daemon
+	# will handle after which it will handle other events coming from the
+	# network or userspace. A low value improves interactivity (in terms of
+	# real-time behaviour) at the cost of extra CPU consumption.
+	# Default (if not set) is 100.
+	#
+	# EventIterationLimit 100
+
+	#
+	# Event filtering: This clause allows you to filter certain traffic,
+	# There are currently three filter-sets: Protocol, Address and
+	# State. The filter is attached to an action that can be: Accept or
+	# Ignore. Thus, you can define the event filtering policy of the
+	# filter-sets in positive or negative logic depending on your needs.
+	# You can select if conntrackd filters the event messages from 
+	# user-space or kernel-space. The kernel-space event filtering
+	# saves some CPU cycles by avoiding the copy of the event message
+	# from kernel-space to user-space. The kernel-space event filtering
+	# is prefered, however, you require a Linux kernel >= 2.6.29 to
+	# filter from kernel-space. If you want to select kernel-space 
+	# event filtering, use the keyword 'Kernelspace' instead of 
+	# 'Userspace'.
+	#
+	Filter From Userspace {
+		#
+		# Accept only certain protocols: You may want to replicate
+		# the state of flows depending on their layer 4 protocol.
+		#
+		Protocol Accept {
+			TCP
+			SCTP
+			DCCP
+			# UDP
+			# ICMP # This requires a Linux kernel >= 2.6.31
+		}
+
+		#
+		# Ignore traffic for a certain set of IP's: Usually all the
+		# IP assigned to the firewall since local traffic must be
+		# ignored, only forwarded connections are worth to replicate.
+		# Note that these values depends on the local IPs that are
+		# assigned to the firewall.
+		#
+		Address Ignore {
+			IPv4_address 127.0.0.1 # loopback
+            IPv4_address [IGNORE_IP1]
+            IPv4_address [IGNORE_IP2]
+            IPv4_address [IGNORE_IP3]
