+# Wildcard plugin to monitor ipfw nat aliasing links count
+#
+# Usage: Link ipfwnat_<nat number> to this file. E.g,
+#
+#	ln -s ipfwnat_ /etc/munin/node.d/ipfwnat_123
+#
+# ... will moninot nat number 123
+#
+# This plugin needs to be run as root. Sample plugins.conf:
+#
+# [ipfwnat_*]
+# user root
+#
+# Furthermore, nat configuration must contain "log" option. E.g.
+#
+# ipfw nat 123 config ip 198.76.28.4 log 
+#
+# This plugin is based on the if_ plugin.
+#
+# Magic markers (optional - used by munin-config and some installation
+# scripts):
+#
+#%# family=auto
+#%# capabilities=autoconf suggest
