+# General note about log levels. Log levels are a method of describing 
+# to syslog (8) the importance of a message and a number of parameters
+# in this file have log levels as their value.
+#
+# Valid levels are:
+#
+#	7	debug
+#	6	info
+#	5	notice
+#	4	warning
+#	3	err
+#	2	crit
+#	1	alert
+#	0	emerg
+#
+# For most Shorewall logging, a level of 6 (info) is appropriate. Shorewall
+# log messages are generated by NetFilter and are logged using facility 
+# kernel and the level that you specifify. If you are unsure of the level
+# to choose, 6 (info) is a safe bet. You may specify levels by name or by
+# number.
+#
+# If you have build your kernel with ULOG target support, you may also 
+# specify a log level of ULOG (must be all caps). Rather than log its
+# messages to syslogd, Shorewall will direct netfilter to log the messages
+# via the ULOG target which will send them to a process called 'ulogd'.
+# ulogd is available from http://www.gnumonks.org/projects/ulogd and can be 
+# configured to log all Shorewall message to their own log file
