+# See arpwatch.8 for more information

+# Specify the interface for arpwatch to listen on here (default: lo).
+# If you need to listen on more than one interface, you should
+# run multiple arpwatch services; for example "arpwatch" and
+# "arpwatch.eth1". These additional services can be configured by
+# symlinking to the "arpwatch" service script, and by creating a new
+# conf.d file whose name matches the new service (symlink) name.
+#
+# Example:
+#
+# ARPWATCH_IFACE="eth0"
+#
+ARPWATCH_IFACE="lo"
+
+# Additional options to pass to arpwatch.
+# See arpwatch(8)
+ARPWATCH_OPTS="-N -p"
