-### BIG FAT DISCLAIMER
-## The "-i $WAN" is used to match packets that come in via the $WAN interface.
-## it WILL NOT MATCH packets sent from the $WAN ip address -- you won't be able
-## to see the effects from within the LAN.
+# The following chains are for traffic directed at the IP of the 
+# WAN interface

+iptables -F input_wan
