# Shorewall6 - isusable File
#
# /etc/shorewall6/isusable
#
#	This script is called when Shorewall6 is attempting to determine
#	if an interface named in /etc/shorewall6/providers is usable.
#
#	The script is invoked inside a function that accepts an interface
#	name as a single argument. The file below is designed to work with
#	both swping and lsm as described at
#	http://www.shorewall.net/MultiISP.html
#
# See http://shorewall.net/shorewall_extension_scripts.htm for additional
