#
# Shorewall version 4 - SMB Bi-directional Macro
#
# /usr/share/shorewall/macro.SMBBI
#
#	This macro (bidirectional) handles Microsoft SMB traffic.
#
#	Beware!  This macro opens a lot of ports, and could possibly be used
#	to compromise your firewall if not used with care.  You should only
#	allow SMB traffic between hosts you fully trust.
