# 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.
