# Shorewall version 4 - SMB Macro
#
# /usr/share/shorewall/macro.SMB
#
# This macro handles Microsoft SMB traffic. You need to invoke
# this macro in both directions. Beware! This rule 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.
