# 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.
